Computer Fundamental What is Computer? Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations. A computer has four functions: a. accepts data b. processes data c. produces output d. stores results
Input Processing Output Storage
Input is the raw information entered into a computer from the input devices. It is the collection of letters, numbers, images etc. Process:
Process is the operation of data as per given instruction. It is totally internal process of the computer system. Output:
Output is the processed data given by computer after data processing. Output is also called as Result. We can save these results in the storage devices for the future use. Computer System All of the components of a computer system can be summarized with the simple equations. COMPUTER SYSTEM = HARDWARE + SOFTWARE+ USER •
Hardware = Internal Devices + Peripheral Devices All physical parts of the computer (or everything that we can touch) are known as Hardware.
Software = Programs Software gives "intelligence" to the computer.
USER = Person, who operates computer.

On the basis of Size a) Super Computer
The fastest type of computer. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration. The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently.
b) Mainframe Computer
A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. In the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe.
c) Mini Computer
A midsized computer. In size and power, minicomputers lie between workstations and mainframes. In the past decade, the distinction between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstations. But in general, a minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.

d) Micro Computer
i. Desktop Computer: a personal or micro-mini computer sufficient to fit on a desk.
ii. Laptop Computer: a portable computer complete with an integrated screen and keyboard. It is generally smaller in size than a desktop computer and larger than a notebook computer.
iii. Palmtop Computer/Digital Diary /Notebook /PDAs: a hand-sized computer. Palmtops have no keyboard but the screen serves both as an input and output device.

A terminal or desktop computer in a network. In this context, workstation is just a generic term for a user's machine (client machine) in contrast to a "server" or "mainframe."
On the basis of Brand a) IBM/IBM Compatible Computers
Booting The process of loading the system files of the operating system from the disk into the computer memory to complete the circuitry requirement of the computer system is called booting. The system files of MS. DOS are: Types of Booting: There are two types of booting: • Cold Booting: If the computer is in off state and we boot the computer by pressing the power switch ‘ON’ from the CPU box then it is called as cold booting.
- 15 -
Warm Booting: If the computer is already ‘ON’ and we restart it by pressing the ‘RESET’ button from the CPU box or CTRL, ALT and DEL key simultaneously from the keyboard then it is called warm booting.
How to start the Computer in Ms. Windows mode? There is nothing special you need to start this system. Just, 1. Switch ON the Power Supply. 2. Switch ON the CPU and, 3. Switch ON the Screen (Monitor). How to Shutdown (Turn Off) the Computer? Before shutting down the Computer, close all opened windows at first. Then, 1. Click on Start button. 2. Click on Shutdown (Turn Off Computer). Then, Computer asks you: What do you want the Computer to do? • Standby • Shutdown (Turn Off) • Restart • Restart in MS-DOS mode.

Windows XP Windows XP is an operating system which runs as an interface between the computer and you to help you use the PC and allow you to run complex applications. To open up Windows XP, you need to first login with your userid and password.
1. The Desktop 1.1 Overview The Desktop is where you start when you first log in and it refers to the computer screen and includes the taskbar across the bottom and icons which are shortcuts to run applications. The Desktop will always be there during the session, behind whatever else you do. The Desktop is where you start to access any files, folders or applications and so, when viewing folder structures, is placed at the top of the hierarchy of places to which you might go. THE DESKTOP
Click here for menu
taskbar icons for applications
1.2 The Taskbar The Taskbar appears along the bottom of your screen and includes the Start button and clock.
When an application is running a button appears on the taskbar. This has the appearance of being pressed in if the application is the active one (i.e. the one currently being used). To switch to another open application, click on its taskbar button and the window will open as the active one.
Taskbar operations To display tooltips: Hover with the mouse over the button on the taskbar - hovering over an application button gives the name of the file that is open in that application. To display the date Hover with the mouse over the time and the date will display in a tooltip. To minimise all open applications Right click on an empty part of the taskbar, then choose Show the Desktop. All the open windows will be minimised to the buttons on the taskbar, so displaying the desktop. The menu option will then change to Show Open Windows, ready for restoring them all. Clicking on an individual button will display the window for that one only. To tile or cascade windows Right click on an empty part of the taskbar, and then choose Tile Windows Horizontally, Tile Windows Vertically or Cascade Windows To view the task list This is a way of viewing a list of the applications running on the PC and their status. Right click on an empty part of the taskbar, and then choose Task Manager. Under the Applications tab you can see the list. From here you could select an application that was not responding and use the End Task button to close it down.
Taskbar customisation Right click with the mouse on an empty part of the taskbar and choose Properties. Unlocking the taskbar If you take the tick off ‘Lock the taskbar’, you will then be able to drag it elsewhere on the desktop, adjust divisions between taskbar areas and change its depth. Auto-hide the taskbar If this option is ticked, the taskbar will only appear when your mouse pointer approaches the bottom of the screen. Ensure the taskbar is visible If you have the option ‘Keep the taskbar on top of other windows’ ticked, then the taskbar will still be visible, even when an application window is maximised. Group similar taskbar buttons Ticking this option means, that when more than one instance of an application is running, the taskbar buttons will either be next to each other, if there is room, or will be consolidated onto one button. Clicking on the one button will list the open files. Displaying the Quick Launch toolbar By ticking ‘Show quick launch’, a useful set of buttons appear on the taskbar next to the Start button. Initially there are shortcuts for your web browser, email application and a Show the desktop button, which will minimise all the open windows. Further shortcuts can be added here.
1.3 The Start Menu The Start Menu is where you can begin to do anything – it provides means to run any installed application and find any files that are on the computer, as well as customise how it is set up. Start Menu operations To display the Start Menu A single click on the Start button displays the Start menu. To close the Start Menu Click on any empty space on the desktop. Starting applications from the Start Menu There is a list of useful shortcuts to applications down the left side of the Start menu. There is a dividing line: those above the line (the pinned items) are constant, but you can add extra ones here yourself; those below the line (the most frequently used programs) will change to reflect the applications you use most often. A single click on a menu item will run it. If a menu item has an arrow beside it, then you can hover over it to display further menus. Hovering over All Programs with your mouse pointer will display a list of all available applications.
Start Menu customisation Right click with the mouse over the Start button and choose Properties. Here you could change the style of the Start menu to be similar to earlier versions of Windows. Clicking on the Customize button brings up your customisation options
From here you can choose the number of frequently used programs that will be listed, and you can clear this list.
From the Advanced tab, there are many other options.
To display a program at the top of the Start Menu Right-click the program you want to display as a pinned item on the Start menu. This program could be a link on the Start menu, in Windows Explorer, in My Computer, or on the desktop. Then click Pin to Start menu. You can remove a program from the pinned items list by right-clicking the program and then clicking Remove from This List. You can change the order on the pinned items list by dragging a program to a new position.
1.4 Desktop icons The desktop icons are shortcuts to applications or files. A double click will run the application A single click selects an icon (– if you then press Enter the application will run). A right click on an icon brings up a shortcut menu. From here you can choose to rename it, open it, delete it or look at its properties. Re-aranging icons You can move an icon by clicking on it with the mouse and dragging it. You can re-arrange icons by right-clicking on an empty part of the desktop, and choosing ‘Arrange Icons by’, then choose an option. Autoarrange will always put the icons back if they get dragged out of place.
Creating a desktop shortcut Right click on the desktop, choose New, then Shortcut. Click on the Browse button to choose the application/file for which you want the shortcut. After Next you can choose the name for it. Finish will create it. Alternatively, you can drag an application on to the desktop from the Start menu for instance, or you can right click on an application link, choose Send to, then Desktop (create shortcut).
1.5 Desktop settings Customisation of the desktop is done by right-clicking on an empty part of the desktop and choosing Properties. Changing the display style Under the Themes tab, from the drop down list by the Themes box, choosing Windows XP gives you the normal XP look. (Windows Classic is a style very similar to previous versions of Windows, such as NT.) Then click OK. Changing the resolution If you think that everything on your screen is too small or too large then you may want to try changing the screen resolution. Choose the Settings tab, then drag the Screen Resolution slider to what you want – perhaps to 800 by 600 pixels. Then click OK.
2. To Close Down the PC To log off and leave the computer running From the Start menu, click on Log Off. You can choose to either close your programs and log off or leave your programs running and log on as a different user. To close down the PC From the Start menu, click on Shut Down.

To minimize a window Click on the Minimize button. The application will shrink down to a button on the taskbar. Clicking on the taskbar button will bring it back. To resize a window Click on the border and drag to the size required. Dragging the corner enables both sides to be resized at once. To close a window Click on the X at the top right corner. The application will be closed down. The Control Box Clicking this brings up a menu for some of the above operations. Double clicking closes the window. Scrolling If all the content of the window is not visible there will be a scrollbar(s). Click on the arrows at each end of a bar to scroll. Moving between open windows Alt+Tab or click on a taskbar button.
See Appendix A for a fuller list of Windows operations for mouse and keyboard
5. Drives, Folders and Files See ‘Where to save your work’ in Appendix B for information about the different drives. Files on a computer drive can be saved into folders, which are arranged in a hierarchical or tree structure. You can create your own folders into which you can save your files, so as to make them easy to find again. You should keep your own files separate from any existing files on your computer, as these may be system files that are needed to run the computer. My Computer This is a collection of the drives accessible to you from your computer, such as your floppy drive or CD ROM drive. It appears in the Start Menu and sits directly under ‘The Desktop’ in the hierarchical structure. You can also access your personal and shared network drives (h: and s:) from My Computer, but not other computers on the network. Your local area on the network will be labelled with your login name e.g. Itnjh on ‘User1\Staff\User’ (H)). The H is not always visible being at the end of the label.
W INDOWS XP
A USER GUIDE
My Documents When you are logged in to the network on a University PC, My Documents is set up to point directly to your H: drive, your home area on the network. (It would otherwise point to an area in your profile on the C: drive.) ‘My Documents’ appears in the Start Menu and sits directly under ‘The Desktop’ in the hierarchical structure. You will also see links to My Documents throughout Windows as you work, so the direct link to H can be useful when you want save or find your own files. Saving your work Within an application, the menu item File, Save As takes you to a dialogue box. From here you will need to choose where to save your work as a file and give the file a name. This is a typical Save As screen: Choose drive here where file is to be saved Go up a level
Contents of drive/ folder shown in Save in box. Double click a folder to display the contents
Direct link to H drive
Type new file name here
Save in box. Click on the black arrow to the right of the box and choose the drive you require (usually H:). Alternatively to get to H, click on the My Documents button. The contents of whatever drive or folder is showing in the Save in box are displayed in the space below. Double clicking on a folder opens it (putting its name in the Save in box) and displays its contents below. You can repeat this and so go down the tree structure until you are displaying the folder where you want to save. If you need to go back up the structure, use the icon with the up arrow to the right of the Save in box. Give the new file a name in the File Name box. Click on the Save button.
© THE ROBERT GORDON UNIVERSITY
Finding your files Within an application, the menu item File, Open takes you to a dialogue box. From here you will need to choose where your work was saved. The Open screen is very similar to the Save as screen above and you navigate through the file structure in the same way, until you have found the folder where your file is. You then select the file and click on the Open button. If you cannot find your file then you can use the Windows Search facility. Search This Search facility is accessed by clicking on Search on the Start Menu or by clicking on the Search toolbar button within My Computer or My Documents. A Search Companion pane shows down the left of the window and you can specify various known criteria to assist in the search. For instance you may know when it was last modified or part of the file name. You can even specify a word contained in the document. You will need to make sure it is searching within the appropriate drive – you may need to change the drive from C (the default) to H. This is done after choosing ‘More advanced options’. An Example: You might choose Documents. You could leave the Name box: blank to search for all files and folders in a drive or folder or you could type as much of the name as you know, using the wildcard * for unknown parts e.g. *.doc would find all Word files, b*.doc would find all Word files beginning with b, and *.xls would find all Excel files. Advanced options allow you to select the drive to search by clicking on the black arrow to the right of the Look in box and choosing a drive or type the path to a particular folder in the Look in box in the form h:\courses. If you can narrow the search by filling in when it was last modified it will speed up the search.

You could also include a word from the document to help the search.
6. File Management You may be used to using Windows Explorer from previous versions of Windows, and you can continue to use it. However the screen is very similar with one exception to that of the folder windows displayed from My Documents or My Computer, which I suggest you may now want to use for your file management tasks.
6.1 Windows Explorer You can find Windows Explorer from the Start menu, All Programs, Accessories. If you like to use this and find it a bit inaccessible there, you could pin it to the Start Menu (see Section 1.3). The left pane displays a tree structure of drives and folders: ‘The Desktop’ at the top level and ‘My Computer’ at the next level down. The drives available to you are shown next with the folders on those drives arranged in the structure below each. A folder is selected with a single click and it appears blue. The right pane displays the contents of the selected folder. The path of the currently selected folder appears in the Address box at the top left of the screen. The only difference between Windows Explorer and the Folders windows described next are that Windows Explorer opens with the Folder list option already chosen. If you were to click on the Folders button on the taskbar it would then be the same.

6.2 Folder windows Overview Elsewhere, when displaying a folder in a window, such as from My Documents or My Computer, there is a Task Pane at the left of the window, which lists links to common file and folder management tasks. You can select a file or folder, and then click a task. These tasks change according to what you have selected, but will probably include renaming, copying, moving, and deleting.
Expanding the Details area will show information about the item selected, such as when it was last modified.
Several folders provide links to specialized tasks.
If you prefer to replace the task pane at the left hand side with a folder structure (like in Windows Explorer), so as to make it easier to find your way around, click the Folders button on the toolbar (or go to the VIEW menu, Explorer Bar and choose Folders). To put the pane back, click the Folders button again (it is a toggle) or go back into the menus and take the tick off. Panes can be resized by dragging the central border. You can also choose how you want the files and folders at the right hand side to be displayed. This can be done from the View menu or by clicking on the View button on the toolbar. This will change the view for the current folder only.

Folder Options Options about the Folder window for customising it are found from the TOOLS menu, then Folder Options. Some examples: File extensions If you want to see file extensions (i.e. the .doc at the end of the name for a Word file etc.), go to the Folder Options and choose the View tab and it is in the Advanced settings list (-no tick for ‘Hide extensions for known file types’). Icon types If you want to see a list of the different icons with information about them, go to Folder Options and the File types tab. Changing the view for all folders If you want to change the view for all folders, for instance to show Details, then you should change the current folder to Details, then go to the TOOLS menu, Folder Options, the View tab, then click on the Apply to all Folders button.
Navigating Whether the Folders list is showing or not, it is the same structure of drives and folders that you may want to navigate around. The path of the currently selected folder appears in the Address box at the top left of the screen. Folder structure When the folder list is showing, you can view the hierarchical structure of folders: ‘The Desktop’ at the top level, ‘My Computer’ at the next level down. The drives available to you are shown below My Computer with the folders on those drives arranged in a tree structure below each. You will be able to see ‘My documents’ at the same level as My Computer for convenience, but it is the same as the root (top of) of the H drive. This is where you will most usually be keeping your work, but it is useful to build your own structure of folders below this so you can organise your files. Moving around the structure When you see a folder name, either in the right pane or on the Folders list, double clicking on it will open it. The new path will appear in the Address box and the contents of the folder are displayed in the right pane. You can thus step down through a hierarchy of folders. Toolbar buttons can be used to move back up through the structure, or you can double click on a drive or folder name on the Folders list if visible.

Using the toolbar buttons There are some useful buttons for navigating around your folders. There are Back and Forward buttons to revisit places you have been
and an Up button to move up a level in the folder structure. You can also add a file or folder to your Favorites (a menu item) and then you can quickly bring it up again by choosing it from your list of Favorites. There is a Search button on the toolbar which opens up a Search pane at the left of the window, from which you can search for files or folders. This is similar to doing a Search from the Start menu (see Section 5). Using the Folders list Double clicking on a drive or folder in the Folders list, selects the drive or folder and displays the contents at the right hand side. It also expands the tree to show any folders at the next level down. A single click selects the drive or folder and displays the contents at the right hand side, but does not expand the structure. You will see a + or – sign by a drive or folder name. A single click on the sign will either expand or collapse the structure, but will not change the file selection. Thus the display at the right hand side will not change, as it always shows the contents of the selected drive or folder. Arranging the view of files and folders When you are looking at the contents of a folder, you can arrange the contents to suit you in various ways. As well as choosing how the files and folders display (as icons, showing details etc.), you can also arrange them by name, size, type and date modified. This can be done from the View menu, Arrange icons by, and then choosing which you want. The same arranging can be done also in Details view, by clicking on the appropriate heading in the right hand pane. For instance, clicking on the heading Date Modified, will sort the contents in date order. Clicking on a heading a second time will reverse the sort, from earliest first to most recent first, or from AZ to Z-A. In Details view further details can also be displayed. From the View menu, go to Choose Details, then select from the list. You could display the number of pages or the date each was created. The View menu allows you to toggle the toolbars and status bar on and off

Where to save computer files. The computer drive options are: Computer’s own hard disk This is a disk inside each computer that is known as the C: drive. This is where you can save work on home computers, but it is not advisable at The Robert Gordon University. If there is a serious problem with your PC then this hard disk could be wiped in the recovery process and you would lose your work. Floppy disk This is a small removable disk that is useful for backups or for transferring files between work and home. The computer knows the floppy disk drive as the A: drive. You should not work directly from these disks as not only will it be very slow, but they are also not reliable enough. Network Drives Every computer user at the University is given an account to use the network. You are allocated a personal area of storage space on the network known as the H: drive (H for home). This is where your work should be stored. This storage is reliable, secure and is backed up every night. If you are sharing files with colleagues then you may need to use the shared drive on the network known as the S: drive.

Starting Microsoft Word To load Microsoft Word: 1. Click on the Start menu in the bottom left corner of the screen 2. Choose All Programs then Microsoft Office (from the sub-menu which appears) 3. Finally click on Microsoft Office Word 2007 Tip: You'll probably be using Word quite frequently in the future, so it's worth putting it as an icon on the Desktop. To do this, repeat the above steps, but at the last step, right click (ie press the right mouse button) and choose Send To followed by Desktop (create shortcut). To load Word in future, simply double click on the Desktop icon.
The window shown below will open, ready for you to begin typing. The image part with relationship ID rId141 was not found in the file.
The image part with relationship ID rId142 was not found in the file.
Office Button In the top left-hand corner is the [Office] button which can be used to open and print your document. To the right of this is the Quick Access Toolbar which contains icons to a few commands, eg save and undo, and to which you can add further buttons. Below this is the Ribbon, with tabs along the top and command buttons on each tab. These can be used to give instructions to Word. Scroll bars are provided on the right (and bottom) to let you move up and down (or sideways across) your work. At the very bottom of the window, there is information about where you are in your document on the Status Bar - here you are on Page 1. The information that is shown on the Status Bar is a word count and the language you’re working in. On the right-hand side of the Status Bar are icons to change the view of the page, and to zoom in or out, ie make the text on the screen bigger or smaller.
Writing Your Document You next need to decide how you want the rest of your text to appear. It's easiest to set this up before you start typing - the settings will then be carried forward from one paragraph to the next.
Changing Fonts The image part with relationship ID rId143 was not found in the file.
Font The starting font for a new document in Word 2007 is usually set to Calibri (Body). You might want to use a different style of lettering (font or typeface) to personalise your work. Several fonts are available in Word. If you want to change the current font: 1. Click on the list arrow attached to the [Font] button on the Home tab 2. Click on the font you require, eg Times New Roman – you can either scroll down the list to find the font you want, or type in the name of the font to pick it up more quickly Tip: It's best to stick to true-type fonts (those labelled TT) to maintain your document's portability. Some fonts (eg Symbol and Wingdings) produce non-Roman letters or iconic symbols. Courier New gives a typewriter font. Sans-serif fonts, such as Ariel, give clear headings. 12
Changing Font Size The image part with relationship ID rId144 was not found in the file.
Font Size Generally a point size of 10, 11 or 12 is used for the body of the text while point sizes of 13 to 16 are used for headings. The current size (11) is shown in the font size box. To alter this: 1. Click on the list arrow attached to the [Font Size] button on the Home tab 2. Click on the size you require - for example, 12 Tip: You can also type the number directly into the font size box (press to set it). This allows you to select a font size not in the list, for example 13 or a bigger number if you want very large characters.
Entering Your Text 1. Type in a few words, pressing the once after each word to separate them (the spacebar is the long key along the bottom of the keyboard) If you are not very fast at typing just type some imaginary words, pressing keys at random, but remember to include spaces between your words. Remember that if you want to improve your typing, there is an AccuType training tutorial on the IT Services PCs (you can also buy a copy for a personal computer). 2. Continue typing across the screen - the words will automatically spill onto a new line when you reach the right-hand side (this is known as wraparound) 3. Continue typing until you have at least three lines of words then press to mark the end of the paragraph (this is the upside-down L-shaped key on the right of the main keyboard – it is also located on the far right of the keyboard, in the numeric keypad, with the word Enter written on it) IMPORTANT: When using a word processor, do NOT press the key at the end of each line. If you need your work double spaced (each line followed by a blank line) then you simply change the paragraph's line spacing - this is covered later on. Press only when you want to start a new paragraph. A jagged red (or occasionally green) line may appear beneath your text. Don't worry about this - Word is telling you that what you typed is not recognised (the words are not in the dictionary) or that the grammar may be incorrect. You learn more about this later. Tip: Never press the or key more than twice in succession. In particular, do not use spaces to centre a heading or line up words in columns, or to add extra blank lines to force a heading onto a new page. There are special key presses that do this for you (tabs and hard page breaks) that are covered in our Microsoft Word Intermediate Guide. 4. Practice typing a couple of extra paragraphs, pressing at the end of each
Correcting Mistakes Don't worry if you go wrong, as it is very easy to correct your work. The key (immediately above in the main section of the keyboard) can be used to delete the last character(s) typed. 1. Press a few times and note what happens You should have noticed a flashing vertical bar on the screen at the end of your work. This marks the insertion point. Anything that you type will always appear at the insertion point. You can move the insertion point around your work by using the arrow keys to the right of the main keyboard. You can also change its position by moving the mouse pointer on the screen and clicking where you want the insertion point to be. 2. Press the keys to move the insertion point around - note that you can hold down a key to move more rapidly 3. Move the mouse to position the pointer in the middle of a paragraph and click on the mouse button the insertion point should have moved to where you clicked 13
4. Type in some more words - watch how the text which follows moves sideways to make room for the new words As the text moves, the following lines of the paragraph are redrawn automatically. Within a paragraph, the key works as before but you can also remove characters forwards: 5. Press the key (immediately to the right of ) a few times and note what happens Here you are only practicing on text you do not need to keep, but you may accidentally delete words that you needed. Do not panic! If you ever make a mistake when using Word then you can undo your error by using the [Undo] button. The image part with relationship ID rId146 was not found in the file.
Undo This can be found on the Quick Access Bar in the top left-hand corner. The undo button can be used more than once, to undo a series of actions, one at a time. 6. Click on the [Undo] button several times to see its effect Note: There's also a [Redo] button (to the right of [Undo]) if you accidentally undo too much! Tip: Word lets you use control key combinations to issue commands from the keyboard. The combination (hold down and press ) can be used to undo something. can be used for redo.

With Microsoft Word, it's easy to change the appearance of your work. Changes to the way a paragraph is laid out can be made by first moving the insertion point into that paragraph (anywhere will do). You can then decide how you want your paragraph to look. 1. Move the insertion point into the paragraph you want to change When typing a document you normally want text to align on the left-hand side of the page. Some people prefer text to be fully justified - this is where text aligns both left and right. You can also align text to the right (eg for an address) or to the centre (eg for a title or heading). You can use the buttons shown above (they are on the Home tab in the Paragraph group) to control how text is aligned on the page. 2. Try out all four justification buttons (or use , , and ) - note that only the current paragraph is affected; each paragraph has its own justification setting Tip: If you like justified text, consider turning on hyphenation. This automatically splits a long word at the end of a line in two, improving the layout considerably. To turn this on, click the Page Layout tab, then the [Hyphenation] button in the Page Setup group and choose Automatic.
Altering Line Spacing The image part with relationship ID rId151 was not found in the file.
Line Spacing Sometimes you might be asked to double space your work (or use some other spacing). You might even choose to have a quotation (for example) one-and-a-half spaced, with the rest of your text double spaced. You should still be in the paragraph where you tested the different justification settings. 1. Click on the list arrow attached to the [Line Spacing] button in the Paragraph group 2. Select 2.0 for double spacing Tip: You can also use (hold down and press ) for double, for single and for one-and-a-half spacing. adds a blank line before a paragraph. 14

As well as changing the font and font size, you can make some other fairly simple formatting changes that change the look of your text. Here try out the bold, italic and underline buttons which are in the Font group on the Home tab. 1. Move to the bottom of your current document. A quick way to do this is to use the control key combination (the key is located in the block of six keys to the right of the main keyboard letters). Press until you’re on a new line 2. Click on the [Bold] button and type in some new words. You will find that these words appear in a blacker colour. To turn off bold, click on the [Bold] button again 3. Try out the [Italic] and [Underline] buttons as in the above step Note that you can have your text with more than one of these options set on - bold italic or underlined italic, for example. For emphasis, it is usually best to stick to bold. Italic is often used in the title of a paper or journal in bibliographies or references, and underline can be used for a heading or subheading. Tip: The control key combinations to get bold, italic or underline are respectively, for bold, for italic and for underline.
Saving Your Work You should save your work regularly - ideally every 10 minutes so that you don't lose what you have typed should the computer stop working. Word does have an autosave facility which should guard against loss of work; however this is not a proper save and should not be relied on. 1. Click on the [Office] button in the top left-hand corner and then choose Save (or use the [Save] button on the Quick Access Toolbar ) The image part with relationship ID rId155 was not found in the file.
For a new document, a Save As dialog box similar to that below will appear: The image part with relationship ID rId156 was not found in the file.
2. Type a name for your work (eg my first document) - there's no need to clear the File name: box first; whatever you type will replace what's there already 15
Note: you should mainly use letters and numbers for your file names (spaces, hyphens and underscores are also permitted); DO NOT use any other punctuation marks as they can cause problems. Your work will be saved to My Documents, which has been set up to be on drive N: on the computers on campus. This is an area on the network where you can save your own work, known as your home directory. No one else has access to your home directory; you connect to it whenever you logon to an IT Services computer. Backup copies of the files in your home directory are made hourly, so you should never lose any of your work. Though the [Save] button shows a picture of a floppy disk, it is NOT a good idea to work directly from floppy. They can easily be damaged (or lost) and work can be corrupted if they become full. We recommend you only use floppy disks to move your files from one computer to another (this also applies to more modern media such as memory sticks and CDs). Note: By using Save As rather than Save, you can save your work as a Word 97-2003 document so that it is compatible with earlier versions of Word. This will make it easier for anyone who has an older version of Word to open the document. However, any features that are only available in Word 2007 may not be saved (a warning will come up to say which features these are). 3. Press or click on [Save] Once you have given your document a name, this will appear (instead of the original name, eg Document1) at the top of the Word window. Note that the extension .docx (or .doc for Word 2003 documents) is added automatically. Tip: It is a good idea to save your work regularly (eg every 10 minutes or so). The easiest way to do this is to press periodically.
Working with Selected Text Selecting text is very important as it identifies which section of text you want Word to modify. It can be used to change how some text looks, to move or copy text within a document, between documents or between different applications (eg Word and PowerPoint), and to delete or replace text. A simple way to select part of your text is by dragging through it as follows: 1. Move the mouse so that the pointer on the screen is at the start of the text that you want to change 2. Hold down the mouse button, and keep it held down 3. Drag the mouse sideways to move the pointer to the end of the text that you would like to change – the selected text now has a blue background 4. When you are happy with your selection, release the mouse button You may have noticed that a set of option buttons have appeared just to the right of your selected text like in the example below: The image part with relationship ID rId157 was not found in the file.
These different buttons immediately allow you to change the look of the selected text, eg make it bold, alter the font or size, turn it into a list etc. If you accidentally go wrong and select the wrong text, click the mouse once (this will release the selection) and try again. Tip: Minor adjustments to a selected area can be made by holding down the key and pressing the or key. This method can also be used instead of dragging through the text. Rows of text can be selected using the or keys.
Tip: If ever you want to replace some words with something different, simply select the words to be replaced and then type the new ones (the selected text automatically disappears). You can also delete a section of text by first selecting it and then pressing the or key.
Selecting the Text Selecting can be done in several different ways, depending on how much text is involved. Any selected text can be de-selected by clicking on the mouse button once. Try out the following: •
A single word - point to it using the mouse then double click on the mouse button - your selected word should be highlighted. Click once on the mouse to de-select it
A single line - position the mouse pointer in the left-hand margin (where its shape changes to an arrow pointing inwards) and click once
A whole paragraph - either double click in the left margin or click three times within the text
The whole document - either click three times in the left margin or press
A sentence - hold down and click anywhere within the sentence
A short piece of text - drag through the text to be selected
A long piece of text - click at the start of the text to be selected then move down, using the scroll bars, and hold down as you click at the end of the selection
To modify an existing selection - hold down and use the arrow keys
Cut, Copy and Paste The image part with relationship ID rId161 was not found in the file.
Format Painter -
The above buttons are visible on the far left of the Home tab in the Clipboard group. Moving text around a document is done by: i.
Cutting or copying it from its present position
Pasting it back to its new one
You can copy information within the same document, from one document to another, or from one program to another (for example, text on a web page can be copied into your Word document). 1. Move to the top of your document (pressing takes you straight there) and select the first paragraph of text (double click at the left or three times within the paragraph) 2. Click on the [Cut] button and the paragraph will disappear - do not be alarmed, it has not been lost, but has been copied onto the clipboard 3. Move the insertion point down to the end of your text (pressing moves you straight there) – add a new line if necessary by pressing 4. Click on the [Paste] button - your original paragraph will be pasted into its new position Tip: You can also use to issue a cut command - gives copy; paste. The image part with relationship ID rId162 was not found in the file.
You’ll find that a paste options icon appears next to the pasted text – clicking on this will give further options to how you want the pasted text to look (leave it as Keep Source Formatting - it won’t disappear until you do something else like adding some more text). 17
Note: You can also use right click on selected text and choose Cut or Copy from the shortcut menu, then move to the new position and finally right click there and choose Paste from the shortcut menu. Note also the [Format Painter] button. This is used to copy the format (font and/or paragraph settings) from one piece of text to another: 5. Select the text (or paragraph) whose format you wish to copy - try the text you made bold earlier 6. Click on the [Format Painter] button (the pointer becomes a paintbrush) 7. Drag through another piece of text - release the mouse button and it too becomes bold This can be especially useful in the case where you notice that a paragraph looks different from the rest of the paragraphs on that page, maybe because it is in a different font. You can use the [Format Painter] button to quickly correct this problem.
Making Multiple Copies and the Clipboard When making multiple copies of text, you normally Copy rather than Cut it to the clipboard: 1. Select some text (a few words will do) and click on the [Copy] button (or press or right click and choose Copy) 2. Your original text will remain where it is, but a copy of it has been placed on the clipboard 3. Move the insertion point to where you want to paste the text 4. Click on the [Paste] button (or press or right click and choose Paste) 5. Repeat the above step and a second copy of the text will appear The clipboard, which is normally hidden, will only store the last item that you cut or copied but, after displaying it, up to 24 items can be stored on it. To display the clipboard: The image part with relationship ID rId163 was not found in the file.
6. Click on the Clipboard group arrow just below the [Format Painter] button – this will open the Office Clipboard in a Task Pane on the left 7. Select another part of your text and [Copy] it - watch it appear on the clipboard 8. Move the insertion point then click on the new clipboard entry to paste it into your text 9. Repeat the above step but click on the original clipboard entry You won't need to paste any of the text again, so it's a good idea to empty the clipboard: 10. Click on the [Clear All] button in the Clipboard pane 11. Close the Task Pane by clicking on its [Close] button (the little x in the top right corner)
Drag and Drop If you wish to move text a short way then you can use the drag and drop technique: 1. Select some text - a few words is sufficient 2. Move the mouse pointer into the highlighted area then hold down the mouse button (the pointer becomes an arrow with a box attached and in the left-hand corner of the Status Bar at the bottom of your Word window it says Move to where?) 3. Keeping the mouse button held down, drag the text to a new place in your document (as you move the cursor a faint dotted line appears - this is where the selected text will be dropped) 4. Release the button - the text will be moved to its new position 5. Practice moving selected text to other positions Tip: The key combination with the key moves a selected paragraph up or down the page one paragraph at a time.
Further Formatting Most of your text will be with the same layout of paragraphs. However, sometimes you will need to change the layout for other special sections (eg for a list).
Bulleted and Numbered Lists The image part with relationship ID rId164 was not found in the file.
Numbering The image part with relationship ID rId165 was not found in the file.
It is often useful to create lists using either bullets or numbers. The [Bullets] button gives you a bulleted list: 1. Move to the end of the text (press ) and make sure you are on a blank line 2. Click on the [Bullets] button (on the Home tab in the Paragraph group) – a bullet point should appear 3. Type a couple of words against each bullet point, pressing once after each one 4. Press twice at the end to turn the bullets off Numbers are applied in a similar fashion using the [Numbering] button: 5. Click on the [Numbering] button - a number 1. appears 6. Type in two short paragraphs (one a couple of lines long), pressing once after each one Note that each paragraph is numbered and that the first line of text is indented slightly to allow for the number. The second line of text is also indented, to line up with the words of the first line. 7. Move to the end of the paragraph numbered 1 and press - a new number will be inserted in the correct sequence with later lines re-numbered 8. Press (the button to the left of the letter Q) and the numbering changes to a and is indented further – type a few characters 9. Press (the letter b appears) then (the letter changes to the number 2) 10. Press and the extra line will disappear 11. Move to the last line in the numbered list (which should be empty) and press - this should turn numbering off Tip: Sometimes you might want more than one paragraph under a bulleted or numbered point. To achieve this, hold down as you press to end a paragraph (it’s best to have the text left-aligned – justified text doesn’t look good).
Correcting Spelling and Grammar The image part with relationship ID rId166 was not found in the file.
Spelling and Grammar Word checks the spelling and grammar as you type. A red squiggly line under a word denotes that Word thinks it has been spelt incorrectly; if the line is green then the grammar may be incorrect. You can check the whole or part of the text for mistakes using the [Spelling and Grammar] button. 1. Press to move to the end of your text then for a new line 2. Type the following misspelt text: howe mamy speling andother erors is there on thsi sentance? There was 10.
Note that as you type the words, Word automatically corrects certain mistakes: •
it capitalises the first word in a sentence (Howe) 19
it corrects certain misspellings (eg erors to errors, thsi to this and sentance to sentence)
3. Select the line of misspelt text (eg click 3 times on it) - Word can spell-check just a selected area 4. Move to the Review tab and click on the [Spelling and Grammar] button on the left of the Ribbon The image part with relationship ID rId167 was not found in the file.
5. Choose the correct spelling of many in the Suggestions: box – press for [Change] 6. Continue in the same manner with the other corrections 7. Always check the correction is what you want - with andother choose and other If Word gives you no suggestions (or doesn't show the correct one in the list) you can edit the text in the Not in Dictionary: box. Also if a spelling is correct but not in the dictionary, you can either choose to [Ignore] a suggested correction or [Add] the word to your own dictionary. Choose [Ignore All] if you don't want to be asked about the same spelling again (similarly [Change All] will change all occurrences of a misspelt word). You can also [Close] or [Cancel] the check at any time. Once the spelling check is complete, the grammar checker is run. This isn't foolproof, but it does pick up some common grammatical mistakes. At the end of the grammar check: 8. Click on [No] - you don't want the rest of the document checked 9. Press to deselect the highlighted text then to start a new paragraph Tip: If you just have one word that is misspelt (or a phrase with bad grammar), move the mouse pointer over the error and click on the right mouse button. A list of likely correct spellings appears. If the spelling you want isn't in the list, choose Spelling... (or Grammar...) to start the checker. Note that you will still need to proof read your work to pick up, for example, correctly spelt words used in the wrong context. Here, Howe was not corrected because it was recognised as a surname - it would have been picked up had it not been capitalised (by Word itself!). Similarly, on needs manual correction to in. Also, though was was corrected to were in the second sentence, the grammar checker failed to notice that is in the first sentence had a plural subject and should be are.
Closing a Document Although you can have more than one document open in Word, if you have finished working on a file, it is a good idea to close it. Before closing it, remember to save it: 1. The quickest way is to press As you’ve already saved your document previously, this time it won’t come up with any Save As window, but will automatically save the latest version of your document overwriting the previous version. If you did want to save your document under a different name, into a different place or in a different format then you should choose one of the options under Save As. 21
To close the current document without exiting from Word: 2. Click on the [Office] button in the top left-hand corner and then choose [Close] Tip: You can close a document from the keyboard using the key combination .
Opening an Existing Document You may want to do some further work on an existing document. In this next exercise you will be opening the file you have just closed. The notes which follow assume that your work was saved to My Documents on drive N: (your home directory). If your file is on a USB memory stick or a floppy disk, then you should first copy it to My Documents (see Microsoft Windows XP Beginners' Guide for details of copying/moving files between different media). IMPORTANT: If you open a file direct from a USB memory stick or floppy disk then you must not remove the pen or disk until you have properly closed the file (or disconnected the memory stick). If you don’t do this, it can result in your files being corrupted and you may lose your work. Never swap pens or disks or you may corrupt them both. 1. Click on the [Office] button and choose Open Note the list of Recent Documents on the right-hand side – from here you can open up your latest documents and can pin documents permanently to the list. The [Open] button on the Quick Access Toolbar (or the key combination ) can be used to open a file but you then don’t see the list of Recent Documents. The image part with relationship ID rId169 was not found in the file.
You will see a dialog box similar to the following, showing any folders and Word files in My Documents: 2. Click on the name of your file you want to work on, eg my first document.docx The image part with relationship ID rId170 was not found in the file.
3. Press or click on [Open] Use the key (above the arrow keys) to move down your document or to go to the end of your document. Note: You can have more than one document open at a time in Microsoft Word. This allows you to copy text from one document to another. You can move between documents by clicking on the View tab and then the [Switch Windows] button (or the buttons on the Taskbar, normally located at the bottom of your screen).
Starting a New Document To start a new empty document at any time from within Word: 1. Click on the [Office] button and choose New 2. A New Document window will open – the Blank document icon will already be selected so just click on [Create]
If you use the [New] button on the Quick Access Toolbar (or the key combination ) then the new document appears immediately Tip: If ever you are working on a document and all the text disappears, check the document name at the top of the screen. You may have accidentally pressed to create a new document! If this is the case, press to Close the new, unwanted, document.
Printing When you print on a PC in a University PC Facility managed by IT Services, your output is sent as a print job to a central print queue (one is for high quality black and white output which costs 5p per page, the other for colour printing which costs 30p per page). You have to log in to a Print Release Station (which is a separate computer) from where you can select which print job you want printed from the queue. Everyone has an initial credit of £1.50 in their print account, but you will need to purchase further top-up cards at £3 each in order to put more money into your print account when it is running low. The cards are available from the Reception Desk in the Main Library, the Agriculture Coffee Bar at Earley Gate and the Technical Support Unit at Bulmershe. You can also top up your account using cash via a facility in the Main Library. More detailed instructions on how to print are given in the Printing on IT Services PCs Quick Guide.

Set the required Page range and Number of copies: 4. The final step would normally be to click on [OK] but here, click on [Cancel] 23
It's a good idea to preview your work to check it fits neatly on the page before you print it. To do this: 5. Click on the [Office] button then move the mouse cursor over Print – a sub-menu appears: The image part with relationship ID rId174 was not found in the file.
6. From the further options that appear, choose Print Preview 7. Click on [Close print Preview] on the far right of the new Print Preview tab to return to normal typing Tip: It’s a good idea to add the [Print Preview] button to your Quick Access Toolbar.

This features an [Interactive Guide] button, which will show you how to issue a command in Word 2007 if you first carry out that command in a simulated version of Word 2003. The tab also has links to online training and can be downloaded from Microsoft if you have your own PC.

MICROSOFT EXCEL TUTORIAL GETTING STARTED Microsoft Excel is one of the most popular spreadsheet applications that helps you manage data, create visually persuasive charts, and thought‐provoking graphs. Excel is supported by both Mac and PC platforms. Microsoft Excel can also be used to balance a checkbook, create an expense report, build formulas, and edit them.
CREATING A NEW DOCUMENT OPENING MICROSOFT EXCEL ON A PC
To begin Microsoft Excel, Go to Start > All Programs > Applications > Microsoft Office > Microsoft Excel (Figure 1). When opened a new spreadsheet will pop up
on the screen, if this does not happen click on the Office Icon > New. From here a dialog box with various different templates will appear on the screen that you can choose from. Once a template is chosen, click Create.
Figure 1. Navigate to Microsoft Excel on a PC.
Figure 2. Opening a new workbook
SAVING YOUR DOCUMENT Computers crash and documents are lost all the time, so it is best to save often.
Before you begin you should save your document. To do this, click on the floppy disk located at the top of the screen . Then Microsoft Excel will open a dialog box (Figure 3) where you can specify the new file’s name, location of where you want it saved, and format of the document. Once you have specified a name, place, and format for your new file, press the Save button.
Note: Specifying your file format will allow you to open your document on a PC as well as a MAC. To do this you use the drop down menu next to the Format option. Also, when you are specifying a file extension (i.e. .doc) make sure you know what you need to use.
Figure 3. Saving dialog box.
SAVING LATER After you have initially saved your blank document under a new name, you can begin your project. However, you will still want to periodically save your work as insurance against a computer freeze or a power outage. To save, just click on the floppy disk, or for a shortcut press CTRL + S.
TOOLBARS In Microsoft Excel 2007 for a PC, the toolbars are automatically placed as tabs at the top of the screen. Within these tabs you will find all of your options to change text, data, page layout, and more. To be able access all of the certain toolbars you need to click on a certain tab that is located towards the top of the screen.
THREE COMMONLY USED TABS
The Home Tab: (Figure 4). This is one of the most common tabs used in Excel. You are able to format the text in your document, cut, copy, and paste information. Change the alignment of your data, insert, delete, and format cells. The Home Tab also allows you to change the number of your data (i.e. currency, time, date).
Figure 4. Home Tab.
The Insert Tab: (Figure 5). This tab is mainly used for inserting visuals and graphics into your document. There are various different things that can be inserted from this tab such as pictures, clip art, charts, links, headers and footers, and word art.
Figure 5. Insert Tab.
The Page Layout Tab: (Figure 6). Here you are able to add margins, themes to your document, change the orientation, page breaks, and titles. The scale fit of your document is also included as a feature within this tab, if needed.
Figure 6. Page Layout Tab.
FORMATTING WORKING WITH CELLS Cells are an important part of any project being used in Microsoft Excel. Cells hold all of the data that is being used to create the spreadsheet or workbook. To enter data into a cell you simply click once inside of the desired cell, a black border will appear around the cell (Figure 7). This border indicates that it is a selected cell. You may then begin typing in the data for that cell.
Figure 7. Entering Data.
CHANGING AN ENTRY WITHIN A CELL You may change an entry within a cell two different ways: • Click the cell one time and begin typing. The new information will replace any information that was previously entered. • Double click the cell and a cursor will appear inside. This allows you to edit certain pieces of information within the cells instead of replacing all of the data.
CUT, COPY, AND PASTE
You can use the Cut, Copy and Paste features of Excel to change the data within your spreadsheet, to move data from other spreadsheets into new spreadsheets, and to save yourself the time of re‐entering information in a spreadsheet. Cut will actually remove the selection from the original location and allow it to be placed somewhere else. Copy allows you to leave the original selection where it is and insert a copy elsewhere. Paste is used to insert data that has been cut or copied. To Cut or Copy:
Highlight the data or text by selecting the cells that they are held within. Go to the Home Tab > Copy (CTRL + C) or Home Tab > Cut (CTRL + X). Click the location where the information should be placed. Go to Home Tab > Paste (CTRL + V) to be able to paste your information.
FORMATTING CELLS There are various different options that can be changed to format the spreadsheets cells differently. When changing the format within cells you must select the cells that you wish to format.
To get to the Format Cells dialog box select the cells you wish to change then go to Home Tab > Format > Format Cells. A box will appear on the screen with six different tab options (Figure 8). Explanations of the basic options in the format dialog box are bulleted below.
Figure 8. Formatting Cells
Number: Allows you to change the measurement in which your data is used. (If your data is concerned with money the number that you would use is currency) Alignment: This allows you to change the horizontal and vertical alignment of your text within each cell. You can also change the orientation of the text within the cells and the control of the text within the cells as well. Font: Gives the option to change the size, style, color, and effects. Border: Gives the option to change the design of the border around or through the cells.
FORMATTING ROWS AND COLUMNS When formatting rows and columns you can change the height, choose for your information to autofit to the cells, hide information within a row or column, un‐hide the information. To format a row or column go to Home Tab > Row Height (or Column Height), then choose which height you are going to use (Figure 9). The cell or cells that are going to be formatted need to be selected before doing this. When
changing the row or column visibility (hidden, un‐hidden) or autofit, you will go to the Home Tab and click Format. The drop down menu will show these options The image part with relationship ID rId191 was not found in the file.
Figure 9. Formatting Rows and Columns Height
ADDING ROWS AND COLUMNS When adding a row or column you are inserting a blank row or column next to your already entered data. Before you can add a Row you are going to have to select the row that you wish for your new row to be placed. (Rows are on the left hand side of the spreadsheet) once the row is selected it is going to highlight the entire row that you chose. To insert the row you have to go to Home Tab > Insert > Insert Sheet Rows (Figure 10). The row will automatically be placed on the spreadsheet and any data that was selected in the original row will be moved down below the new row.
Figure 10. Inserting Rows
Before you can add a Column you are going to have to select a column on the spreadsheet that is located in the area that you want to enter the new column. (Columns are on the top part of the spreadsheet.) Once the column is selected it is going to highlight the entire row that you chose. To insert a column you have to go to Home Tab > Insert > Insert Sheet Column (Figure 11). The column will automatically be place on the spreadsheet and any data to the right of the new column will be moved more to the right.
Figure 11. Inserting Columns
WORKING WITH CHARTS Charts are an important part to being able to create a visual for spreadsheet data. In order to create a chart within Excel the data that is going to be used for it needs to be entered already into the spreadsheet document. Once the data is entered, the cells that are going to be used for the chart need to be highlighted so that the software knows what to include. Next, click on the Insert Tab that is located at the top of the screen. (Figure 12).
Figure 12. Charts Tab
You may choose the chart that is desired by clicking the category of the chart you will use. Once the category is chosen the charts will appear as small graphics within a drop down menu. To choose a particular chart just click on its icon and it will be placed within the spreadsheet you are working on. To move the chart to a page of its own, select the border of the chart and Right Click. This will bring up a drop down menu, navigate to the option that says Move Chart. This will bring up a dialog box that says Chart Location. From here you will need to select the circle next to As A New Sheet and name the sheet that will hold your chart. The chart will pop up larger in a separate sheet (Figure 13), but in the same workbook as your entered data.
The image part with relationship ID rId194 was not found in the file.
Figure 13. Chart in new sheet CHART DESIGN There are various different features that you can change to make your chart more appealing. To be able to make these changes you will need to have the chart selected or be viewing the chart page that is within your workbook. Once you have done that the Design Tab will appear highlighted with various different options to format your graphic (Figure 14). Figure 14. Design Tab for chart design.
CHART OPTIONS: Titles: To add titles to a chart of graphic you have to click on the Insert Tab. Once you have done this, click on the Text Box Icon. This will insert a text box that you can type the title and place anywhere you wish on the chart. Change Chart Type: You can change your chart easily by selecting this icon and navigating to a more desirable chart. This feature is very convenient for someone who chose the wrong chart and doesn’t wish to reselect all their data and go through the process a second time. Format Chart Area: This allows for changes to be made to the chards border, style, fill, shadows, and more. To get this option you will need to right click on the charts border and navigate to the Format Chart Area option. Once this is clicked a dialog box will appear.
CHART STYLE: Here you are able to change the color of the bars that are within your chart.
INSERTING SMART ART GRAPHICS PICTURES To insert Pictures: Go to the Insert Tab> Picture, a dialog box will appear and then you can select the desired picture from the location that is it stored (Figure 15). The picture will be inserted directly onto your document, where you can change the size of it as desired.
Figure 15. Inserting a picture
Inserting Clipart: To insert Clip Art you will need to go to the Insert Tab > Clip Art. A navigation pane will appear on the left hand side of the screen where you can search for words that pertain to the picture you are looking for.
Figure 16. Clip Art
CREATING FUNCTIONS When creating a function in Excel you must first have the data that you wish to perform the function with selected. • Select the cell that you wish for the calculation to be entered in (i.e.: if I want to know the sum of B1:B5 I will highlight cell B6 for my sum to be entered into) (Figure 17). • •
Figure 17. Choosing calculation cell Once you have done this you will need to select the Formulas Tab located at the top of the screen. A list of Most Recently Used, Financial, Logical, Text, Date and Time, Math and Trig formulas will appear. To choose one of the formulas click the icon that holds the formula you are looking for. Once you have clicked your formula this will display a dialog box on your screen. (Figure 18)
Figure 18. First calculation display
In this screen it lists the cells that are being calculated, the values within the cells, and the end result. •
To accept that calculation you can press OK and the result will show up in the selected cell.
PRINTING It is important to always save your document before you print!
To print your document, go to the Office Icon > Print, select your desired settings, and then click OK. You can also do this by using the shortcut CTRL + P
To be able to change the orientation of your page for printing you can click on the Properties button under the option to Print then click the Layout Tab (Figure 19).
Figure 19. Page Setup button and printing
OTHER HELPFUL FUNCTIONS UNDO AND REDO In order to undo an action, you can click on the blue arrow icon that is pointing to the left at the top of the screen. To redo an action, you can click on the blue arrow icon pointing to the right. It is important to note that not all actions are undoable, thus it is important to save before you make any major changes in your document so you can revert back to your saved document.
Before you quit, it's a good idea to save your document one final time. You will need to choose the Office Icon and choose Exit Excel. This is better than just closing the window, as it insures your document quits correctly.

Microsoft Access 2007 Introduction A database is a collection of information that's related. Access allows you to manage your information in one database file. Within Access there are four major areas: Tables, Queries, Forms and Reports • Tables store your data in your database • Queries ask questions about information stored in your tables • Forms allow you to view data stored in your tables • Reports allow you to print data based on queries/tables that you have created
Creating a Database 1) Start Access
2) Select Blank Database 3) In the File Name field enter a name for the database 4) Click Create
Microsoft Access automatically creates a new table in the database called Table1. This is a temporary name until the table is saved.
Understanding the Views There are 2 basic views when you work in a table: Design View and Datasheet View. Design View is used to set the data types, insert or delete fields, and set the Primary key. Datasheet View is used to enter the data for the records. By default, Access places you in Datasheet View. To Switch to Design view: 1) Click the View button on the Home Ribbon 2) Type a name for the table 3) Click OK
Before proceeding, it is important to understand common Microsoft Access Data Types. (Explained in the table below) The image part with relationship ID rId206 was not found in the file.
To Enter Fields in a Table: 1) Type a name for the first field in the table 2) Press Enter 3) Select a data type 4) Press Enter 5) Type a description for the field 6) Press Enter Continue this until all necessary fields have been entered into the table. Note: The order that you enter the field names is the order the fields will appear in the table and on a form. The image part with relationship ID rId207 was not found in the file.
To View the Datasheet: Click the View button on the Ribbon
Setting a Primary Key The Primary Key is the unique identifier for each record in a table. Access will not allow duplicate entries in a Primary Key field. By default, Access sets the first field in the table as the Primary Key field. An example of a Primary Key would be your Social Security Number. This is something unique about you and should not be duplicated. To Set a Primary Key: 1) Switch to Design View 2) Position your cursor in the field you wish to set as the Primary Key 3) Click the Primary Key button on the Ribbon
To Switch Back to Datasheet View to Enter your Records: Click the View button on the Ribbon.
Entering Data in a Table Once you have entered the fields and set the data types it is now time to enter the records in a table. To Enter Data in a Table: 1) Make sure you are in Datasheet View 2) Enter the data into the table by pressing the tab key to move from one cell to another 3) When you have completed the record (row), press Enter
The image part with relationship ID rId210 was not found in the file.
When inputting data into the table, Access automatically saves the data after each new record.
Input Masks An Input Mask is used to pre-format a field to “look/act” a certain way when a user inputs data. Example: You could create an input mask for a Social Security Number field that automatically inserts the dash. The Input Mask data can either be stored in the table or simply displayed and not stored. (The latter is preferred) To Create an Input Mask for a Field 1) Open a table in Design View 2) Click in a field for which you’d like to create an input mask 3) In the Field Properties section at the bottom of the screen, click in the Input Mask line and notice the Build button that appears at the right end of the line (see below) The image part with relationship ID rId211 was not found in the file.
4) Click the Build button 5) Select Input Mask 6) Click Next
7) Select a Placeholder character 8) Click Next The image part with relationship ID rId212 was not found in the file.
9) Select Without the symbols in the mask 10)Click Next 11)Click Finish The image part with relationship ID rId213 was not found in the file.
Now, when entering data that has been formatted with an Input Mask, you do not have to type the format into the record.
The following is an example of a table with a field that has been formatted with an Input Mask on the Social Security Field. Notice, the only thing that the user has to enter is the digits, not the symbols. The image part with relationship ID rId214 was not found in the file.
Navigating Records Use the arrows at the bottom of the table to navigate among records. You are able to navigate from the first record, previous record, next record, last record, and create a new record (as shown in the picture below). Notice that the total number of records in the table is shown at the right end of the navigation arrows. The image part with relationship ID rId215 was not found in the file.
Sorting Records in a Table By sorting your records in a table, you are easily able to view/locate records in your table. To Sort Records in a Table: 1) Position your cursor in the field that you wish to sort by, by clicking on any record in that field. 2) Click either the Sort Ascending or Sort Descending icon
Notice, the table above has been sorted by the Last Name field in ascending order.
Queries You use Queries to view, change, and analyze data in different ways. You can also use them as a source of records for forms and reports. To Create a Query: 1) Click the Create tab on the Ribbon 2) Click Query Design icon The image part with relationship ID rId216 was not found in the file.
3) 4) 5) 6)
Double-click Create Query in Design View Select the table that you would like to base your Query on Click Add Close the Show Table window
The table(s) will now be displayed in the upper part of the Query Design Screen by boxes containing the tables’ fields. 7) Double click on the field names in the field list window which you would like to include in the Query
Defining Criteria in the Query In order to control which records are displayed, you must define criteria in a Query. The most common type of Query is the Select Records Query which will be discussed below. To Define Criteria for your Query: 1) Position your cursor in the criteria row in the field for which you wish to define the criteria for 2) Enter the criteria Example: To find all people it the table who live in Edison:
• • •
Position your cursor in the criteria row of the City field Type Edison Click the Run Query button
Below is a picture of the results of the above query:
The image part with relationship ID rId217 was not found in the file.
The image part with relationship ID rId218 was not found in the file.
The result of a query is called a recordset. A recordset can be sorted, printed or filtered in the same manner as a table. To Save the Query: 1) Click the Save Icon 2) Enter a name for the Query 3) Click OK The image part with relationship ID rId219 was not found in the file.
Note: When saving a select Query, you are saving the question that you are asking, not the results that you see when you run the Query.
Creating a Form Using the Forms Wizard A form is a database object that is used to enter or display data in a database. To Create a Form Using the Wizard: 1) Navigate to the table you want to base the form on 2) Click Create on the Ribbon 3) Click Forms You are able to navigate using the navigation arrows at the bottom of the form. Note: The form feeds the table. If you edit a record on the form, or create a new record, that data will be passed to the table it is associated with. The image part with relationship ID rId220 was not found in the file.
To Enter a Record on the Form: 1) Click the View button on the Ribbon to switch from Layout View to Form View 2) Enter the data for each field in the record, pressing the Enter key to move to the next field 3) Press Enter after you have entered data for the last field This will send the record to the table.
Reports Reports can be based on tables or queries and can be made with the Report Wizard. To Create a Report Using the Report Wizard: 1) Click the Create tab on the Ribbon 2) Click the Report Wizard icon 3) Select the table or query upon which the report will be based 4) Select the fields that you want to include on the report by double clicking on them 5) Click Next 6) If you would like to add grouping to your report, select the field you wish to group by double clicking on it (Example: City) 7) Click Next 8) Select a style for the report 9) Click Next 10)Type a title for the report 11)Click Finish The image part with relationship ID rId221 was not found in the file.
To Print a Report 1) Open the report by double clicking on the object in the Navigation Pane 2) By default, the report opens in Print Preview. To Adjust the Orientation: Click the portrait or landscape icon on the Print Preview Ribbon To Adjust the Margins 1) Click them Margins icon on the Print Preview Ribbon 2) Select a margin size To Print the Report 1) Click the Print Icon on the Print Preview Ribbon 2) Select the Printer 3) Click OK

Basic Networking What is a computer Network? A network is any collection of independent computers that communicate with one another over a shared network medium. A computer network is a collection of two or more connected computers. When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives. When networks at multiple locations are connected using services available from phone companies, people can send e-mail, share links to the global Internet, or conduct video conferences in real time with other remote users. When a network becomes open sourced it can be managed properly with online collaboration software. As companies rely on applications like electronic mail and database management for core business operations, computer networking becomes increasingly more important. Every network includes:
• • •
At least two computers Server or Client workstation. Networking Interface Card's (NIC) A connection medium, usually a wire or cable, although wireless communication between networked computers and peripherals is also possible.
Network Operating system software, such as Microsoft Windows NT or 2000, Novell NetWare, Linux
Types of Networks: LANs (Local Area Networks) A network is any collection of independent computers that communicate with one another over a shared network medium. LANs are networks usually confined to a geographic area, such as a single building or a college campus. LANs can be small, linking as few as three computers, but often link hundreds of computers used by thousands of people. The development of standard networking protocols and media has resulted in worldwide proliferation of LANs throughout business and educational organizations.
WANs (Wide Area Networks) Wide area networking combines multiple LANs that are geographically separate. This is accomplished by connecting the different LANs using services such as dedicated leased phone lines, dial-up phone lines (both synchronous and asynchronous), satellite links, and data packet carrier services. Wide area networking can be as simple as a modem and remote access server for employees to dial into, or it can be as complex as hundreds of branch offices globally linked using special routing protocols and filters to minimize the expense of sending data sent over vast distances.
The Internet is a system of linked networks that are worldwide in scope and facilitate data communication services such as
With the meteoric rise in demand for connectivity, the Internet has become a communications highway for millions of users. The Internet was initially restricted to military and academic institutions, but now it is a full-fledged conduit for any and all forms of information and commerce. Internet websites now provide personal, educational, political and economic resources to every corner of the planet.
Intranet With the advancements made in browser-based software for the Internet, many private organizations are implementing intranets. An intranet is a private network utilizing Internet-type tools, but available only within that organization. For large organizations, an intranet provides an easy access mode to corporate information for employees.
MANs (Metropolitan area Networks) The refers to a network of computers with in a City.
VPN (Virtual Private Network) VPN uses a technique known as tunneling to transfer data securely on the Internet to a remote access server on your workplace network. Using a VPN helps you save money by using the public Internet instead of making long–distance phone calls to connect securely with your private network. There are two ways to create a VPN connection, by dialing an Internet service provider (ISP), or connecting directly to Internet.
Categories of Network: Network can be divided in to two main categories: •
Server – based.
In peer-to-peer networking there are no dedicated servers or hierarchy among the computers. All of the computers are equal and therefore known as peers. Normally each computer serves as Client/Server and there is no one assigned to be an administrator responsible for the entire network. Peer-to-peer networks are good choices for needs of small organizations here the users are allocated in the same general area, security is not an issue and the organization and the network will have limited growth within the foreseeable future.
The term Client/server refers to the concept of sharing the work involved in processing data between the client computer and the most powerful server computer.
The client/server network is the most efficient way to provide: • Databases and management of applications such as Spreadsheets, Accounting, Communications and Document management. •
Centralized file storage.
The client/server model is basically an implementation of distributed or cooperative processing. At the heart of the model is the concept of splitting application functions between a client and a server processor. The division of labor between the different processors enables the application designer to place an application function on the processor that is most appropriate for that function. This lets the software designer optimize the use of processors--providing the greatest possible return on investment for the hardware. Client/server application design also lets the application provider mask the actual location of application function. The user often does not know where a specific operation is executing. The entire function may execute in either the PC or server, or the function may be split between them. This masking of application function locations enables system implementers to upgrade portions of a system over time with a minimum disruption of application operations, while protecting the investment in existing hardware and software.
The OSI Model:
Open System Interconnection (OSI) reference model has become an International standard and serves as a guide for networking. This model is the best known and most widely used guide to describe networking environments. Vendors design network products based on the specifications of the OSI model. It provides a description of how network hardware and software work together in a layered fashion to make communications possible. It also helps with trouble shooting
function. There are seven to get familiar with and these are the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and the application layer. • Physical Layer, is just that the physical parts of the network such as wires, cables, and there media along with the length. Also this layer takes note of the electrical signals that transmit data throughout system. •
Data Link Layer, this layer is where we actually assign meaning to the electrical signals in the network. The layer also determines the size and format of data sent to printers, and other devices. Also I don't want to forget that these are also called nodes in the network. Another thing to consider in this layer is will also allow and define the error detection and correction schemes that insure data was sent and received.
Network Layer, this layer provides the definition for the connection of two dissimilar networks. Transport Layer, this layer allows data to be broken into smaller packages for data to be distributed and
Session Layer, this layer helps out with the task to carry information from one node (workstation) to another
addressed to other nodes (workstations). node (workstation). A session has to be made before we can transport information to another computer. •
Presentation Layer, this layer is responsible to code and decode data sent to the node. Application Layer, this layer allows you to use an application that will communicate with say the operation system of a server. A good example would be using your web browser to interact with the operating system on a server such as Windows NT, which in turn gets the data you requested.
Network Architectures: Ethernet
Ethernet is the most popular physical layer LAN technology in use today. Other LAN types include Token Ring, Fast Ethernet, Fiber Distributed Data Interface (FDDI), Asynchronous Transfer Mode (ATM) and LocalTalk. Ethernet is popular because it strikes a good balance between speed, cost and ease of installation. These benefits, combined with wide acceptance in the computer marketplace and the ability to support virtually all popular network protocols, make Ethernet an ideal networking technology for most computer users today. The Institute for Electrical and Electronic Engineers (IEEE) defines the Ethernet standard as IEEE Standard 802.3. This standard defines rules for configuring an
Ethernet network as well as specifying how elements in an Ethernet network interact with one another. By adhering to the IEEE standard, network equipment and network protocols can communicate efficiently.
Fast Ethernet For Ethernet networks that need higher transmission speeds, the Fast Ethernet standard (IEEE 802.3u) has been established. This standard raises the Ethernet speed limit from 10 Megabits per second (Mbps) to 100 Mbps with only minimal changes to the existing cable structure. There are three types of Fast Ethernet: 100BASE-TX for use with level 5 UTP cable, 100BASE-FX for use with fiber-optic cable, and 100BASE-T4 which utilizes an extra two wires for use with level 3 UTP cable. The 100BASE-TX standard has become the most popular due to its close compatibility with the 10BASE-T Ethernet standard. For the network manager, the incorporation of Fast Ethernet into an existing configuration presents a host of decisions. Managers must determine the number of users in each site on the network that need the higher throughput, decide which segments of the backbone need to be reconfigured specifically for 100BASE-T and then choose the necessary hardware to connect the 100BASE-T segments with existing 10BASET segments. Gigabit Ethernet is a future technology that promises a migration path beyond Fast Ethernet so the next generation of networks will support even higher data transfer speeds
Token Ring Token Ring is another form of network configuration which differs from Ethernet in that all messages are transferred in a unidirectional manner along the ring at all times. Data is transmitted in tokens, which are passed along the ring and viewed by each device. When a device sees a message addressed to it, that device copies the message and then marks that message as being read. As the message makes its way along the ring, it eventually gets back to the sender who now notes that the message was received by the intended device. The sender can then remove the message and free that token for use by others. Various PC vendors have been proponents of Token Ring networks at different times and thus these types of networks have been implemented in many organizations.
FDDI FDDI (Fiber-Distributed Data Interface) is a standard for data transmission on fiber optic lines in a local area network that can extend in range up to 200 km (124 miles). The FDDI protocol is based on the token ring protocol. In addition to being large geographically, an FDDI local area network can support thousands of users.
Protocols: Network protocols are standards that allow computers to communicate. A protocol defines how computers identify one another on a network, the form that the data should take in transit, and how this information is processed once it reaches its final destination. Protocols also define procedures for handling lost or damaged transmissions or "packets." TCP/IP (for UNIX, Windows NT, Windows 95 and other platforms), IPX (for Novell NetWare), DECnet (for networking Digital Equipment Corp. computers), AppleTalk (for Macintosh computers), and NetBIOS/NetBEUI (for LAN
network protocols in use today. Although each network protocol is different, they all share the same physical cabling. This common method of accessing the physical network allows multiple protocols to peacefully coexist over the network media, and allows the builder of a network to use common hardware for a variety of protocols. This concept is known as "protocol independence," Some Important Protocols and their job:

Introduction to TCP/IP Networks: TCP/IP-based networks play an increasingly important role in computer networks. Perhaps one reason for their appeal is that they are based on an open specification that is not controlled by any vendor.
What Is TCP/IP? TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. The term TCP/IP is not limited just to these two protocols, however. Frequently, the term TCP/IP is used to refer to a group of protocols related to the TCP and IP protocols such as the User Datagram Protocol (UDP), File Transfer Protocol (FTP), Terminal Emulation Protocol (TELNET), and so on.
The Origins of TCP/IP In the late 1960s, DARPA (the Defense Advanced Research Project Agency), in the United States, noticed that there was a rapid proliferation of computers in military communications. Computers, because they can be easily programmed, provide flexibility in achieving network functions that is not available with other types of communications equipment. The computers then used in military communications were manufactured by different vendors and were designed to interoperate with computers from that vendor only. Vendors used proprietary protocols in their communications equipment. The military had a multi vendor network but no common protocol to support the heterogeneous equipment from different vendors
Net work Cables and Stuff: In the network you will commonly find three types of cables used these are the, coaxial cable, fiber optic and twisted pair.
Thick Coaxial Cable This type cable is usually yellow in color and used in what is called thicknets, and has two conductors. This coax can be used in 500-meter lengths. The cable itself is made up of a solid center wire with a braided metal shield and plastic sheathing protecting the rest of the wire.
Thin Coaxial Cable As with the thick coaxial cable is used in thicknets the thin version is used in thinnets. This type cable is also used called or referred to as RG-58. The cable is really just a cheaper version of the thick cable.
Fiber Optic Cable As we all know fiber optics are pretty darn cool and not cheap. This cable is smaller and can carry a vast amount of information fast and over long distances.
Twisted Pair Cables These come in two flavors of unshielded and shielded.
Shielded Twisted Pair (STP) Is more common in high-speed networks. The biggest difference you will see in the UTP and STP
the STP use's metallic shield wrapping to protect the wire from interference. -Something else to note about these cables is that they are defined in numbers also. The bigger the number the better the protection from interference. Most networks should go with no less than a CAT 3 and CAT 5 is most recommended.
Now you know about cables we need to know about connectors. This is pretty important and you will most likely need the RJ-45 connector. This is the cousin of the phone jack connector and looks real similar with the exception that the RJ-45 is bigger. Most commonly your connector are in two flavors and this is BNC (Bayonet Naur Connector) used in thicknets and the RJ-45 used in smaller networks using UTP/STP.
Unshielded Twisted Pair (UTP) This is the most popular form of cables in the network and the cheapest form that you can go with. The UTP has four pairs of wires and all inside plastic sheathing. The biggest reason that we call it Twisted Pair is to protect the wires from interference from themselves. Each wire is only protected with a thin plastic sheath.
Ethernet Cabling Now to familiarize you with more on the Ethernet and it's cabling we need to look at the 10's. 10Base2, is considered the thin Ethernet, thinnet, and thinwire which uses light coaxial cable to create a 10 Mbps network. The cable segments in this network can't be over 185 meters in length. These cables connect with the BNC connector. Also as a
10Base5, this is considered a thicknet and is used with coaxial cable arrangement such as the BNC connector. The good side to the coaxial cable is the high-speed transfer and cable segments can be up to 500 meters between nodes/workstations. You will typically see the same speed as the 10Base2 but larger cable lengths for more versatility. 10BaseT, the “T” stands for twisted as in UTP (Unshielded Twisted Pair) and uses this for 10Mbps of transfer. The down side to this is you can only have cable lengths of 100 meters between nodes/workstations. The good side to this network is they are easy to set up and cheap! This is why they are so common an ideal for small offices or homes. 100BaseT, is considered Fast Ethernet uses STP (Shielded Twisted Pair) reaching data transfer of 100Mbps. This system is a little more expensive but still remains popular as the 10BaseT and cheaper than most other type networks. This on of course would be the cheap fast version. 10BaseF, this little guy has the advantage of fiber optics and the F stands for just that. This arrangement is a little more complicated and uses special connectors and NIC's along with hubs to create its network. Pretty darn neat and not to cheap on the wallet. An important part of designing and installing an Ethernet is selecting the appropriate Ethernet medium. There are four major types of media in use today: Thickwire for 10BASE5 networks, thin coax for 10BASE2 networks, unshielded twisted pair (UTP) for 10BASE-T networks and fiber optic for 10BASE-FL or Fiber-Optic Inter-Repeater Link (FOIRL) networks. This wide variety of media reflects the evolution of Ethernet and also points to the technology's flexibility. Thickwire was one of the first cabling systems used in Ethernet but was expensive and difficult to use. This evolved to thin coax, which is easier to work with and less expensive.
Network Topologies: What is a Network topology? A
are three topology's to think about when you get into networks. These are the star, rind, and the bus.
Star, in a star topology each node has a dedicated set of wires connecting it to a central network hub. Since all traffic passes through the hub, the hub becomes a central point for isolating network problems and gathering network statistics. Ring, a ring topology features a logically closed loop. Data packets travel in a single direction around the ring from one network device to the next. Each network device acts as a repeater, meaning it regenerates the signal Bus, the bus topology, each node (computer, server, peripheral etc.) attaches directly to a common cable. This topology most often serves as the backbone for a network. In some instances, such as in classrooms or labs, a bus will connect small workgroups
Collisions: Ethernet is a shared media, so there are rules for sending packets of data to avoid conflicts and protect data integrity. Nodes determine when the network is available for sending packets. It is possible that two nodes at different locations attempt to send data at the same time. When both PCs are transferring a packet to the network at the same time, a collision will result. Minimizing collisions is a crucial element in the design and operation of networks. Increased collisions are often the result of too many users on the network, which results in a lot of contention for network bandwidth. This can slow the performance of the network from the user's point of view. Segmenting the network, where a network is divided into different pieces joined together logically with a bridge or switch, is one way of reducing an overcrowded network.
Ethernet Products: The standards and technology that have just been discussed help define the specific products that network managers use to build Ethernet networks. The following text discusses the key products needed to build an Ethernet LAN.
Transceivers Transceivers are used to connect nodes to the various Ethernet media. Most computers and network interface cards contain a built-in 10BASE-T or 10BASE2 transceiver, allowing them to be connected directly to Ethernet without requiring an external transceiver. Many Ethernet devices provide an AUI connector to allow the user to connect to any media type via an external transceiver. The AUI connector consists of a 15-pin D-shell type connector, female on the computer side, male on the transceiver side. Thickwire (10BASE5) cables also use transceivers to allow connections.
For Fast Ethernet networks, a new interface called the MII (Media Independent Interface) was developed to offer a flexible way to support 100 Mbps connections. The MII is a popular way to connect 100BASE-FX links to copper- based Fast Ethernet devices
Network Interface Cards:
Network interface cards, commonly referred to as NICs, and are used to connect a PC to a network. The NIC provides a physical connection between the networking cable and the computer's internal bus. Different computers have different bus architectures; PCI bus master slots are most commonly found on 486/Pentium PCs and ISA expansion slots are commonly found on 386 and older PCs. NICs come in three basic varieties: 8-bit, 16-bit, and 32- bit. The larger the number of bits that can be transferred to the NIC, the faster the NIC can transfer data to the network cable.
Many NIC adapters comply with Plug-n-Play specifications. On these systems, NICs are automatically configured without user intervention, while on non-Plug-n-Play systems, configuration is done manually through a setup program and/or DIP switches Cards are available to support almost all networking standards, including the latest Fast Ethernet environment. Fast Ethernet NICs are often 10/100 capable, and will automatically set to the appropriate speed. Full duplex networking is another option, where a dedicated connection to a switch allows a NIC to operate at twice the speed.
Hubs/Repeaters: Hubs/repeaters are used to connect together two or more Ethernet segments of any media type. In larger designs, signal quality begins to deteriorate as segments exceed their maximum length. Hubs provide the signal amplification required to allow a segment to be extended a greater distance. A hub takes any incoming signal and repeats it out all ports.
Ethernet hubs are necessary in star topologies such as 10BASE-T. A multi-port twisted pair hub allows several pointto-point segments to be joined into one network. One end of the point-to-point link is attached to the hub and the other is attached to the computer. If the hub is attached to a backbone, then all computers at the end of the twisted pair segments can communicate with all the hosts on the backbone. The number and type of hubs in any onecollision domain is limited by the Ethernet rules. These repeater rules are discussed in more detail later.
Adding Speed: While repeaters allow LANs to extend beyond normal distance limitations, they still limit the number of nodes that can be supported. Bridges and switches, however, allow LANs to grow significantly larger by virtue of their ability to support full Ethernet segments on each port. Additionally, bridges and switches selectively filter network traffic to only those packets needed on each segment - this significantly increases throughput on each segment and on the overall network. By providing better performance and more flexibility for network topologies, bridges and switches will continue to gain popularity among network managers.
Bridges: The function of a bridge is to connect separate networks together. Bridges connect different networks types (such as Ethernet and Fast Ethernet) or networks of the same type. Bridges map the Ethernet addresses of the nodes residing on each network segment and allow only necessary traffic to pass through the bridge. When a packet is received by the bridge, the bridge determines the destination and source segments. If the segments are the same, the packet is dropped ("filtered"); if the segments are different, then the packet is "forwarded" to the correct segment. Additionally, bridges
Bridges are also called "store-and-forward" devices because they look at the whole Ethernet packet before making filtering or forwarding decisions. Filtering packets, and regenerating forwarded packets enable bridging technology to split a network into separate collision domains. This allows for greater distances and more repeaters to be used in the total network design.
Ethernet Switches: Ethernet switches are an expansion of the concept in Ethernet bridging. LAN switches can link four, six, ten or more networks together, and have two basic architectures: cut-through and store-and-forward. In the past, cut-through
switches were faster because they examined the packet destination address only before forwarding it on to its destination segment. A store-and-forward switch, on the other hand, accepts and analyzes the entire packet before forwarding
It takes more time to examine the entire packet, but it allows the switch to catch certain packet errors and keep them from propagating through the network. Both cut-through and store-and-forward switches separate a network into collision domains, allowing network design rules to be extended. Each of the segments attached to an Ethernet switch has a full 10 Mbps of bandwidth shared by fewer users, which results in better performance (as opposed to
hubs that only allow bandwidth sharing from a single Ethernet). Newer switches today offer high-speed links, FDDI, Fast Ethernet or ATM. These are used to link switches together or give added bandwidth to high-traffic servers. A network composed of a number of switches linked together via uplinks is termed a "collapsed backbone" network.
Routers: Routers filter out network traffic by specific protocol rather than by packet address. Routers also divide networks logically instead of physically. An IP router can divide a network into various subnets so that only traffic destined for particular IP addresses can pass between segments. Network speed often decreases due to this type of intelligent forwarding. Such filtering takes more time than that exercised in a switch or bridge, which only looks at the Ethernet address. However, in more complex networks, overall efficiency is improved by using routers.
What is a network firewall? A firewall is a system or group of systems that enforces an access control policy between two networks. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of mechanisms: one which exists to block traffic, and the other which exists to permit traffic. Some firewalls place a greater emphasis on blocking traffic, while others emphasize permitting traffic. Probably the most important thing to recognize about a firewall is that it implements an access control policy. If you don't have a good idea of what kind of access you want to allow or to deny, a firewall really won't help you. It's also important to recognize that the firewall's configuration, because it is a mechanism for enforcing policy, imposes its policy on everything behind it. Administrators for firewalls managing the connectivity for a large number of hosts therefore have a heavy responsibility.
Network Design Criteria: Ethernets and Fast Ethernets have design rules that must be followed in order to function correctly. Maximum number of nodes, number of repeaters and maximum segment distances are defined by the electrical and mechanical
A network using repeaters, for instance, functions with the timing constraints of Ethernet. Although electrical signals on the Ethernet media travel near the speed of light, it still takes a finite time for the signal to travel from one end of a large Ethernet to another. The Ethernet standard assumes it will take roughly 50 microseconds for a signal to reach its
Ethernet is subject to the "5-4-3" rule of repeater placement: the network can only have five segments connected; it can only use four repeaters; and of the five segments, only three can have users attached to them; the other two must
If the design of the network violates these repeater and placement rules, then timing guidelines will not be met and the sending station will resend that packet. This can lead to lost packets and excessive resent packets, which can slow network performance and create trouble for applications. Fast Ethernet has modified repeater rules, since the minimum packet size takes less time to transmit than regular Ethernet. The length of the network links allows for a
fewer number of repeaters. In Fast Ethernet networks, there are two classes of repeaters. Class I repeaters have a latency of 0.7 microseconds or less and are limited to one repeater per network. Class II repeaters have a latency of 0.46 microseconds or less and are limited to two repeaters per network. The following are the distance (diameter) characteristics for these types of Fast Ethernet repeater combinations:
Fast Ethernet No
One Class I Repeater One Class II Repeater Two
* Full Duplex Mode 2 km
When conditions require greater distances or an increase in the number of nodes/repeaters, then a bridge, router or switch can be used to connect multiple networks together. These devices join two or more separate networks, allowing network design criteria to be restored. Switches allow network designers to build large networks that function well. The reduction in costs of bridges and switches reduces the impact of repeater rules on network design. Each network connected via one of these devices is referred to as a separate collision domain in the overall network.
Types of Servers: Device Servers A device server is defined as a specialized, network-based hardware device designed to perform a single or specialized set of server functions. It is characterized by a minimal operating architecture that requires no per seat network operating system license, and client access that is independent of any operating system or proprietary protocol. In addition the device server is a "closed box," delivering extreme ease of installation, minimal maintenance, and
Print servers, terminal servers, remote access servers and network time servers are examples of device servers which are specialized for particular functions. Each of these types of servers has unique configuration attributes in hardware or software that help them to perform best in their particular arena.
Print Servers Print servers allow printers to be shared by other users on the network. Supporting either parallel and/or serial interfaces, a print server accepts print jobs from any person on the network using supported protocols and manages those
Print servers generally do not contain a large amount of memory; printers simply store information in a queue. When the desired printer becomes available, they allow the host to transmit the data to the appropriate printer port on the server. The print server can then simply queue and print each job in the order in which print requests are received, regardless of protocol used or the size of the job.
Multiport Device Servers Devices that are attached to a network through a multiport device server can be shared between terminals and hosts at both the local site and throughout the network. A single terminal may be connected to several hosts at the same time (in multiple concurrent sessions), and can switch between them. Multiport device servers are also used to network devices that have only serial outputs. A connection between serial ports on different servers is opened, data
Given its natural translation ability, a multi-protocol multiport device server can perform conversions between the protocols it knows, like LAT and TCP/IP. While server bandwidth is not adequate for large file transfers, it can easily handle host-to-host inquiry/response applications, electronic mailbox checking, etc. And it is far more economical than the alternatives of acquiring expensive host software and special-purpose converters. Multiport device and print servers
Whether it is moving printers and other peripherals from one network to another, expanding the dimensions of interoperability or preparing for growth, multiport device servers can fulfill your needs, all without major rewiring.
Access Servers While Ethernet is limited to a geographic area, remote users such as traveling sales people need access to networkbased resources. Remote LAN access, or remote access, is a popular way to provide this connectivity. Access servers use telephone services to link a user or office with an office network. Dial-up remote access solutions such as ISDN or asynchronous dial introduce more flexibility. Dial-up remote access offers both the remote office and the remote user the economy and flexibility of "pay as you go" telephone services. ISDN is a special telephone service that offers three channels, two 64 Kbps "B" channels for user data and a "D" channel for setting up the connection. With ISDN, the B channels can be combined for double bandwidth or separated for different applications or users. With asynchronous remote access, regular telephone lines are combined with modems and remote access servers to allow users and networks to dial anywhere in the world and have data access. Remote access servers provide connection points for both dial-in and dial-out applications on the network to which they are attached. These hybrid devices route and filter protocols and offer other services such as modem pooling and terminal/printer services. For the remote PC user, one can connect from any available telephone jack (RJ45), including those in a hotel rooms or on most airplanes.
Network Time Servers A network time server is a server specialized in the handling of timing information from sources such as satellites or radio broadcasts and is capable of providing this timing data to its attached network. Specialized protocols such as NTP or udp/time allow a time server to communicate to other network nodes ensuring that activities that must be
coordinated according to their time of execution are synchronized correctly. GPS satellites are one source of information that can allow global installations to achieve constant timing.
IP Addressing: An IP (Internet Protocol) address is a unique identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number usually represented as 4 decimal values, each representing 8 bits, in the range 0 to 255 (known
10001100.10110011.11011100.11001000 Every IP address consists of two parts, one identifying the network and one identifying the node. The Class of the address and the subnet mask determine which part belongs to the network address and which part belongs to the node address.
Address Classes: There are 5 different address classes. You can determine which class any IP address is in by examining the first 4 bits
Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine. [You can test this: you should always be able to ping 127.0.0.1, which points to yourself] Class D addresses are reserved for multicasting. Class E addresses are reserved for future use. They should not be used for host addresses. Now we can see how the Class determines, by default, which part of the IP address belongs to the network (N) and which
In the example, 126.96.36.199 is a Class B address so by default the Network part of the address (also known as the Network Address) is defined by the first two octets (140.179.x.x) and the node part is defined by the last 2 octets (x.x.220.200). In order to specify the network address for a given IP address, the node section is set to all "0"s. In our example, 188.8.131.52 specifies the network address for 184.108.40.206. When the node section is set to all "1"s, it specifies a broadcast that is sent to all hosts on the network. 220.127.116.11 specifies the example broadcast address. Note that this is true regardless of the length of the node section.
Private Subnets: There are three IP network addresses reserved for private networks. The addresses are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They can be used by anyone setting up internal IP networks, such as a lab or home LAN behind a NAT or proxy server or a router. It is always safe to use these because routers on the Internet will never forward packets
Subnetting an IP Network can be done for a variety of reasons, including organization, use of different physical media (such as Ethernet, FDDI, WAN, etc.), preservation of address space, and security. The most common reason is to control network traffic. In an Ethernet network, all nodes on a segment see all the packets transmitted by all the other nodes on that segment. Performance can be adversely affected under heavy traffic loads, due to collisions and the resulting retransmissions. A router is used to connect IP networks to minimize the amount of traffic each segment must receive.
Subnet Masking Applying a subnet mask to an IP address allows you to identify the network and node parts of the address. The network bits are represented by the 1s in the mask, and the node bits are represented by the 0s. Performing a bitwise logical AND operation between the IP address and the subnet mask results in the Network Address or Number. For
Default subnet masks: Class
CIDR was invented several years ago to keep the internet from running out of IP addresses. The "classful" system of allocating IP addresses can be very wasteful; anyone who could reasonably show a need for more that 254 host addresses was given a Class B address block of 65533 host addresses. Even more wasteful were companies and organizations that were allocated Class A address blocks, which contain over 16 Million host addresses! Only a tiny percentage of the allocated Class A and Class B address space has ever been actually assigned to a host computer on
People realized that addresses could be conserved if the class system was eliminated. By accurately allocating only the amount of address space that was actually needed, the address space crisis could be avoided for many years. This
The use of a CIDR notated address is the same as for a Classful address. Classful addresses can easily be written in CIDR
It is currently almost impossible for an individual or company to be allocated their own IP address blocks. You will simply be told to get them from your ISP. The reason for this is the ever-growing size of the internet routing table. Just 5 years ago, there were less than 5000 network routes in the entire Internet. Today, there are over 90,000. Using CIDR, the biggest ISPs are allocated large chunks of address space (usually with a subnet mask of /19 or even smaller); the ISP's customers (often other, smaller ISPs) are then allocated networks from the big ISP's pool. That way, all the big ISP's customers (and their customers, and so on) are accessible via 1 network route on the Internet. It is expected that CIDR will keep the Internet happily in IP addresses for the next few years at least. After that, IPv6, with 128 bit addresses, will be needed. Under IPv6, even sloppy address allocation would comfortably allow a billion unique IP addresses for every person on earth
Examining your network with commands: Ping PING is used to check for a response from another computer on the network. It can tell you a great deal of information
Ping returns different responses depending on the computer in question. The responses are similar depending on the options Ping
.It takes its name from a submarine sonar search - you send a short sound burst and listen for an echo - a ping coming
In an IP network, `ping' sends a short data burst - a single packet - and listens for a single packet in reply. Since this tests the most basic function of an IP network (delivery of single packet), it's easy to see how you can learn a lot from some
To stop ping, type control-c. This terminates the program and prints out a nice summary of the number of packets transmitted, the number received, and the percentage of packets lost, plus the minimum, average, and maximum round-trip
meikro$ The Time To Live (TTL) field can be interesting. The main purpose of this is so that a packet doesn't live forever on the network and will eventually die when it is deemed "lost." But for us, it provides additional information. We can use the TTL to determine approximately how many router hops the packet has gone through. In this case it's 255 minus N hops, where N is the TTL of the returning Echo Replies. If the TTL field varies in successive pings, it could indicate that
milliseconds. In general, it's best if round-trip times are under 200 milliseconds. The time it takes a packet to reach its destination is called latency. If you see a large variance in the round-trip times (which is called "jitter"), you are going to see poor performance talking to the host
NSLOOKUP NSLOOKUP is an application that facilitates looking up hostnames on the network. It can reveal the IP address of a host or,
It is very important when troubleshooting problems on a network that you can verify the components of the networking process. Nslookup allows this by revealing details within the infrastructure.
NETSTAT NETSTAT is used to look up the various active connections within a computer. It is helpful to understand what computers or networks you are connected to. This allows you to further investigate problems. One host may be responding well but another may be less responsive.
IPconfig This is a Microsoft windows NT, 2000 and xp command. It is very useful in determining what could be wrong with a network. This command when used with the /all switch, reveal enormous amounts of troubleshooting information within the system.

What is the Internet?
The Internet is a network for computers. It connects computers all over the world. People make their own websites. These websites have domains, which is an address. You type in the address to get to the right domain. Most addresses start with www. This stands for the World Wide Web. There are many, many websites. Some are owned and updated by government agencies, companies, schools and medical groups. Some people make money from their websites and others just post websites or web pages for fun or information.

Why Use the Internet? The Internet has become a very important part of our world. Many employees now have workplace email and most employers want to hire workers who know how to use the Internet. More and more people are choosing to share messages and pictures through email and social networks (such as Facebook and Twitter). Using the Internet can also save time, money and effort. For example: Using email and social websites is a less expensive way of staying in touch with family and friends, especially if they live far away. Banking online saves time because you do not have to write cheques or stand in line at your local bank. The Internet is a quick way to find information, such as local weather, phone numbers and postal codes. The Internet is helpful when looking and applying for jobs. Most employers post job ads online. Stores, government agencies and organizations now have websites. These sites have lists of Frequently Asked Questions (FAQs). You may access these sites to get the answers to your questions without having to phone for information. This cuts down the time you spend waiting on hold.

Learn How to Type Fast The ability to type quickly, accurately and without seeing at the keyboard is a huge advantage beside the nature of your work at computer system. Having good typing skills is essential in today’s society where almost everything is computer based and hence requires typing on a keyboard to input texts and messages frequently . 1. Fast touch typing can save a lot of time at school and colleges when taking notes, writing assignments and chatting with friends online. 2. In the workplace, people who type quick have a natural edge to get more things done and win the acceptance. 3. If you likes chatting and communicates forums, typing fast will save you a lot of time and allow you to say more. 4. For journalists, blogger and writers, skilled typing abilities will help you in your day to day job. 5. For secretaries and administrators, typing is a fundamental job requirement. This is also true for a range of other typing related jobs such as for data entry operators and LDC.
Touch Typing Touch typing is typing without looking at the keyboard. The idea is to teach your fingers the location of each keys. Typing Speed is measured in Words Per Minute (WPM), commonly used in typing test examination and recruitment. For the purposes of WPM measurement a word is standardized to five characters or keystrokes. Therefore, “write” counts as one word, but “understand” counts as two words and blank space also count as one character.
Tips for increasing your typing speed Body Posture :
This is the basic of learning the typing skills. You have to sit straight with a comfortable height of the chair from where you can see to your monitor. Your end of the palm must be grounded to the end of the keyboard or surface where your keyboard is placed. Place your fingers correctly on the keyboard. Never try to type with your fingertips or nails.
Placement of fingers on Keyboard : The F and J keys have a raised bar or a dot allowing your finger to identify them. Once you have placed your two indexes on those keys, the other fingers are placed on the keys next to them. 'A' 'S' 'D' 'F' and 'J' 'K' 'L' ';' are the base positions for your fingers. Your fingers go from the base position to the key that you want to press and after pressing the key it backs at base position. In order to type fast you have to be careful about which finger to use to press a key. Take a look at the drawing below.
Each color match a finger. For example the right index is pink and has to type only the pink keys. Always try to type with both hands. Divide groups in the keyboard for both hands. Always use thumb of any hand for press the space bar.
Memorize the position of Keys : To become a good typist you have to memorize the keyboard and create a mental map of the associated fingers. You have to be able to press any key without even thinking. For example if I say 'E' you have to think move the middle finger up and press 'E' instantly. You can only achieve this through practice. You have to build up the muscle memory of each finger.
You can type with much more speed without seeing to the keyboard. It is very easy if you practice daily for it. In initial few days let there be mistakes in typing but don't look towards keyboard, instead try to remember the keys.
Use of Shortcut Keys :
Shortcut keys are very handy for computer users. Shortcuts keys help provide an easier and usually quicker method of navigating and using computer applications. While writing content you can easily format the text if you make use of shortcut keys, which will save your further time of formatting the document. Maximize use of keyboard shortcut's instead of using mouse because when you move your hand form keyboard to mouse and again set's to the right key position consumes much time.
Practice makes man perfect :
Without practice no one can be a good typist. Try to give an hour daily as practice session for Typing. You can use IndiaTyping for practice. IndiaTyping will show you real time accuracy, speed statics and it never allows you go further without type correct character for your typing speed improvement.
Key ideas 1) Place your indexes on 'F' and 'J'. 2) Use same finger all time to type each key. 3) Don't look at the keyboard, your eyes should always look at the screen
We all know that typing speed matters. Whether you’re applying for a job as a paralegal or an executive assistant, being able to type quickly and accurately might be the only skill that stands between you and another equally qualified applicant. Can you type 65+ words per minute? If you didn’t have the benefit of taking a typing course or two in school, that might not be the case. So, how do you get those skills up to par in a short period of time so that you can compete for these high paying positions? Here’s 5 shortcuts that will help you increase your typing speed in no time. We don’t guarantee overnight results but, if you follow these tips you’ll definitely get a leg up on the competition.
Technique Matters Touch typing is 80% technique, 10% accuracy and 10% speed. People who are masters at touch typing will tell you that without proper hand position and typing technique, you’ll only be able to type so fast. Think about it, there is no way that the person using the hunt and peck method will ever be as fast as someone who uses proper technique on a QWERTY keyboard. Using the proper technique will make learning to type much easier and open a world of opportunities when it comes to increasing typing speed.
Errors are Opportunities for Improvement When you first start learning to touch type, you’re going to make some errors. In fact you might make a lot of them. Your success really depends on how you view making those mistakes – do you see them as a failure or as an opportunity to improve? People who see their mistakes as an opportunity to improve generally learn faster than people who don’t. Your mindset plays a big part in how quickly you learn and how much information you are able to take in.
Repetition Never Gets Boring Touch typing is all about muscle memory, which means that your muscles will need some time to adjust to the new techniques that you are learning. The best and quickest way to do this is through repetition. By doing the same exercise over and over you will be able to ingrain those movements into your muscle memory. If you are using an online typing tutor, set a high standard for yourself. Make a decision to master a technique 100% before moving on to the next lesson.
This may seem more time consuming upfront but, if you do this the subsequent lessons will be easier since they are built upon the techniques taught in the previous lessons.
Good Posture Can Work Wonders Posture is one of the most overlooked factors when it comes to learning to type quickly. Poor posture not only takes a toll on your muscles, but can affect your energy levels and accuracy as well. Good posture while typing will keep up your energy levels and also allow your fingers to rest in the correct position. Keeping correct posture allows you to type faster, more accurately and will help prevent injury. The correct posture to have while typing is relaxed with feet squarely on the floor and wrists level with the keyboard.
Don’t Look at the Keyboard Another great trick to help you increase your typing speed in a short period of time is to avoid looking at the keyboard. Initially, this may result in more mistakes, but you will learn the positions of the keys at a much higher rate without using the keyboard as a crutch. Because it can be tempting to simply look down at the keyboard, try covering the keyboard and your hands with a piece of paper while you type. Or, if you really want to challenge your self, Das Keyboard Ultimate is a keyboard with blank keys that will literally force you to learn the keys via motor-skills.
Practice, Practice, Practice… Finally, the best way to increase your typing speed is through good old practice. While practice isn’t necessarily a shortcut and requires dedicated effort, it really is the best way to see results. Even if you practice your typing skills for 30 minutes each day for a month, you will see an improvement that can make all the difference in helping you land your dream job.
SAFETY SIGNS & COLOUR AT WORK Objectives: At the end of this unit, you will be able to know and understand: •
State the common causes for accidents
State the functions of signboards
Part of the four basic categories of safety signboards
Give examples of each category of sign boards.
1.1 CAUSES FOR ACCIDENTS Accidents happen due to causes which cannot be foreseen. Most accidents are a result of human error, ignorance, neglect, forgetfulness or recklessness. Most accidents can be prevented. Normally accidents do not just happen. They are caused. Causes for accidents are many, some of the important ones are: · - Un-awareness of danger
- Disregard for safety - Negligence - Lack of understanding of proper safety procedures - Untidy condition of workplace - Inadequate light and ventilation - Improper use of tools 1.2 SAFE ATTITUDES People's attitudes govern what they do or fail to do. In most cases accidents occur when someone is working with unsafe equipment or in an unsafe situation. These situations which cause accidents because the working person has failed to do certain things. Most accidents do not just happen. Accidents are caused by those who, for example, damage equipment or find that it is facility but don't set it right or at least report it to the concerned people. Anybody who sees a hazard and does nothing about it is contributing to the possibility of an accident. Knowing the possibility of an accident if a worker does not bother about it that by itself is enough to ensure a workman is crippled for life. He might not have caused the accident, but could have definitely prevented it. 1.3 SAFETY SIGNS AND COLOUR AT WORK Safety signs and colour are useful tools to help protect the health and safety of employees and workplace visitors. Safety signs are used to:
• • • • • •
Draw attention to health and safety hazards Point out hazards that may not be obvious Provide general information and directions Remind employees where personal protective equipment must be worn Show where emergency equipment is located Indicate where certain actions are prohibited
Colour attracts attention and can be used extensively for safety purposes. For example, colour can be used as an additional safety measure to identify the contents of pipes and the nature of the hazard. The choice of colour also draws attention to the probability of a hazard causing harm. For example, the colour red is used to indicate a definite hazard. A potential hazard is communicated by the colour yellow. When employees are aware of the hazards around them and take the necessary precautions, the possibility of an injury, illness or other loss is minimized. However while safety signs and colours are valuable in warning of hazards, they are not substitutes for eliminating or reducing those hazards, whenever possible. This guideline will help your workplace to effectively use safety signs and colours for the protection of employees and visitors alike. 1.4 SIGN CATEGORIES
As shown in the table below, there are three basic sign categories used in the workplace: Each category is distinguished by its shape. These categories are divided into sub-categories that can be recognized by their colour. Regulatory • Warning • Information Each category is distinguished by its shape. These categories are divided into sub-categories that can be recognized by their colour 1.5 SIGN TYPES One of three sign types should be used to communicate a message: • Symbol signs • Symbol signs with text • Text signs Use symbols that are simple and easy to learn and recognize. Include simple wording (text) to help explain the meaning of the symbol or to provide more information. Text signs should only be used when no appropriate symbols exist. Check the CSA international standard CAN/CSA Z321-96 to see if the topic or message you want to convey is listed. Examples of the three types of signs are shown below, based on the CSA standard.

SAFE LIFTING AND CARRYING TECHNIQUES 3.1: CAUSES OF INJURY A majority of the accidents reported while working, involve injuries caused while lifting and carrying loads. Wrong lifting techniques will result in injury to the person as well as damaging the load. Wrong lifting techniques can result in injury even when the load lifted is not heavy. When a load is lifted without following the correct technique, the muscles and joints get strained. The most common type of injury due to the wrong way of lifting is injury to the back. Another cause for injuries during lifting and carrying may be, because of tripping over an object and falling, or striking an object with the load 3.2. TYPES OF INJURY AND METHODS TO PREVENT THEM
Figure 3.1 Cuts and abrasions Cuts and abrasions are caused: •
By rough surfaces and jagged edges
By splinters and sharp or pointed projections as shown in Figure 3.1
To avoid cuts and abrasions to hands, leather gloves should be worn for protection. But while lifting large or heavy loads, body contact may be involved which must be avoided. Crushing of feet or hands The feet or hands should be positioned so that they cannot be trapped by the load. Timber wedges can be used when raising and lowering heavy loads to ensure the fingers and hands are not caught and crushed. To avoid crushing of feet, safety shoes with steel toe caps as shown in Figure 3.2 should be used
Figure 3.2 Strains to muscles and joints Strains to muscles and joints may be the result of: •
lifting a load which is too heavy, or
Sudden and awkward movements such as twisting or jerking during a lift can put severe strain on muscles. Injury to the back is most often caused by lifting loads which are either too heavy or by employing a wrong method of lifting. Lifting from a standing position (stoop lifting) with the back rounded as shown in Fig increases the chances of back injury This method must, therefore, be avoided. The human spine is not an efficient weight lifting machine and can get easily damaged if incorrect load lifting techniques are used The stress on a rounded back can be up to six times greater than it is when the spine is kept straight. 3.3. POINTS THAT MAKE AN OBJECT/LOAD, DIFFICULT TO CARRY Although weight is a factor which makes it difficult to carry an object, it is not the only factor. This is because, if the size and shape of an object is awkward to handle, it becomes more difficult to carry such loads than it is to carry heavy loads of easy-to-handle and of small size. This is because, the load which requires the arms to be extended in front of the body, gives more strain on the back and stomach than a compact object carried close to the body. Shown in figure 3.3
The absence of handles as natural handling points can also make it difficult to raise and carry objects. •
The weight a person can lift also depends on the age, physique and his experience in lifting and handling heavy loads
3.4. PREPARATION BEFORE LIFTING OR SHIFTING HEAVY LOADS A load which seems light enough to carry at first, will become progressively heavier the farther you have to carry it. Hence it is advised not to be over confident. Before lifting or shifting a load, get answers to the following questions •
Is the load heavy?
Wherefrom and whereto should the load be moved?
Can you handle it atone or do you need assistance?
Before lifting and carrying a load make sure that the route in which you are going to carry the load is clear of obstacles and is stable and not slippery. Before carrying a load, make sure that the place where the load has to deposited/placed is clear and stable. Be ore carrying a load, make a trial lift to ensure that you are able to see around and over the load when you are carrying it. 3.5. CORRECT BODY POSTURE BEFORE BEGINNING THE LIFT IN KINETIC METHOD OF LIFTING • FEET- Place your feet about 18 inches (45cms) apart, with one foot slightly forward, in the direction of movement. This gives a good balance and provides a secure basis for lifting. • • • • •
KNEES- Slightly bends your knees (but NOT fully bent as in a squat). BACK - Keep your back straight, although the body may be inclined forward. ARMS - Keep your arms as close in to the body as possible. The further the arms are extended the greater the strain. Elbows too should be kept in. GRIP- Ensure that the grip on the load for lifting is firm and secure. HEAD- Keep your head erect with the chin in
3.6. MANUAL LIFTING TECHNIQUE USING KINETIC METHOD • Approach the load. Stand erect and facing the direction of travel. Keep your feet 18 to 20 inches wide apart. Place one feet slightly forward. • Sit in a squatting position with your legs slightly apart. And the load to be lifted held close to the body. Hold the load at its handles or it natural safe grip points. • Before lifting keep your back as straight as possible. Straighten your legs. Look directly ahead. • Slightly lean back and raise the upper part of the body to the vertical position, while lifting the load. • Keeping the load touching your body. Carry to the place where it is to be placed. If you have to make a turn while carrying, turn the whole body in one movement. • Bend at the knees to a semi-squatting position. Keep the back and head erect and look straight.
Lower the load slightly and rest your elbows on the thighs to rest. Place the load smoothly without jerks on surface.
3.8. SHIFTING OF WORKING TABLES • Before shifting, finalize the place where the table has to be shifted. • Confirm that the new-place is free from obstacles and the ground is stable. • Clear the travel way so that the table could be moved freely without damaging any objects on its way. • Disconnect all electrical connections made to the table. • Remove tools, equipments, if any, from the table. • Depending on the size and weight of the table take the assistance of one or more persons. • Make sure that the height of the person(s) assisting you is more or less the same as your height to ensure balanced lifting and shifting. • Make your assistant(s) hold the table at suitable grip points and at intervals suitable to balance the load when lifted. • Lift the table simultaneously at all positions to a height of 3 to 4 inches above the ground level. • Travel simultaneously towards the destination point carrying the table slowly and without losing the grip. • While carrying the load, keep your back as straight as possible and look straight. • Place the table slowly and simultaneously at its destination. • Make necessary electrical connections. 3.8.SHIFTING OF ELECTRONIC EQUIPMENTS/INSTRUMENTS • Disconnect the electrical connections and other external prods/wires. • Take care to prevent damages to the knobs and controls during lifting and transporting. • Get yourself familiar with the load and weight distribution inside by lifting them up by few inches from its place. • Lift the equipment at its handle/grip points. • Carry the equipment holding it close to your body and walk slowly to its destination. • Place the equipment gently over the surface without any jerk. 3.9. BASIC STEPS OF SAFE LIFTING AND HANDLING • Size up the load and check overall conditions. Don't attempt the lift by yourself if the load appears to be too heavy or awkward. Check that there is enough space for movement, and that the footing is good. "Good housekeeping" ensures that you won't trip or stumble over an obstacle. • Make certain that your balance is good. Feet should be shoulder width apart, with one foot beside and the other foot behind the object that is to be lifted. • Bend (he knees; don't stoop. Keep the back straight, but not vertical. (There is a difference. Tucking in the chin straightens the back.) • Grip the load with the palms of your hands and your fingers. The palm grip is much more secure. Tuck in the chin again to make certain your back is straight before starting to lift. • Use your body weight to start the load moving, then lift by pushing up with
• • • •
the legs. This makes full use of the strongest set of muscles. Keep the arms and elbows close to the body while lifting. Carry the load close to the body. Don't twist your body while carrying the load. To change direction, shift your foot position and turn your whole body. Watch where you are going! To lower the object, bend the knees. Don't stoop. To deposit the load on a bench or shelf, place it on the edge and push it into position. Make sure your hands and feet are clear when placing the load.
Make it a habit to follow the above steps when lifting anything-even a relatively light object. 3.10.TEAM LIFTING MUST BE COORDINATED • If the weight, shape, or size of an object makes the job too much for one person, ask for help. •
Ideally, workers should be of approximately the same size for team lifting.
One individual needs to be responsible for control of the action to ensure proper coordination. If one worker lifts too soon, shifts the load, or lowers it improperly, either they or the person working with them may be injured.
Walk out of step
3.11.LIFTING HEAVY OBJECTS • Safe lifting of heavy items requires training and practice. For example, we've probably all seen a small person move heavy feed sacks with apparent ease. •
The secret lies in taking the proper stance and grip.
When equipment is available, it should be used to lift and carry heavy objects.
Loaders, forklifts, hoists, etc. are made for this purpose.
3.12. DO’S" AND "DON'TS" OF SAFE LIFTING AND CARRYING Do Don't Tuck in the chin to keep the back as straight as possible while lifting.
Use your back muscles to do lifting. Try to lift an item that is too heavy of Awkward.
Lift with the strong leg muscles.
Twist your body while carrying an object.
Ask for help with the heavy, awkward Attempt team lifting items. without proper coordination. When possible, use mechanical equipment to move heavy items.

FIRE AND FIRE EXTINGUISHERS OBJECTIVES: On completion of this lesson you shall be able to : • State the effects of a fire break out • State the conditions required for combustion relevant to fire prevention • State the general precautionary measures to be taken for fire prevention • Determine the correct type of fire extinguisher required for a particular function. • State the meaning of electric shock • State the factors that determine the severity of a shock • State the severity of shock based on the voltage level 4.1. FIRE Fire is nothing but burning of a combustible material. For combustion the three main requirements are shown in Figure 4.1
Figure 4.1 4.2. Fuel Fuel can be any combustible substance in the form of a solid, liquid or gas. Examples; wood, paper, petrol, kerosene, LPG etc., The fuel will catch fire and burn provided a high enough temperature(heat) is brought about and a continuous supply of oxygen is given. It is important to note that without fuel; combustion cannot take place. 4.3. HEAT Fuels will begin to burn at a certain temperature. Different types of fuels need different temperatures to catch fire and burn. For example, wood needs a higher temperature to catch fire and burn than paper. Petrol needs much lesser temperature to catch fire and burn than Paper. Generally liquid fuels give off vapor when heated. It is this vapor which ignites. Some liquids such as
Petrol do not have to be heated as they give off vapor at room temperature (15°C - 25°C} itself. It is important to note that without heat, fuel cannot get ignited (catch fire) and hence combustion cannot take place 4.4. OXYGEN Oxygen exists in air. The amount of oxygen in air is sufficient to continue the combustion once it occurs. Hence to keep a fire burning, oxygen is a must. It is important to note that without oxygen, combustion can- not continue to take place. · 4.5. CONTROLLED AND UNCONTROLLED FIRE Fire is a boon to mankind. Without fire, there would not be cooked food or hot water for bath as and when we want it. At the same time if the fire does not get constrained to a place of requirement, fire can become a bane (curse) to. mankind An uncontrolled fire .can cause such a disaster Which not only leads to destruction of material but also endanger the life of persons, hence, the lesson one must never forget is, keep the fire under control. Every effort must be made to prevent uncontrolled fire. When there is a fire outbreak, it must be controlled and extinguished immediately without any delay. 4.6. PREVENTING FIRE The majority of fires begin with small outbreaks. If this is not noticed, fire goes out of control and will be on its way of destruction. Hence, most fires could be prevented if suitable care is taken by following some simple common sense rules as given below • Do not accumulate combustible refuse such as cotton waste, waste or cloth soaked with oil, scrap wood, paper, etc. in odd corners. These refuse should be in their collection bins or points • Do not misuse or neglect electrical equipments or electrical wiring as this may cause electrical fire. Loose connections, low rated fuses, overloaded circuits causes over heating which may in turn lead to fire. Damaged insulation between conductors in cables cause electrical short circuit and cause fire. • Keep away clothing and other materials which might catch fire from heating appliances. Make sure the soldering iron is disconnected from power supply and is kept safe in its stand at the end of the working day. • Store highly flammable liquids and petroleum mixtures such as thinner, adhesive solutions, solvents, kerosene, spirit, LPG gas etc. in the storage area exclusively meant for storage of flammable materials. • Turn off blowlamps and torches when they are not in use. 1.

4.7 CONTROLLING AND EXTINGUISHING FIRE Isolating or removing any of three factors illustrated in Fig , will control and extinguish fire. There are three • basic ways of achieving this. • Starving the fire of fuel To remove the fuel which is burning or cut further supply of fuel to the fire. • Smothering To stop the supply of oxygen to the fire by blanketing the fire with foam, sand etc. • Cooling To reduces the temperature of the fire by spraying water and thus cooling the fire. By any one of the above three methods, fire can be first controlled and then extinguished. For the purpose of determining the best method of extinguishing different types of fires, fires are classified under four main classes based on the type of fuel as given in Table Classification of Fire
Class A Fire
Wood, paper cloth etc. Solid materials
Precautions and extinguishing Most effective method is cooling with water. Jets of water should be sprayed on the base
Class B Fire
Flammable liquids & liquefiable solids
Should be smothered. The aim. is to cover the entire surface of the burning liquid. This has the effect of cutting off the supply of oxygen to the fire. Water should never be used on burning liquids Foam, dry powder or C02 may be used on this type of fire
Class C Fire
Gas and liquefied gas
Extreme caution is necessary in dealing with liquefied gases. There is a risk of Explosion and sudden outbreak of fire in the entire vicinity. If an appliance fed from a cylinder catches fire shut off the supply of gas. The safest course is to raise an alarm and leave the fire to be dealt with by trained personnel.
Dry powdered extinguishers are used on this type of fire. Class D Fire
The standard range of fire extinguishing agents is inadequate or dangerous when . dealing with metal fires. Fire in electrical equipment: Carbon dioxide, dry powder, and vaporizing liquid(CTC) extinguishers can be used to Deal with fires in electrical equipment. Foam or liquid (e.g. water) extinguishers must not be used on electrical equipment at all.
4.8. FIRE EXTINGUISHERS Different fire extinguishing agents should be used for different types of fires as listed in Table Using a wrong type of extinguishing agent can make things worse. A fire extinguishing agent is the material or substance used to put out the fire. These extinguishing materials are usually (but not always) contained in a container called the 'fire extinguisher' with a mechanism for spraying into the fire when needed. There is no classification for electrical fires as such as these are only fires in materials where electricity is present. To control electrical fire in a building the electrical supply should be cut off first. 4.9TYPES OF FIRE EXTINGUISHERS Many types of fire extinguishers are available with different extinguishing agents to deal with different classes of fires as shown in Figure 4.2 Always check the operating instructions on the extinguisher before use
Figure 4.2 4.9.1.Water-filled extinguishers In water-filled extinguishers, as shown in Fig 4.3 there are two types based on the method of operating the extinguisher. a) Cartridge type b) Stored pressure type
Figure 4.3 A) GAS CATRIDGE TYPE (B) STORED PRESSURE TYPE In both the methods of operation, the discharge can be interrupted as required. This is to conserve the contact area and to prevent unnecessary damage to the material due to water. 4.9.2.Foam extinguishers
These may be stored pressure or gas cartridge types as shown in Figure 4.4
Figure 4.4 Most suitable for: •
Flammable liquid fires
Running liquid fires.
Not to be used in fires where electrical equipment is. Involved.
4.9.3. Dry powder extinguishers Extinguishers fitted with dry powder may be of the gas cartridge or stored pressure type as shown in Figure 4.5 Appearance and the method of operation is the same as that of water-filled one. The main distinguishing feature is the fork-shaped nozzle. Powders have been specially developed to deal with Class D fires
Figure 4.5 4.9.4. Carbon dioxide (C02) This type is easily distinguished by the distinctively shaped discharge horn as shown in Figure 4.6 . These extinguishers are suitable for fires on flammable liquids and liquefiable solids. Best suited where contamination by deposits must be avoided. Not generally effective in the open air
Figure 4.6 4.9.5. Halon Extinguishers Carbon tetrachloride (CTC) and Bromochlorodinuoromethane (BCF). They may be either gas cartridge or nonconductive. Shown in figure 4.7
Figure 4.7 The fumes given off these extinguishers are dangerous especially in confined space. 4.10. GENERAL PROCEDURE TO BE ADOPTED IN THE EVENT OF A FIRE • Raise a loud alarm by using any of the following. Adopt any one method of giving an alarm signal for fire breaking in your institute/ workshop.
o Raising your voice and shouting Fire! Fire! Fire! ... To call the attention of others. o Running towards the fire shouting Fire! Fire! and actuate fire alarm/bell/siren. This alarm/bell/siren. to be actuated only in case of fire.
o Any other means by which the attention of others can be called and are made to understand there is a fire break out. •
On receipt of _the fire alarm signal, do the following:
stop the normal work you are doing
turn off the power for all machinery and equipments
switch off fans/air circulators/exhaust fans
Switch off the mains if accessible.
If you are not involved in fire o
evacuate the working premises
close the doors and windows, but do bolt
assemble at a safe open place along with the others
If you in the room/place where the fire has broken out, leave the place calmly through the emergency exit.
If you are involved in the fire fighting team, o
Take instructions/give instructions for an organized way of fighting the fire. If you are taking instructions
Follow the instructions systematically. Do not panic.
Do not get trapped in fire or smoke in a hurry.
If you are giving instructions,
Assess the class of fire (class A,B,C or D)
Send for sufficient assistance and fire brigade
Judge the magnitude of the fire. Locate locally available suitable means to put-out the fire.
Ensure emergency exit paths are clear of obstructions. Attempt to evacuate the people and explosive materials, substances that can serve as further fuel for fire within the vicinity of the fire break.
Allot clear activity to person’s involved in firefighting by name to avoid confusion.
Control and extinguish the fire using the right type of fire extinguisher and making use of the available assistance effectively.
After fully extinguishing the fire, make a report of the fire accident and the measures taken_ to put out the fire, to the authorities concerned.
HAZARD IDENTIFICATION, RISK ASSESSMENT AND RISK CONTROL 5.2.1Introduction Employers have a duty to ensure, as far as practicable; that employees are not exposed to hazards at the workplace. There is a specific requirement for employers to carry out a risk management process. It involves a three-step process to: •
Assess risks; and
To assist in carrying out the risk management process, consideration should be given to: •
Previous injuries, ‘near miss’ incidents or accidents which have occurred at the workplace or other similar workplaces;
Relevant codes of practice and guidance notes;
Consultation with employees, safety and health representatives (if any) and safety and health committees to find out any problems associated with performing tasks or jobs;
Encouraging employees to report work-related injury or illness symptoms;
Walk-through inspections of the workplace. Consider using checklists; and
Records or statistics that could indicate potentially unsafe work practices.
5.2.2. Identifying Hazards The first step in the risk management process is identifying hazards. This involves recognizing items that may cause injury or harm to the health of people. There are a number of ways to identify items or potential situations that may cause an injury or harm. Choosing an appropriate process or procedure for identifying hazards will depend on the nature of the work environment and hazards involved. Hazard identification processes or procedures may include: •
Developing a hazard checklist;
Examining records of past incidents and injuries at the workplace;
Examining data for similar workplaces;
Carrying out inspections of the workplace (consider using checklists);
Consulting relevant codes of practice and guidance notes;
Encouraging employees to report work-related symptoms;
Consulting employees and safety and health representatives and committees (if any); and
Talking to industry associations and other similar businesses.
A hazard identification process or procedure may range from simple checklists for specific equipment, such as workstations, to a more open-ended appraisal of a group of related work processes. Generally, a combination of methods will provide the most effective results. 5.2.3. Common hazards at office The safety and health hazards at office may include (but are not limited to): •
An inadequate physical working environment increasing the risk of injury or harm;
Inadequate workstations increasing the risk of muscle and soft tissue injuries;
inadequate work organization increasing the risk of muscle and soft tissue injuries, as well as work-related stress symptoms and fatigue including vocal and visual fatigue;
Acoustic incidents and background noise increasing the risk of an acoustic injury occurring; and
Inadequate headset hygiene increasing the risk of infection.
These hazards can be associated with overcrowding, poor workstation design, non-adjustment of workstations to suit the individual, repetitive work, work overload (such as when demand suddenly increases), insufficient ‘time out’, abusive customers, long spread of hours, faulty telephone equipment, hot disking and sharing headsets 5.2.4Controlling Risks The third step is to implement control measures to eliminate or reduce the risk of people being injured or harmed and ensure the measures are monitored and reviewed on an ongoing basis. There is a preferred order of control measures ranging from the most effective to the least effective in eliminating or reducing the risks of injury or harm. This is outlined in the following manner. •
Elimination — removing the hazard or hazardous work practice from the workplace. For example:
Modifying workstation design;
Modifying work organization with task analysis and job redesign;
Modifying work shifts;
Replacing faulty equipment; and
Preventing mobile phones being used inside the office.
Substitution — substituting or replacing a hazard or hazardous work practice with a less hazardous one.
For example, replacing equipment and workstations with better designed ones. •
Isolation — isolating or separating the hazard or hazardous work practice from people involved in the work or people in the general work area. For example: o
Locating fax machines in specifically designated areas away from employees; and
Ensuring noisy work areas, such as printers and photocopiers, are located away from employees.
Engineering controls — if the hazard cannot be eliminated, substituted or isolated, an engineering control is the next preferred measure. For example: o
Repairing and maintaining equipment;
Promptly repairing network faults;
Installing acoustic shock prevention devices in telephone sets;
Reducing background noise levels;
Providing more space between operators/operator groups or installing acoustic barriers; and
Adjusting lighting to reduce glare.
Administrative controls — this includes introducing work practices that reduce the risk, such as implementing measures to ensure procedures, instruction and training are provided,
For example: o
Implementing acoustic incident reporting and action plans;
Implementing or improving customer contact and dispute resolution procedures; and
Implementing job rotation.
5.3. Workstation Layout and ergonomic Guideline 5.3.1Signs and symptoms of injury You may notice pain, numbness, tingling, or weakness while on the job. Sometimes these sensations are signs and symptoms of musculoskeletal injury (MSI). Other times, they are just part of the normal human condition, and can be ignored. Signs and symptoms may be associated with: •
Awkward postures (for example neck bent forward or wrist bent backward)
Static postures (holding body parts in one position for extended periods of time)
The risk of injury increases the longer you perform repetitive movements or work with awkward or static postures. The risk of injury also increases if more than one of these factors is present while you are working. Signs and symptoms of injury may appear suddenly, or they may appear gradually over a period of weeks, months, or years. Sometimes signs or symptoms are worse when you move in certain ways at work or at home. We all experience discomfort in our lives at work and at home. Some discomfort may be relieved by adjusting your workstations. Symptoms may indicate certain conditions such as those affecting muscles, nerves, and tendons. Consider the following examples:
Muscles are prone to fatigue and strain when overworked.
Compression of a nerve by inflamed surrounding tissue can cause Irritation.
Recurring irritation of tendons can lead to tendinitis or tenosynovitis.
5.3.2. Aches and Pains
5.3.3Suggested Workstation Dimensions and adjustment Ranges
5.3.4. Adjust your chair The chair position may be uncomfortable for you as a result of one or more of the following: •
Seating that doesn’t adequately support your back may increase fatigue and contribute to poor posture.
Seating that is too high or too low may result in symptoms in your neck, shoulders, back, or legs.
Seating that is too low may require you to use awkward arm postures to reach up to the work surface, or may cause you to sit with your knees raised, increasing the stress on your lower back.
Sitting for long periods without varying your posture increases fatigue.
When you begin to feel discomfort, you may have held a position too long. Avoid fatigue and discomfort by varying your posture regularly throughout the workday. You can do this by adjusting your chair and standing or walking occasionally. Your chair controls should be simple to use so it’s easy for you to adjust your chair, while seated, regularly during the workday 5.3.5.Rearrange your workstation layout. Your computer workstation should be arranged so that you can use comfortable postures when working with the monitor, keyboard, mouse, documents, and other items.
Monitors If you work with a computer, you should have your eyes tested about every two years, or more frequently if you are experiencing problems with your vision. Keeping your screen at the optimal height and viewing distance will help prevent or reduce eye strain and muscle tension in your neck, shoulders, and upper back. Screen height The top line of text on your computer screen (not the top of the monitor) should be at eye level, as shown on page 6. Most of the screen will be slightly below eye level. If you don’t have an adjustable monitor support, adjust the monitor height by placing stable, stackable materials underneath the monitor to bring the top of the screen to eye level. An adjustable monitor support is handy if you share a workstation because it makes adjusting the height of the monitor quick and easy. Viewing distance The distance between your eyes and the screen when sitting in a typing position should be about arm’s length. Your ears should be in line with your shoulders when you view the monitor. Prescription eyewear Eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Prescription lenses can be made to maximize vision and comfort when working at a computer, either as glasses specifically for computer use or as bifocal or multifocal glasses. To determine your visual needs for working with a monitor, your ophthalmologist or optometrist will need the following information: •
Measurements from your eyes to the monitor screen, work documents, and keyboard — for more accuracy, have someone else take these measurements.
The size of the screen — Measure diagonally across the screen, and add on approximately 2–3 cm (1 in.).
A description of your job tasks — Describe your daily routine at the computer and how much time you spend each day at different tasks.
A description of the programs used — Mention whether you use text or graphics programs, and describe typical type sizes and screen background colours.
Type of lighting — describe the lighting you work under (for example, natural light, fluorescent light, or lights under a cupboard or shelf).
Dual monitors Consider the following when setting up a dual-monitor workstation: •
Place both monitors at the same optimal height as for a single monitor.
Make sure both monitors are no closer than arm’s length away to avoid excess neck rotation. If necessary, increase the font size so you can place each monitor at least an arm’s length away from you.
Position your main monitor so it is straight in front of you and in line with your keyboard and chair. Position your second monitor right next to the main monitor.
If you use both monitors equally, place them side by side and adjust your body, keyboard, and mouse so your body and neck are straight.
Increase your mouse speed to reduce the amount of movement required to move the cursor across both screens.
Keyboards If your keyboard is adjusted properly, you will be able to keep your wrists straight while typing. This is a posture that may decrease the potential for injury. To obtain the optimal keyboard height, follow these guidelines: •
Adjust the keyboard surface up or down so that your wrists are straight
When your fingers are on the middle row of keys.
If your keyboard surface doesn’t adjust this way, raise or lower your chair until you can hold your wrists straight while touching the middle row of keys. Your work surface should be just below your elbows, and your forearms should be parallel to the floor, with your elbows at your sides.
You can also make a slight adjustment to the keyboard angle and height by folding the small legs, found on the underside of most keyboards, in or out. In most cases, you will need to keep the legs folded in to keep the keyboard flat and prevent bending of your wrists. Palm or wrist supports Do you tend to drop your palms or wrists while typing? If so, you could develop sore wrists. A palm or wrist support can provide support during rest periods from typing. When typing, do not rest on the support. Rest your wrists occasionally when you stop typing or mousing, by placing your palms (not your wrists) on the support. The support should be similar in thickness to your keyboard and narrow in depth so that it only touches the palm, not the wrist. It should be made of a soft, smooth, rounded material.
Don’t bend your wrists up (as illustrated) or down while typing.
If your wrists are straight while typing, you decrease the risk of injury. The mouse and other pointing devices Like your keyboard, if your mouse or other pointing device is at the proper height, you will be able to keep your wrists straight, shoulders relaxed, and elbows by your sides. This is typically a comfortable position that may decrease your risk of injury. The mouse Consider the following guidelines for using a mouse: •
Keep your mouse at the same height and as close to your keyboard as is practical. Don’t reach further than necessary to use your mouse. Move it closer, if possible, or use the mouse in your opposite hand.
Some computer furniture doesn’t provide enough room to place the mouse in the preferred position — you may have to get an extension to the keyboard surface for your mouse. Make sure you have enough space to move the mouse freely.
Keep your wrist straight while using the mouse. Avoid bending your wrist back or to either side. Use a full arm motion from the shoulder when guiding the mouse.
Relax your hand over the mouse. Don’t hold it too tightly.
Take your hand off the mouse when you are not using it.
If you are experiencing discomfort in your hand or wrist, try increasing the mouse’s pointer speed.
If you are having difficulties with your mouse, consider these options:
Use the mouse with your non-dominant hand.
Move the mouse closer to you.
Use a keyboard that has the number pad on the left side, or one without a number pad.
Use a different type of pointing device. Shown in figure 5.5
Figure 5.5 Don’t bend your wrist from side to side while using the mouse. Instead, try to move your whole arm to keep your wrist straight Other pointing devices Other pointing devices such as styluses, tablets, and trackballs should also be within a comfortable reach if you use them often or for long periods of time. These devices are often used by graphic artists, draftsmen, engineers, and others involved in specialized computer work such as computer-aided drawing. Keep your wrists straight and your upper body relaxed when using these devices. To obtain the optimal working posture for using a pointing device, follow these guidelines: •
Adjust the work surface up or down so that your wrists are straight when you are using it.
If your work surface doesn’t adjust this way, raise or lower your chair until you can hold your wrists straight
5.3.6.Laptops or notebook computers Laptop or notebook computers can be very convenient because they can take up less room and are easier to transport than conventional desktop computers. However, laptops can be more difficult to adjust to allow for good working postures. Consider using separate components (peripherals) when you are using your laptop computer at your workstation. For example, you can use the laptop screen as your monitor, and attach an external keyboard and mouse. Using separate components allows each one to be independently adjusted. If you have visual difficulties, plugging the laptop in to a larger external monitor may be helpful. If you are unable to use external components, consider the tasks you will be working on, and adjust your laptop accordingly: •
When reading lengthy documents, raise the screen to eye level to avoid bending your head downward.
When typing intensively, lower the keyboard so that your elbows just clear the top of the work surface, your arms are by your sides with about a 90-degree angle at the elbow, and your wrists are straight.
Take a break from your laptop. Do other jobs that don’t involve using a computer. It is better to take several short breaks, where you can change your posture, rather than one long break.
Multi-user and multi-task workstations Workstations used by more than one person or for a variety of tasks should be height adjustable. If you work at a multi-user or multi-task workstation, you should be able to adjust it quickly to suit you and the
task at hand. Adjustable workstation components such as monitor stands, keyboard supports, and work surfaces allow you to do this. Adjustable chairs and footrests are key components for multi-user workstations — they help each user obtain the optimal working height. You should also receive training in how to adjust the equipment and how to determine the correct posture for different tasks Documents Poor placement of the documents you look at while typing may lead to muscle discomfort or eye strain.
Figure 5.6 Poor placement of documents while typing can lead to awkward postures To reduce the need for these movements, place the documents as close as possible to the screen, with the documents at the same height and viewing distance as the screen. See “Placement of documents.” If your work is mostly data input, move the monitor to one side and place the document in front of you, at the same height and viewing distance as the monitor. If the document is too heavy or large for a standard document holder, you can improve the viewing angle and distance by using a binder or some other object on your desk to prop the document up. You can also purchase stands designed for large documents. Placement of documents: If you need to look back and forth from the screen to the documents, place your hard copy on a document holder, close to and at the same height and viewing distance as the monitor. Shown in figure 5.7
Figure 5.7 For data input, move the monitor to one side and place the documents in front of you 5.3.7.Exercises to reduce muscle tension and eye strain Daily stretching exercises aren’t a substitute for a proper workstation or equipment, or a cure for persistent pain or discomfort. However, they can help reduce muscle tension and eye strain. The stretches described in this section take about five minutes to complete. Repeat each stretch three to five times. You can do all of these exercises or select specific ones to relieve tension in particular muscles or areas of your body. If you do an exercise that stretches one side of the body, you should also do it on your other side to balance your exercise routine. Before starting to exercise, see your health care provider if you have a medical condition or injury in a part of the body involved in any of the exercises Body Part
Exercise or Stretch
Squeeze your shoulder blades together with your elbows lifted away from your body. Imagine you have a pencil between your shoulder blades and you are trying to trap it and then release it.
Hold your arms straight in front of you, and stretch them forward. Raise your arms above your shoulders, and stretch them upward.
Sit relaxed, feet flat on the floor. Imagine a cable attached to the top of your head pulling you up. Hold for a count of three, and then relax. Repeat three times
Clench your fists, then release them, spreading out your fingers. Hold each position for a count of three.
In a sitting or standing posture, drop your arms to your side. Gently shake out your arms and hands.
Lift your lower leg from a seated posture, leaving your knee bent slightly. Rotate your
Wrists and hands
ankle slowly. Point your toes and then pull them toward your shin. • QUESTIONNAIRE:

MANAGING HEALTH AND SAFETY AT WORK OBJECTIVES: On completion of this lesson you shall be able to: •
How to prevent from office accidents
Layout of your office for safe working
Controlling hazards in your office
Action plan taking in emergency
6.1. INTRODUCTION Historically, the office has been considered a relatively safe and healthy place to work. Increasingly, however, office workers have expressed concerns about the office environment and their working conditions. These concerns are also reflected in complaints of discomfort, anxiety, irritation and general job dissatisfaction and can be measured in terms of sick leave, absenteeism and job turnover. This chapter discusses major areas of concern related to health and safety in the office. Accidents that occur in offices are frequently due to poorly designed office environments and improper office procedures. The rate of office accidents declines when office workers are informed of potential hazards and safe work practices. Training regarding general safety precautions for work in an office reduces both the number and severity of accidents. Office workers are increasingly sensitive to the effects of computer video display terminals (VDTs) upon their health and safety. Individuals who use computers with VDTs commonly report stress-related and musculoskeletal disorders. If such disorders are to be reduced, computer workstations must accommodate the needs of office workers. Concern over air quality in offices has generated various health-related symptoms that are known collectively as the “sick building syndrome.” Indoor air pollution and inadequate ventilation are presently subjects of intense study. The ambience of interoffice surroundings has caused problems for office workers. Such factors as improper temperature, inadequate humidity, and even colors of walls and furnishings are now known to be sources of discomfort. These are situations that should be considered in creating a safety, healthful and efficient office environment. 6.2. GENERAL OFFICE SAFETY Concern for safety is not a typical concern for the office worker because the office is not generally perceived as a hazardous environment. As this book shows, potential safety hazards do exist in the office and, if not corrected, can result in decreased productivity and possible serious injury. 6.3. TYPES OF OFFICE ACCIDENTS The most common office accident is falling. Falls account for the greatest number of disabling injuries. They result in the most severe injuries and the highest percentage of lost workdays due to such injuries.
Falls from chairs occur when workers lean back to tilt their chairs, place their feet on a desk, sit down without looking, and rise from or move around in a chair. Falls on stairs also occur, but more precaution is usually exercised on stairs because the fall hazard they pose is recognized. Slips, trips and falls can result from poor housekeeping such as wet sur- faces, electrical cords improperly placed and walkways obstructed by trash. Falls also occur when workers stand on chairs or other office furniture to reach elevated objects. Injuries from strain and overexertion frequently occur when office workers attempt to move or improperly lift heavy objects. Office workers sustain muscular and back injuries by carrying or moving books, office furniture, equipment and supplies without assistance. They may exacerbate such injuries by the stretching, twisting and bending required by the office routine. Office workers are injured when struck by objects. File drawers may fall from the cabinet when pulled too far, type- writers can fall from a rolling table, or doors opened from the side opposite the worker may strike the employee. Similarly, injuries occur when workers strike objects. Employees bump into doors and desks. File cabinets inadvertently left open are a source of injury. Infectious cuts are caused by sharp objects normally found in office environments, such as staples and pens. Fingers can get caught under the knife edge of a paper cutter. 6.4. OFFICE HAZARD CONTROL The process for controlling hazards in the office is similar to that for controlling hazards in industrial settings. The preferred means of hazard control is to eliminate the hazard (engineering controls). Another means is minimizing exposure to the hazard (administrative controls). Office-related hazards are controlled by carefully considering the office environment and by following office safety procedures. 6.5. OFFICE ENVIRONMENT The layout of an office should incorporate the principles of work flow, taking into consideration safety and health, efficiency, and convenience. Recommended that handrails for stairs are required to be located 30 to 34 inches above the tread surface. Standards enforced under the Occupational Safety and Health Act of North Carolina (OSHANC) also address stairs. Generally speaking, enclosed stairways with four or more risers and less than 44 inches wide require a handrail on one side. Enclosed stairways wider than 44 inches require a handrail for both sides. Regardless of stair width, there must be a stair railing for each open side. An intermediate stair railing is required for stairs wider than 88 inches. Doors that open into a passageway can pose a hazard to oncoming traffic. Guardrails can be used to minimize that hazard or the floor can be painted to mark the swing area. Exits should be unobstructed and well illuminated. Emergency lighting is required for exit hallways or paths. Inadequate illumination caused by glare or shadows that interfere with vision can contribute to accidents. Illumination levels should be consistent to reduce visual fatigue created when one moves from bright surroundings into dark ones. The office layout should not require employees to face windows, unshielded lamps or other sources of glare
6.6. HAZARDS FROM ELECTRICAL EQUIPMENT • Using only proper equipment. • Arranging electrical extension cords to avoid tripping hazards. • Installing proper receptacles. Electrical appliances such as coffee makers, radios and lamps can become sources of fire or electrical shock. Appliances should be equipped with electrical plugs that have a ground prong, or the appliance should be marked “double insulated” by the manufacturer. Electrical extension cords must never be used as a substitute for permanent wiring. When extension cords are a temporary necessity, they should be taped down, clipped to the back of desks or covered with a rubber passageway if they cross the floor. All fuses and circuit breakers must be identified. This is easily accomplished by placing a label on each fuse or circuit breaker switch and a corresponding label on each receptacle and light switch. This practice will reduce the time needed to identify a specific fuse or circuit breaker when there is a need to turn it off. Floor surfaces should have a slip-resistant finish. Tripping hazards can be minimized by immediately replacing defective tiles and carpet or worn floor mats. Slip-resistant floor wax can give polished floors a higher coefficient of friction. Floor mats and runners offer a more slip-resistant protection for stairways or lobby entrances. Offices should have an area specifically designed for storing supplies. Materials should be neatly stacked in stable piles with the heaviest pieces on the bottom. Office equipment should not be placed on the edge of a table or desk. 6.7. OFFICE SAFETY PROCEDURES Following safe work procedures in the office can prevent many accidents. Running in offices must be prohibited. Those walking in a passageway should keep to the left. Accidents result when persons stand in front of doors, so employees should stand clear of the door swing path. Employees should not attempt to carry stacks of materials that are high enough to obstruct vision. If an elevator is available, it should be used instead of carrying stacks of material up flights of stairs. Proper attention should be given to the act of ascending or descending stairs. Stairways should not be areas for congregation. Those using the stairs should not crowd or push. Falls on stairs occur when people are distracted through conversation or by turning to another person while descending. Individuals should not stand near doors at stairways. Fall hazards can be prevented through good housekeeping in the office. Spilled liquids should be cleaned up promptly, and loose objects and broken glass should be removed when first noticed. Broken glass should be immediately vacuumed or swept and the fine pieces should be picked up with a damp cloth. Poor sitting habits can also lead to falls. Rolling in one’s chair across the floor, leaning sideways in a chair to pick up objects from the floor, and leaning back in the chair with feet on the desk are excellent examples of poor office safety procedures.
Filing cabinets can be a major cause of accidents and should be used with care. When using filing cabinets, follow these safety tips: • • • • • • •
Close all file drawers immediately after use. Close the file drawer with the drawer handle and not using feet. Open only one file drawer at a time to avoid toppling the cabinet. Never leave an open drawer unattended and never open a drawer if someone is underneath it. Never climb on open file drawers. Remove small stools (used to access upper file cabinet drawers) from passageways and safely store them. Wear finger guards to avoid paper cuts.
Other unsafe office procedures include storing pencils with points upward, placing scissors or knives with the point toward the user, using paper cutters without proper guards, and placing glass objects on a desk or table edge. Employees using lounges and eating areas should follow good housekeeping and safe operating procedures to prevent exposure to microwaves and burns from hot plates and coffee makers.

EMERGENCY Action Plan As a general recommendation, employers should develop an emergency action plan to address emergencies that the employer can expect in the workplace. Examples of such foreseeable emergencies are fire, toxic chemical releases, hurricanes, tornadoes, blizzards and floods. Some of the key components of an emergency action plan are the following: Emergency escape procedures and escape routes for employees to follow in the event of an emergency. These procedures should include floor plans that indicate the appropriate evacuation routes. • • •
How to account for all employees following evacuation. The rescue and medical duties for those employees, if any, who are to perform them. The preferred means of reporting fires and other emergencies.
Names or regular job titles of people responsible for the emergency action plan.
Employers are required to have both an emergency action plan and a fire prevention plan when portable fire extinguishers are provided, even though they are not intended for employee use. The elements of a fire prevention plan are: • • • •
Identification of the major workplace fire hazards and their proper handling and storage. Potential ignition sources (e.g., smoking) and their control procedures and the type of fire protection equipment or systems that can be used to control a fire. Names or regular job titles of personnel responsible for fire suppression equipment or systems. Names or regular job titles of personnel responsible for controlling fuel source hazards
