Red Hat Linux Red Hat Linux was a popular Linux based operating system until its discontinuation in 2004. Red Hat Linux introduced a graphical installer called Anaconda, intended to be easy to use for novices, and which has since been adopted by some other Linux distributions. It also introduced a built-in tool called Lokkit for configuring the firewall capabilities. It was the first Linux distribution to use the RPM Package Manager as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.

Linux is an operating system -- very much like UNIX -- that has become very popular over the last several years. Operating systems are computer programs. The kernel's primary function is to manage the computer's hardware and resources and allow other programs to run and use these resources

Linux

What is it?

Cost

linux is an example of Open Source software development and Free Operating System (OS).

Linux can be freely distributed, downloaded freely, distributed through magazines, Books etc. There are priced versions for Linux also, but they are normally cheaper than Windows.

Windows

Windows is the family of operating system (OS) from Microsoft, which is the most famous OS in the world.

For desktop or home use, Windows can be expensive. A single copy can cost around $50 to $ 450 depending on the version of Windows.

Usage

Development and Distribution

Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers and video game consoles, to mainframes and supercomputers.

On PC's desktops, laptops, servers and some phones.

Linux is developed by Open Source development i.e. through sharing and collaboration of code and features through forums etc and it is distributed by various vendors.

Windows is developed and distributed by Microsoft.

GUI

Text mode interface

Linux typically provides two GUIs, KDE and Gnome. But there are millions of alternatives such as LXDE, Xfce, Unity, Mate, twm, ect.

The Windows GUI is an integral component of the OS and is not replaceable. This can be a when it comes to Windows 8's Metro.

BASH (Bourne Again SHell) is the Linux default shell. It can support multiple command interpreters.

Windows uses a command shell and each version of Windows has a single command interpreter with dos-like commands, recently there is the addition of the optional PowerShell that uses more Unix-like commands.

Security

Threat detection and solution

Linux has had about 60-100 viruses listed till date. None of them actively spreading nowadays.

“Analysis of the Impact of Open Source Software” there have been more than 60,000 viruses in Windows. Anti Virus cost about $20 to $400

In case of Linux, threat detection and solution is very fast, as Linux is mainly community driven and whenever any Linux user posts any kind of threat, several developers start working on it from different parts of the world

After detecting a major threat in Windows OS, Microsoft generally releases a patch that can fix the problem and it can take more than 2/3 months. Sometimes sooner, Microsoft releases patches and updates weekly.
