Quarter I

4 hrs.

Grade Level Standard This is a specialization course which leads to Computer Hardware Servicing National Certificate Level II (NC II). It covers two (2) core competencies that a Grade 10 Technology and Livelihood Education (TLE) student ought to possess, namely: 1) communicate effectively using the English language and 2) deliver quality customer service. The preliminaries of this specialization course include the following: 1) discussion on the relevance of the course, 2) explanation of key concepts relative to the course, and 3) exploration on career opportunities. Content Standard The learner demonstrates understanding of environment and market in Computer Hardware Servicing in one’s province. Performance Standard The learner independently creates a business vicinity map reflective of potential market in Computer Hardware Servicing in a province. Learning Competencies  Develop a quality and marketable product or service in Computer Hardware Servicing  Select a business idea based on the criteria and techniques set  Develop a brand for the product V. Introduction People who aspire to start a business need to explore the economic, 6

cultural, and social conditions prevailing in an area. Needs and wants of the people in a certain area that are not met may be considered as business opportunities. Identifying the needs of the community, its resources, available raw materials, skills, and appropriate technology can help a new entrepreneur in seizing a business opportunity. To be successful in any kind of business venture, potential entrepreneurs should always look closely at the environment and market. They should always be watchful on the existing opportunities and constraints. The opportunities in the business environment are those factors that provide possibilities for a business to expand and make more profits. Constraints, on the other hand, are those factors that limit the business to grow, hence reduce the chance of generating profit. One of the best ways to evaluate the opportunities and constraints is to conduct Strengths, Weakness, Opportunities and Threats (SWOT) Analysis. VI. Objectives With your assistance and guidance in facilitating this module, learners are expected to understand the underlying principles and concepts of environment and market more particularly in: -

identifying what is of “value” to the customer, identifying the customer to sell to, explaining what makes a product unique and competitive, applying creativity and innovative techniques to develop marketable product, and - employing a unique selling proposition (USP) to the product and or service.

What to TRANSFER 2.2- Networking Devices, Media and Connector  Guide the learners in creating their own Ethernet cable by stating the general directions, materials and tools needed and by discussing the procedures for the said activity.  Inform the learners about the rubrics to be used in order to rate their performance (rubrics is on page 90). Task: Create your own Ethernet Cable Directions: Prepare the following tools and materials in fabricating your own cross over and straight- through cables. Materials: 1) 6 meters Ethernet Cable Category 5e or Cat5e- standard wire for cabling; 2) RJ45 crimpable connectors for Cat5e; Tools: 3) RJ45 Crimping tool; 4) Wire cutter, stripper or pliers; and 5) Ethernet cable Tester / LAN Tester Take Note: Be careful when using the tools. You just need to follow the procedures cited in this module and apply the safety precautions to avoid injury or any unwanted incident. You will be given 30 minutes to complete the task. You will be rated according to the performance rubric. Procedures: 1. Cut into the plastic sheath 1 inch from the end of the cut cable. The crimping tool has a razor blade that will do the trick with practice. 2. Unwind and pair the similar colors. 3. Pinch the wires between your fingers and straighten them out as shown. The color order is important to get correct. 4. Use scissors to make a straight cut across the wires 1/2 Inch from the cut sleeve to the end of the wires. 5. Push the wires into the connector. Note the position of the blue plastic shielding. Also note how the wires go all the way to the end.

41

6. A view from the top. All the wires are all the way in. There are no short wires. 7. Crimping The Cable – carefully place the connector into the Ethernet

Crimper and cinch down on the handles tightly. The copper splicing tabs on the connector will pierce into each of the eight wires. There is also a locking tab that holds the blue plastic sleeve in place for a tight compression fit. When you remove the cable from the crimper, that end is ready to use. 8. For a standard "Straight Through" cable, repeat all steps and wire color order on the other end of cable. For a cross-over cable, the other end will have a different color order as shown by the crossover picture above. 9. Make sure to test the cables before installing them. An inexpensive Ethernet cable tester does this quite well.
