Tools in Maintaining Computer and Network Systems.pptx
- 1. Tools in Maintaining Computer and Network Systems (HARDWARE)
- 2. • This chapter discusses safe lab procedures and basic safety practices for the workplace, correct tool usage, and the proper disposal of computer components and supplies. The guidelines presented help keep IT workers safe while protecting the environment and workplace from contamination caused by improperly discarded materials.
- 3. Proper Use of Tools (2.2) • Using tools properly helps prevent accidents and damage to equipment and people. This section describes and covers the proper use of a variety of hardware, software, and organizational tools specific to working with computers and peripherals.
- 5. Hardware Tools • For every job there is the right tool. Make sure that you are familiar with the correct use of each tool and that the correct tool is used for the current task. Skilled use of tools and software makes the job less difficult and ensures that tasks are performed properly and safely. • A toolkit should contain all the tools necessary to complete hardware repairs. As you gain experience, you learn which tools to have available for different types of jobs. Hardware tools are grouped into four categories: – ESD tools – Hand tools – Cleaning tools – Diagnostic tools
- 6. This shows some common tools used in computer repair.
- 7. ESD Tools (2.2.1.2) • There are two ESD tools: the antistatic wrist strap and the antistatic mat.
- 8. Antistatic Wrist Strap • The antistatic wrist strap protects computer equipment when grounded to a computer chassis.
- 9. Antistatic Mat • The antistatic mat protects computer equipment by preventing static electricity from accumulating on the hardware or on the technician.
- 10. Hand Tools (2.2.1.3) • Most tools used in the computer assembly process are small hand tools. They are available individually or as part of a computer repair toolkit. Toolkits range widely in size, quality, and price. Some common hand tools and their uses are:
- 11. Hand Tools • Flat-head screwdriver: Used to tighten or loosen slotted screws.
- 12. Hand Tools • Phillips-head screwdriver: Used to tighten or loosen cross-headed screws.
- 13. Hand Tools • Torx screwdriver: • Used to tighten or loosen screws that have a star-like depression on the top, a feature that is mainly found on laptops.
- 14. Hand Tools • Hex driver: Used to tighten or loosen nuts in the same way that a screwdriver tightens or loosens screws (sometimes called a nut driver).
- 15. Hand Tools • Needle-nose pliers: Used to hold small parts.
- 16. Hand Tools • Wire cutters: Used to strip and cut wires.
- 17. Hand Tools • Tweezers: Used to manipulate small parts.
- 18. Hand Tools • Part retriever: Used to retrieve parts from locations that are too small for your hand to fit.
- 20. Hand Tools • Flashlight: Used to light up areas that you cannot see well.
- 21. Hand Tools • Wire stripper: A wire stripper is used to remove the insulation from wire so that it can be twisted to other wires or crimped to connectors to make a cable.
- 23. Hand Tools • Crimper: Used to attach connectors to wires.
- 25. Hand Tools • Punch-down tool: Used to terminate wire into termination blocks. Some cable connectors must be connected to cables using a punch down tool.
- 26. Cleaning Tools (2.2.1.4) Having the appropriate cleaning tools is essential when maintaining and repairing computers. Using the appropriate cleaning tools helps ensure that computer components are not damaged during cleaning. Cleaning tools include the following:
- 27. Cleaning Tools • Soft cloth: Used to clean different computer components without scratching or leaving debris
- 28. Cleaning Tools • Compressed air: Used to blow away dust and debris from different computer parts without touching the components
- 30. Cleaning Tools • Cable ties: Used to bundle cables neatly inside and outside of a computer
- 31. Cleaning Tools • Parts organizer: Used to hold screws, jumpers, fasteners, and other small parts and prevents them from getting mixed together
- 32. Diagnostic Tools • Diagnostic tools are used to test and diagnose equipment. Diagnostic tools include the following: • A digital multimeter, is a device that can take many types of measurements. It tests the integrity of circuits and the quality of electricity in computer components. A digital multimeter displays the information on an LCD or LED.
- 34. Diagnostic Tools • A loopback adapter, also called a loopback plug, tests the basic functionality of computer ports. The adapter is specific to the port that you want to test.
- 35. • The toner probe, is a two-part tool. The toner part is connected to a cable at one end using specific adapters, such as an RJ-45, coaxial, or metal clips. The toner generates a tone that travels the length of the cable. The probe part traces the cable. When the probe is in near proximity to the cable to which the toner is attached, the tone can be heard through a speaker in the probe.
