Antistatic pad/wrist strap An antistatic pad provides an insulated covering to prevent static electricity from moving between objects and damaging computer components. When working with computer components, use a wrist strap connected to the antistatic pad, and connect the pad to a ground. Extension magnet An extension magnet is a small magnet on a collapsible rod. Use the extension magnet to retrieve screws that have fallen into a computer case or other areas you cannot reach. As an alternative to a magnet, use an extension tool with retractable prongs. 3-pronged parts retriever A 3-pronged parts retriever is used to grasp and retrieve small parts that have fallen into difficult to reach areas. Multimeter A multimeter is a device for testing various electrical properties. For example, most multimeters can measure: AC and DC voltage Current (amps) Resistance (ohms) Capacitance Frequency Power supply tester A power supply tester is a custom multimeter that is used for testing output from a PC power supply. The power supply tester has multiple connectors to test the output for each connector type. Cable tester A cable tester verifies that a network can carry a signal from one end to the other, and that all wires within the connector are in their correct positions. Most testers have a single unit that tests both ends of the cable at once. Many testers come with a second unit that you can plug into one end of a long cable run to test the entire cable. Loopback plug A loopback plug is used to test network communications by redirecting a signal from the transmit port on a device to the receive port on the same device. Use the loopback plug to verify that a device can both send and receive signals. Known good spares Known good spares are a set of components that you know are in proper functioning order. If you suspect a problem in a component, swap it with the known good component. If the problem is not resolved, troubleshoot other components. Examples of using this strategy are: Changing the cable connecting a computer to the network Connecting a different monitor to a computer Replacing an expansion card POST card A POST card is an expansion board that you insert into an expansion slot. It is typically used to troubleshoot a computer system that doesn't start up correctly. The POST card displays output from the BIOS during the Power-On Self-Test (POST).

PC Maintenance 0:00-0:10 In this lesson, we'll discuss PC maintenance. Maintaining your computer equipment will help extend the life of the components. Proper Environment 0:11-0:41 The first thing you need to look at is creating the proper environment for your computer hardware.This will help your hardware last longer. Some considerations include keeping the temperature between 70 and 74 degrees, and keeping the humidity levels between 40 and 70%. Make sure the computer rooms have separate and redundant cooling systems, and use a positive pressure systemin your computer rooms and wire ways to ensure a supply of good, clean filtered air. Frequently cleaned systems which operate in a dirty, dusty, or smoky environment.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
