|
|
|
You are trying to add a computer to a wireless network but cannot detect the access point. What would you suspect the problem to be?
|
The computer's wireless adapter is not supported by the AP or the computer is not in range or there is some sort of interference.
|
|
|
A single PC on a network cannot connect to the Internet. Where would you start troubleshooting?
|
Test the PC's TCP/IP configuration, specifically the default gateway or name resolution.
|
|
|
Your company is moving to new premises. The building is already flood-wired with network cabling. What tool would you use to test whether the cabling supports Gigabit Ethernet?

|
|
|
Why must all electrical equipment be protected by a fuse?
|
A fuse prevents too much current flowing through the circuit. Excessive current can cause wiring to overheat, creating a fire hazard.
|
|
|
If static electricity is not harmful to humans, why is it damaging to electronic components?
|
These components are designed to work at very low voltages; a static discharge is very high voltage. No damage occurs to humans because the current is very small but the tiny wires and components of electronic circuits are much more fragile.
|
|
|
You have to service a PC but anti-static protection is not available. You know that you can ground yourself by touching the metal chassis of the PC, but should you do this before or after unplugging the PC from mains power?
|
For safety reasons, always unplug the PC from mains power before opening the case.
|
|
|
Why is it better to use approved cleaning products for computer hardware?
|
Household cleaners tend to leave deposits, dust, or fiber traces that can interfere with the operation of computer components. Some components (such as display screens) use delicate materials that can be damaged by chemicals in non-approved products.
|
|
|
What precaution should you take when using spray cleaners?
|
Always spray the cloth rather than the equipment, especially if cleaning around ventilation slots.
|
|
|
Why should you never use a home vacuum cleaner to clean a PC?
|
Because they generate large amounts of static electricity that may damage sensitive components.
|
|
|
What are the principal environmental hazards to consider when installing PC equipment?
|
Heat and direct sunlight, excessive dust and liquids, and very low or high humidity. Equipment should also be installed so as not to pose a topple or trip hazard.
|
|
|
True or false? Rocking a card from side-to-side is the best way to release it.
|
False.
|
|
|
How is the heatsink attached and what problems can occur releasing it?
|
The heatsink is attached to a clip on the motherboard. There will also be a power connector for the fan assembly. The clip is often quite tight and difficult to release. Another issue can arise where too much thermal paste has been applied, causing the heat sink to stick to the processor.
|
|
|
What must you check when inserting a PGA CPU chip?
|
That pin 1 is aligned properly and that the pins on the package are aligned with the holes in the socket. Otherwise, you risk damaging the pins when the ZIF lever is lowered.
|
|
|
What practical issues can make the installation of PATA drives difficult?
|
Parallel data cables are quite short but fairly bulky. If the case layout is not good, adding a 3.5" hard drive on the same cable as a 5" CD-ROM drive can be tricky.
|
|
|
What setting should you check before installing a PSU?
|
That the voltage selector is set to the correct voltage (or if there is no selector that the PSU is suitable for the voltage used by the mains supply).
|
|
|
What is the process for installing memory in a notebook?
|
Locate the memory slot, which is usually accessed via a panel on the back cover. Move the connector up to 45º and insert the memory card, taking care to align it correctly. Push the card flat again.
|
|
|
