#1. When working on a user’s PC you notice that the fan on the power supply is excessively dusty. After turning the PC off, what would you use to clean it?
Hardware / Preventive Maintenance

Spray bottle of Windex

A tooth brush

Compressed air

A damp paper towel

A vacuum cleaner

The best thing to use would be a can of “Compressed air.” You are least likely to cause damage when using it correctly. When using Compressed air, hold the can at least 6 inches from the target.

#2. Which IRQ is assigned for floppy drives?
Hardware / Installation, Configuration & Upgrading

IRQ 4

IRQ 6

IRQ 12

DMA 1

IRQ 8.5

IRQ 6 is reserved for the Floppy drive.
IRQ 4 is defaulted to COM1, COM3
IRQ 12 is empty and can be assigned any new device.

#3. What tool would be used to check for line voltage sags?
Hardware / Diagnosing & Troubleshooting

Surge protector

Feedback circuit

Terminal adapter

Polarity tester

High frequency monitor

A Polarity tester is useful whenever there is a need to check for the presence of low voltage in insulated conductors, without having to touch the live cable or wire.

#4. Which of the following storage components / media will give thefastest data access time?
Hardware / Motherboard, Processor & Memory

RAM

Serial Port

Zip Disk

Hard Disk

DVD

Data that is stored in RAM, which stands for Random AccessMemory, can be access quicker than any of the other choices.
RAM loses its contents when power is turned off.

#5. Of the following choices, which would be least likely to be infected by a computer virus?
Software (OS) / Diagnosing & Troubleshooting

A file located on a floppy disk

An e-mail from someone you know

A file stored in the C:/Windows directory

A Microsoft Word document

An application file on CD direct from the distributor

Unless the CD has a virus on it before it got to your computer, it is theleast likely to be infected. CDs that are packaged with applicationshave been finalized and become read-only.
