A standard multimeter is ideal for measuring a monitors high voltage output.
Answer: B
Correct answer: False
A CRT anode carries tens of kilovolts, hundreds of times beyond a standard meter's range and its insulation. Measuring it requires a high-voltage probe designed for the purpose.

From what location are the 1st computer instructions available on boot up?
Answer: A
Correct answer: ROM BIOS

Which device should not be plugged into a standard ups?
Answer: B
Correct answer: laser printer

What is the recommended way to fix the registry description for the printer driver
Answer: D
Correct answer: Remove the printer driver and re-install it
Removing the driver through the operating system's own interface clears its registry entries in the proper order and the reinstallation writes them afresh. Editing the registry by hand risks leaving inconsistent entries behind.

After you service a laser printer, you notice dirty print. Which of the following would correct the problem.
Answer: C
Correct answer: Run several blank pages

Modems use transmission.
Answer: B
Correct answer: asynchronous
A modem sends each character framed by start and stop bits, with no clock shared between the two ends - that is asynchronous transmission. Synchronous transmission requires a common clock.

Which common bus specification provides the fastest data transfer rate?
Answer: C
Correct answer: PCI
PCI runs at 33 MHz and 32 bits, giving about 133 MB/s, against the VL bus's dependence on the processor bus and ISA's 8 MHz. It is also processor-independent, which is why it outlasted VL.
