Answers

1.

Correct Answers = A and C

The AMD Athlon and the AMD K6 are valid AMD processors. Intel developed the Celeron processor. K9 is used as a description for police dogs.

2.

Correct Answer = C

The Intel Pentium II 300 runs at 66MHz motherboard speed. See Table 16.1 for a Pentium II processor and motherboard speed comparison.

3.

Correct Answer = A

The Pentium II 350MHz through the Pentium III series processors are intended to run at 100MHz motherboard bus speed.

4.

Correct Answers = B and D

If your processor fan has failed or malfunctioned, your system may lock up or “halt” and your processor may suffer irreversible damage due to overheating.

5.

Correct Answer = B

The AMD Duron processor was developed for midrange workstations.

6.

Correct Answer = D

An antistatic ESD bag will protect your processor as well as other electronic computer components from electrostatic discharge.

7.

Correct Answer = D

If you are considering upgrading your processor, it is a must that you consult both the processor and motherboard manufacturer’s instructions regarding the specific voltage requirements for your new processor’s core and I/O functions. You may need to add a VRM depending upon the voltage requirement of your new processor.

8.

Correct Answer = D

The L3 cache addition to newer processors has dramatically increased the speed at which a processor, or dual processors, can access stored information. This, in turn, provides better processor support for overall application access speed and system support.

9.

Correct Answers = A and B

Both Pentium 4 and Celeron’s latest incarnation use socket 478. The Duron uses both Socket A and Slot A technology, and the Pentium 3 uses either Slot 1 or Socket 370 technology.

10.

Correct Answer = B

The first Pentium 4s were enabled with 256K of L2 cache, which has since been updated to 512K.

11.

Correct Answers = A and C

A liquid cooling system requires a radiator (with fan to help dissipate heat from the radiator), tubing, water reservoir, and a water block (which acts as a sort of heat sink for the processor, that water flows through a radiator/fan and a water block). The water block as the primary cooling device replaces a heat sink/fan combination for the CPU in a liquid cooling setup. While a water filter sounds good in theory, the water/coolant must be changed out routinely to avoid algae/mineral deposits.
