Question 1

OEM heat sink and fan assemblies are made by off brand manufacturers and are not to be trusted. T or F

Answer 1

False. OEM stands for Original equipment manufacturers and you will know absolutely that they will work.

Question 2

Third party heat sink and fan assemblies usually have one advantage. What is it?

Answer 2

They usually exceed the OEM heat sinks in amount of heat they dissipate.

Question 3

What is the advantage of liquid cooling a PC?

Answer 3

None. They are expensive, require extra hardware, and do about the same job as a heat sink and fan.

Question 4

What is fanless cooling? Is it an advantage or disadvantage for desktops? For laptops?

Answer 4

Fanless cooling describes a system with no special fan on the heat sink. If the desktop does not have adequate case fans, it could cause the CPU to overheat. For laptops, many do not have space for a heatsink-fan assembly and must count on the case fan to do the job. (is this correct?)

Question 5

How much thermal paste should be applied to the top of the CPU?

Answer 5

a small drop, spread very thinly and evenly on the case of the CPU

Question 6

Thermal paste can be applied thickly on the CPU case, it doesn’t matter. T or F

Answer 6

False. Too much can cause overheating and cause the CPU to be intermittent or fail.

Question 7

What program on modern systems does the computer use to set the motherboard speed, multiplier, and voltage?

Answer 7

CPUID

Question 8

In older systems, what methods were used to set motherboard speed, multiplier, and voltage?

Answer 8

moving a jumper, changing a CMOS setting, or using software

Question 9

How do you access the system setup utility?

Answer 9

while the computer is starting up, press any key. Some computers require the DELETE key to be pressed. If the Windows startup screen starts, you are too late.

Question 10

What are the disadvantages of overclocking?

Answer 10

it immediately voids any warrenties on the CPU, can make the CPU unstable and prone to lockups, reboots and shutdowns, and may fry the CPU

Question 11

Intel and AMD, although do not encourage overclocking, have programs to do so. What are they?

Answer 11

Intel - Intel Extreme Tuning Utility (Intel XTU)

AMD - AMD Overdrive Utility

Question 12

Several other adjustments need to be made if overclocking. What are they?

Answer 12

Using jumpers, CMOS or software, increase bus speed for the system.
Second, to provide stability, you need to slightly increase voltage going to the CPU

Question 13

What button on the motherboard can help return the system to working status if changes were made to the CMOS?

Answer 13

CMOS clear, or CLRTC

Question 14

What two issues cause the majority of CPU failures?

Answer 14

faulty installation and overheating.

Question 15

What three problems can show up as an installation CPU failure?

Answer 15

too much thermal paste, not enough thermal paste, or failure to connect the fan power to the motherboard

Question 16

Define an environmental failure that would cause a computer to act intermittently or shut down.

Answer 16

excess dirt in case or clogging fans, not enough ventilation to help fans cool internal components, running computer in a hot room

Question 17

What is BSoD? PSoD?

Answer 17

Blue screen of death (usually Windows), and Pinwheel of Death (usually Apple)

Question 18

What do registers provide for the CPU?

Answer 18

uses registers for temporary storage of interal commands and data

Question 19

What function does the external data bus have in the PC?

Answer 19

the external data bus provides a channel for the flow of data and commands between the CPU and RAM

Question 20

What is the function of the address bus in the PC?

Answer 20

The address bus enables the CPU to communicate with the memory controller chip.

Question 21

Which of the following terms are measures of CPU speed?
A.  megahertz and gigahertz
B. Megabyttes and gigabytes
C. Megahertz and gigabytes
D.  Frontside bus, backside bus

Answer 21

A.

Question 22

Which CPU feature enables the microprocessor to suppport running multiple operating systems at the same time?

Answer 22

virtualization support

Question 23

Into which socket could you place an Intel Core I5?
A. Socket LGA 1151
B. Socket AM3+

Answer 23

A.

Question 24

Which feature enables a single core CPU to function like two CPUs?

Answer 24

hyper-Threading
