Unit 4 Review questions


1.   Which is not a component of a CPU?

A – Bus architecture

2.   The math coprocessor was the predecessor to which CPU component?


3.   A single-core processor has one of what component?

B Execution unit

4.    ______________ are very small, very fast, memory locations for holding

instructions or units of data.


5.   Which type of bus connects the processor to the main memory?

A Address bus

6.    Which processor caching level is the fastest for accessing data?

A Level 1

7.    Which of the following performance features can overheat the processor?

B Overclocking

8.    True or false? Most current processors have both L1 and L2 caches.


9.   The data bus for current CPUs is how many bits?

C 64

10.                  The _____________ chip controls interactions between the CPU, memory, PCIe

and AGP video control circuitry.


11.                  The plain chip called a “die” is built into a(n) _____________ so that it can connect to the rest of the circuitry in your computer.


12.                  Which package type is similar to the PGA-style packages, except that the die is exposed on top, enhancing heat transfer and cooling options?


13.                  Which package type has no pins, but uses small raised contacts instead?


14.                 Which socket type is similar to the Socket 7 design, but with six staggered rows of

pins instead of five?

A Slot A

15. True or false? CPUs of the same class are interchangeable. For example, you can replace any Pentium 4 CPU on a motherboard with any other Pentium 4–class CPU.

False. You must match the physical, electronic, and performance characteristics of a CPU to the motherboard.

16.                 A(n) ________ card is a circuit board that connects to a motherboard to provide additional expansion slots or sockets.


17.                  True or false? Thermal compound is basically a grease-like fluid used between the CPU and its heat sink or cooling fins.

True. The compound improves heat flow by closely mating the CPU die to the heat sink or fan.

18.                  Which cooling system relies on small tubes filled with a small amount of fluid?

B Heat pipes

19.                  Which cooling system uses an electronic component that gets colder when voltage is applied?

D Peltier coolers

20.                 You open your PC and look at the CPU. How can you tell if it uses active or passive cooling?

If there is just a heat sink on the CPU, it uses passive cooling. If there’s a fan attached to the CPU, it uses active cooling.

21.                  Before the Pentium CPU was introduced, what was the most common CPU cooling mechanism?

A simple fan, typically part of the power supply, was all that was used with the 80286 and 80386 CPUs. Some 80386 and most 80486 CPUs also used cooling fins.


Unit 5 Review questions

The battery shown in the following graphic is used to provide power to what component?



C Firmware

D RAM                                           

  1. True or false? The same key combination will get you access to the system utility on all personal computers, except laptops.
  2. Which is not a reason to update your system BIOS?

A Your system has device problems or other bugs that your PC manufacturer identifies as being caused by BIOS problems.

B Your system has device problems that you can attribute to no other cause than the BIOS.

D You need to use new hardware options that, while supported by your motherboard, aren’t supported by your BIOS.

4.   True or false? Every BIOS manufacturer uses the same flashing utility.

5.   What is the best source for BIOS updates?

6.   Which of the following is not a step in the POST process?

A BIOS identification

B Core hardware test

C Main system memory test

D Master boot record being read from the boot drive

E Video subsystem test

7.   True or false? The boot processes for a cold boot and a warm boot are exactly the same.

8.   True or false? To boot the computer, your boot device must bean internal hard disk, internal optical drive, internal floppy drive, or USB flash drive.

9.   Why does your computer use beep codes to indicate an error, rather than simply displaying a message on the monitor?
