CompTIA Strata Chapter 2 Questions

Question 1

1. Which part of the processing component does the math?

A. CPU
B. Motherboard
C. RAM
D. Power Supply

Answer 1

A. CPU

The central processing unit (CPU) does the math.

Question 2

2. A typical modern CPU runs at which of the following speeds?

A. 1 Hz
B. 2 MHz
C. 2 GHz
D. 2 GB

Answer 2

C. 2 GHz

Most modern CPUs run at some speed measured in gigahertz (GHz).

Question 3

3. What’s of the following is not a processor type?

A. AMD
B. Cell
C. Intel
D. Windows

Answer 3

D. Windows

Windows is an operating system, not a processor type.

Question 4

4. Modern CPUs have one or more small, very fast pieces of RAM built-in. What’s that RAM called?

A. Cache
B. DIMM
C. SODIMM
D. System RAM

Answer 4

A. Cache

The cache is one or more small pieces of very fast RAM built into the CPU.

Question 5

5. Which of the following will most likely improve CPU performance? (select two)

A. Lower speed
B. Going from single core to multicore
C. Adding more cache
D. Lowering gigabytes

Answer 5

B. Going from single core to multicore
C. Adding more cache

Among other improvements, CPU makers have gone from single core to multicore and added more cache to modern CPUs. These improvement lead to better performance.

Question 6

6. Which feature didi desktop CPU makers borrow from portable versions of processors to make newer CPUs better?

A. Multiple cores
B. Extra cache
C. Lower power consumption
D. Bigger sockets

Answer 6

C. Lower power consumption

Portable CPU engineers have long pushed for lower-power CPUs. Desktop engineers picked up that option and found that lower power meant also less heat. They could push the CPU even more and thus get better performance.

Question 7

7. What type of RAM would you most likely find in a portable computer?

A. DIMM
B. PIMM
C. SIMM
D. SODIMM

Answer 7

D. SODIMM

Most portable computers use SODIMM RAM sticks.

Question 8

8. Which of the following RAM sticks would work with a DDR2-533 MHz motherboard?

A. DDR2-266
B. DDR2-400
C. DDR2-533
D. DDR3-533

Answer 8

D. DDR3-533

Of the four choices, only the DDR2-533 would work. The other two DDR2 sticks are too slow. The DDR3 stick won’t fit in a DDR2 motherboard.

Question 9

9. What’s the basic rule on RAM?

A. Make the RAM sticks match.
B. Use only DDR2 or better RAM.
C. Use only DDR3 or better RAM.
D. Use only SODIMMs if possible.

Answer 9

A. Make the RAM sticks match.

The basic rule with RAM is to use identical RAM sticks.

Question 10

10. When shopping for a computer case, what must you consider?

A. The case needs to be able to handle the speed of the processor
B. The case should be black or at least black and silver.
C. The case should be compatible with the motherboard from factor.
D. It doesn’t matter. Pick the case that looks the best.

Answer 10

C. The case should be compatible with the motherboard from factor.

Acomputer case and a motherboard must be the same form factor. Otherwise, the motherboard won’t fit.
