Answers

1.

Correct Answers = C, D, and F

RIMM, DIMM, and SIMM are valid memory modules. All others listed are not.

2.

Correct Answer = C

EDO is faster than FPM memory. Page Fault RAM and Swap File RAM are made-up names intended to trick you.

3.

Correct Answer = A

Level 1 cache is considered primary cache and is internal or built into the processor itself.

4.

Correct Answer = B

SDRAM uses burst mode (automatic retrieval of data before it is requested) for read and write operations. SDRAM sends data in high-speed bursts by utilizing burst mode.

5.

Correct Answer = D

6.

Correct Answer = B

7.

Correct Answer = D

8.

Correct Answer = B

DIMMS can be installed in units of 1 (one module) per memory bank. In other words, you can install one DIMM on a motherboard if you so choose.

9.

Correct Answer = D

The correct answer to this question is D. All statements are, in fact, true. Please reference Table 17.1, RAM Units and Size.

10.

Correct Answer = C

A SODIMM is a smaller DIMM specifically designed for laptop computers. There are two major types of SODIMMs. They come on a module that is 72 pins with a transfer rate of 32 bits, or a module with 144 pins at a transfer rate of 64 bits.

11.

Correct Answer = A

WRAM is used for video.

12.

Correct Answer = B

13.

Correct Answer = C

14.

Correct Answer = D
