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
