Which of the following are valid types of memory modules used in a computer? (Choose Three)
ZIMM
SwapSIM
RIMM
DIMM
ZDRIMM
SIMM
Correct Answers = C, D, and F.
RIMM, DIMM, and SIMM are valid memory modules. All others listed are not.
Of the following types of RAM, which is the fastest?
Page fault RAM
FPM DRAM
EDO RAM
Swap file RAM
Correct Answer = C.
EDO is faster than FPM memory. Page fault RAM and swap file RAM are made-up names intended to trick you.
Which type of memory is internal to the processor?
Level 1 cache
Bus RAM
BEDO RAM
EDO RAM
Parity with ECC
Correct Answer = A.
Level 1 cache is considered primary cache and is internal or built into the processor itself.
Which type of memory uses burst mode to send data?
CD-RW RAM
SDRAM
High-speed RAM
Coast RAM
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.

168-pin DIMM
72-pin SIMM
RIMM
30-pin SIMM
Correct Answer = B.
What type of memory module is displayed below?

30-pin SIMM
72-pin SIMM
SGRAM
168-pin DIMM
Correct Answer = D.
How many DIMMs are required per memory bank on a motherboard?
Two
One
1,073,741,824
Eight
Correct Answer = B.
DIMMs can be installed in units of one (one module) per memory bank. In other words, you can install one DIMM on a motherboard if you so choose.
Which of the following statements is not true?
A kilobyte is equal to 1024 bytes.
A megabyte is equal to 1,048,576 bytes.
A gigabyte is equal to 1,073,741,824 bytes.
All of the above statements are true.
Correct Answer = D.
All of the statements are in fact true. Please refer to Table 4.1, RAM Units and Size.
Which of the following memory modules are specifically designed for laptop computers?
FSO RAM
SOSORIMM
SODIMM
SDIMM
None of the above
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 on a module with 144 pins at a transfer rate of 64 bits.
What would a technician use WRAM for?
Video
Audio
Windows memory
L3 cache acceleration
None of the above
Correct Answer = A.
WRAM is used for video.

Correct Answer = D.
Which type of memory uses 184 pins and has a memory bus width of 16 bits (or 2 bytes wide)?
SIMM
DIMM
RIMM
SODIMM
NOSDRMM
None of the above
Correct Answer = C.
A RIMM module has 184 pins and has a memory bus width of 16 bits (or 2 bytes wide). Please refer to Table 4.3, Memory Module Quick Reference.
