Which of the following are types of Random Access Memory (RAM) ?
Each correct answer represents a complete solution. Choose all that apply.

A.
EDO RAM

B.
DRAM

C.
SRAM

D.
VRAM

E.
NRAM

Explanation:

These are the type of Random Access Memory:
DRAM
EDO RAM
SRAM
VRAM
What is the function of DRAM? Hide

Dynamic Random Access Memory (DRAM) is used as the primary memory for computers and
workstations. It requires having
its storage cells refreshed or given a new electronic charge every few milliseconds.
What is an EDO RAM? Hide
EDO RAM stands for Extended Data Out RAM. It is a type of memory, which improves performance
of the computer by
eliminating memory wait states.
What is the function of SRAM? Hide
Static Random Access Memory (SRAM) is used for a computer’s cache memory and as part of the
random access memory
digital-to-analog converter on a video card. Unlike DRAM, SRAM does not have to be periodically
refreshed. SRAM retains
data bits in its memory as long as power is being supplied. SRAM is significantly faster and more
expensive than DRAM.
What is VRAM? Hide
VRAM, also known as Video RAM, is used to store image data for processing by the video adapter. It
is the memory that stores information about the pictures that display on the monitor screen.
Answer option E is incorrect. There is no RAM such as NRAM.
