This document provides an overview of random access memory (RAM), including its history, technologies, structure, types, capacity, manufacturers, and advantages/disadvantages. RAM is the most common type of computer memory, used to temporarily store programs and data for fast access by the processor. It is volatile, meaning information is lost when power is removed. RAM chips are organized into modules and allow any stored data to be accessed in any order.

4.  Random access memory (RAM) is the best known
form of computer memory.
 RAM is considered as volatile memory, which
means that the stored information is lost when
there is no power.
 RAM is made up of small memory chips that
form a memory module.
 Whenever you open a program, it gets loaded
from the hard drive into the RAM.
 This is because reading data from the RAM is
much faster than reading data from the hard drive

5. RAM (Random Access Memory) was invented by
Robert Heath Dennard.
At IBM Thomas J
Watson Research Center
in 1968
