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
