RAM: stands for Random Access Memory and is a read write
memory of the computer. In a RAM, any location can be
accessed in a random manner and the access time is the same
for each location.
A chip actually contains lot of memory cells within it. Each
cell contains group of bits that are accessed together.The
Size of memory data register is equal to the number of bits
stored in each of the cell. There are two important types of
RAM-Static RAM and dynamic RAM.
ROM: ROM stands for Read Only Memory, i.e. nothing can be
written on it. ROM is a non-volatile memory, i.e. the
information stored on it is not lost when power goes off. It
is used for storing the bulk of programs that are permanent
residents of computer.
