
It also known as Main memory.

Usually volatile in nature.

Hold or store data and application temporarily.

Data is lost in case of power failure or power turn
off.

Faster than secondary memory

It is of two types :
a)ROM
b)RAM

4. RAM(Random Access
Memory)


Cheaper than RAMs.

It consists of:

PROM

EPROM

EEPROM

6. Secondary Memory
