It is temporary storage.
It is used in normal operations.

It always retains its data.
It is used in calculators and peripheral devices.
It stores crucial information that is required to operate the system.
There are four types of ROM: MROM, PROM, EPROM, and EEPROM.
The two kinds of Main Memory are
Primary Memory and Secondary Memory are the two types of main memory. The memory unit can be implemented using a variety of memory chips- different speeds, different manufacturing technology, and different sizes.
