Answer 2

Primary Memory Unit holds data temporarily.

• It is the main memory of computer system.

• It has limited storage and because of this it is very expensive.

• It loses the data or information stored in it as when the computer system switches off or resets and that's why primary memory is volatile.

• It is often referred as temporary memory.

• It is made up of semiconductor devices.

• In this memory, the stored pieces of data is directly accessed by CPU at a very fast speed.

• The primary memory has two parts -

                 (1) Random Access Memory (RAM) and,

                (2) Read Only Memory (ROM)
