Option 3 : Public memory

The correct answer is option 3, i.e. Public memory.

Computer memory is a physical device that is able to store data and information.

It can store permanently or temporarily.
It is semiconductor memory made up of integrated circuits.
Primary memory is the main memory of the system which is directly accessed by the processing units.
- Examples: RAM, ROM, EPROM, Cache memory etc.
Secondary memory is the external storage device.
- Examples: Hard Disk, Floppy Disk, Magnetic Tapes etc.
Tertiary Memory consists of high capacity data to add vast numbers of removable media like tapes and optical discs.
- Examples: Tape Library and Optical Jukebox.
