Question

Which memory devices are volatile and which are non volatile?

Answer 1

Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM, most types of magnetic computer storage devices (e.g. hard disk drives, solid state drives, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

Answer 2

Answer:

Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information;

it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost.

Most of the general-purpose random-access memory (RAM) is volatile.

ROM(Read Only Memory) is  non volatile.
