Which of the Following Memory is Volatile?

Examples of Volatile and Non-Volatile

ROM: ROM is a Non-Volatile Memory. Read-only memory is referred to as ROM. When the computer is switched down, the data in ROM is preserved.

PROM: Programmable read-only memory is known as a PROM. 

EPROM: Erasable Programmable Read-Only Memory is known as EPROM.

About RAM

A type of computer memory called random-access memory, which can be read and updated in any sequence, is often used to store operational data and programme code. Like the time needed to read and write items of data which differs significantly based on their physical locations on the recording medium due to mechanical constraints, a random-access memory device allows data items to be read or written in almost the same amount of time regardless of the physical location of data inside the memory, hard discs, DVD-RWs, CD-RWs, the older drum memory and magnetic tapes.

Summary:

Which of the following memory is volatile? (A) RAM (B) ROM (C) PROM (D) EPROM

RAM is a volatile memory. A computer's volatile memory loses all of its data when turned off. RAM is a primary memory that can be only accessible from the CPU of that system.
