Question:
Which of the following is a volatile memory?
Which of the following is a volatile memory?
Show Hint
A simple way to remember is that volatile means it vanishes. The data in RAM vanishes when the power is gone. Data on your hard drive or flash drive stays put.

The Correct Option is A
Solution and Explanation
Memory is classified as volatile or non-volatile.
Volatile memory requires power to maintain the stored information. If the power is turned off, all data stored in it is lost.
Non-volatile memory retains the stored information even when not powered.
Let's analyze the options:
(A) RAM (Random Access Memory): This is the main working memory of a computer. It is volatile. When you turn off your computer, the contents of RAM are erased.
(B) ROM (Read-Only Memory): This memory is used to store firmware and bootup instructions. It is non-volatile.
(C) Hard Disk: This is a magnetic storage device used for long-term storage. It is non-volatile.
(D) Flash Drive: This is a solid-state storage device. It is non-volatile.
Therefore, RAM is the volatile memory among the given options.
