Which of the following is a volatile memory?

Correct option is C

The correct answer is (C) RAM.

• RAM (Random Access Memory) is a type of volatile memory, which means it loses its stored data when the power is turned off.

• It is used by the CPU to store data and instructions that are actively used during the computer's operation.

Information Booster:
• Volatile memory requires constant power to retain data.
• RAM is used for temporary storage of data, such as the operating system, application programs, and data currently in use.
• There are two main types of RAM: DRAM (Dynamic RAM) and SRAM (Static RAM).
• The speed and efficiency of RAM directly affect the performance of a computer.
• Other volatile memory examples include cache memory and registers in a CPU.

Additional Information:

• (A) ROM: ROM (Read-Only Memory) is non-volatile memory, meaning it retains its data even after power is turned off.

• (B) Hard Disk: Hard Disk is a non-volatile storage device used for permanent data storage.

• (D) Pen Drive: A Pen Drive is a non-volatile flash memory storage device that retains data even without power.
