Types of Memory on the basis of Retention Power
- Volatile Memory
- Non-Volatile Memory
Definition of Volatile Memory
Volatile memory requires power to retain data and is primarily used for temporary storage. it retains the data / information as long as power supply is on, but when power supply is off or interrupted the stored data / information is lost.
Example
Examples of such memory are RAM (Random Access Memory), Cache memory and Registers.

Example
Examples of such memory include ROM (Read Only Memory), which stores essential boot-up instructions, Flash memory used in USB drives, and HDDs for storing programs, videos, documents.
