Differentiate between volatile and non-volatile memory.

Differentiate between volatile and non-volatile memory.

Volatile memory refers to a type of computer memory that requires a constant power supply to retain stored data. It is temporary and loses its data when the power is turned off or interrupted. Examples of volatile memory include Random Access Memory (RAM) and cache memory.

On the other hand, non-volatile memory is a type of computer memory that retains stored data even when the power supply is turned off or interrupted. It is permanent and does not require continuous power to maintain data integrity. Examples of non-volatile memory include Read-Only Memory (ROM), hard disk drives (HDD), solid-state drives (SSD), and flash memory.

In summary, the main difference between volatile and non-volatile memory lies in their ability to retain data without a power supply. Volatile memory loses data when power is interrupted, while non-volatile memory retains data even when power is turned off.
