What are difference between volatile and non volatile memory?

1. Volatile memory:
- Volatile memory requires power to retain data.
- Data is lost when power is turned off or lost.
- Examples of volatile memory include RAM (Random Access Memory) and cache memory.

2. Non-volatile memory:
- Non-volatile memory retains data even when power is turned off.
- Data is not lost when power is lost.
- Examples of non-volatile memory include ROM (Read-Only Memory), flash memory, and hard disk drives.

Overall, the main difference between volatile and non-volatile memory is the ability to retain data when power is turned off. Volatile memory loses data, while non-volatile memory retains data.
