Volatile memory loses data when power is off, while non-volatile memory retains data without power.
Volatile Memory vs. Non Volatile Memory

Key Differences

Volatile Memory, like RAM, needs constant power to maintain stored information, making it fast but temporary. Non-Volatile Memory, such as SSDs, preserves data even when the power is off, offering permanent storage.
