What does volatile memory mean?

What does volatile memory mean?

• A. Data is lost when power is turned off.
• B. Data is saved permanently.
• C. Data cannot be accessed quickly.
• D. It is stored on magnetic media.

Answer: (A)

Volatile memory refers to memory that needs power to keep the information stored. When the computer is turned off, anything held in this memory is lost. It’s the type used for active data and running programs because it’s fast, but it doesn’t preserve data without power. Saving work to non-volatile storage like a hard drive or SSD keeps it even when power is gone. The other statements describe data persistence, access speed, or the physical medium, which are not what volatility means.
