Which memory is typically volatile and loses data when power is removed?

• A. ROM
• B. SSD
• C. HDD
• D. RAM is volatile memory that loses data when power is removed.

Answer: (D)

Volatile memory is designed to lose its contents when power is removed, and RAM is the primary example. RAM holds the data and programs the CPU works with right now, so it needs electricity to keep that information. When you shut down or power is lost, RAM clears its contents, which is why unsaved work is lost. In contrast, non-volatile storage like ROM, SSDs, and HDDs keeps data even without power. ROM stores firmware in a non-volatile form, and SSDs and HDDs are long-term storage for files and system data. So the memory that is typically volatile and loses data when power is removed is RAM.
