Which type of storage is typically used for long-term data retention on a computer?

• A. Primary storage
• B. Secondary storage
• C. RAM
• D. Cloud storage

Answer: (B)

Long-term data retention depends on non-volatile storage, so data stays even when the computer is off. Primary storage, like RAM, is fast but volatile; it loses everything when power is removed, so it’s used for active processing, not for keeping files long-term. Secondary storage includes hard drives and solid-state drives, which hold data without power and provide the larger, persistent space needed for documents, programs, and system files. Cloud storage also preserves data, but it’s external to the computer and relies on internet access, not the usual internal storage you rely on for everyday storage. So, for typical long-term retention on a computer, secondary storage is the standard choice.
