Which device is typically used for long-term data storage?

• A. Hard drive
• B. RAM
• C. Cache
• D. CPU

Answer: (A)

Long-term data storage means keeping data intact after the computer is powered down, so the data must reside on non-volatile media. RAM and cache are volatile; they hold information only while power is on and are used to speed up active tasks, not to preserve files over time. The CPU is a processor, not storage. A hard drive stores data magnetically on spinning disks and retains it without power, making it the typical choice for storing large amounts of information over the long term. (Solid-state drives also provide persistent storage, but hard drives are the traditional solution for long-term storage.)
