Which statement differentiates primary storage from secondary storage with examples?

• A. Primary storage is non-volatile; secondary storage is volatile.
• B. Primary storage (RAM) is volatile memory used by the CPU for active tasks; secondary storage (hard drives, SSDs, USB drives) is non-volatile and stores data long-term.
• C. Primary storage is longer-lasting media; secondary storage is faster access.
• D. There is no difference between primary and secondary storage.

Answer: (B)

Primary storage vs secondary storage differ mainly in volatility, speed, and purpose. RAM, the primary storage, is volatile, meaning it loses its contents when power is off, and it is designed for extremely fast access so the CPU can read and write data during active tasks. Secondary storage devices—hard drives, SSDs, USB drives—are non-volatile, so data stays even without power, and they provide long-term storage for programs and files, though they’re slower to access than RAM. This combination explains why software is loaded from secondary storage into primary memory before the CPU can execute it: the long-term data sits safely on a persistent device, while the active work happens in fast, temporary memory. The idea that primary storage is non-volatile, or that secondary storage is faster, or that there’s no difference between the two, doesn’t align with how computers manage data and execution.
