Which statement about non-volatile data is true?

• A. Non-volatile Data is stored in RAM
• B. Non-volatile Data is used for temporary caches
• C. Non-volatile Data is used for secondary storage
• D. Non-volatile Data is transient

Answer: (C)

Non-volatile data is information that remains stored even when power is removed. To achieve this persistence, it’s kept on non-volatile storage devices, which are typically referred to as secondary storage. This category includes hard drives, solid-state drives, USB flash drives, and other long‑term storage media. Because these devices are designed to retain data without power, they’re used for storing files, operating systems, and archives. The other statements describe volatile memory or transient behavior. RAM and caches are designed for fast access and are powered by electricity, so they lose their contents when the system powers down. The idea of non-volatile data being transient contradicts the fundamental meaning of non-volatile: persistence beyond power cycles.
