Which memory type retains contents permanently and is burned either at the time it is manufactured or the time the computer parts are assembled?

• A. RAM
• B. Cache
• C. ROM
• D. Register

Answer: (C)

Non-volatile memory that preserves its contents without power is what this item describes, and that memory is ROM. ROM stores firmware or essential instructions and is typically written during manufacturing or assembly via fixed-programming methods like mask ROM or one-time PROM. Once written, it remains unchanged during normal use, so the data stays available even when the system is shut down. In contrast, RAM, cache, and registers are volatile and lose their data when power is removed, serving temporary or fast-access roles rather than permanent storage.
