A characteristic of ROM is that it is:
Correct answer: B. Non-volatile
- A. Volatile
- B. Non-volatile
- C. Costy
- D. Less available
Explanation
This is the correct answer. Non-volatile memory, like ROM, can retain its data even when the power is turned off. This makes ROM suitable for storing permanent data, such as the BIOS (Basic Input/Output System) that is used to start the computer.In summary, the key characteristic of ROM is its non-volatile nature, meaning it retains data even without power. The other options (volatile, costly, less available) are not defining properties of ROM.
