Correct option is D
Read Only Memory (ROM) is non-volatile memory, meaning it retains its data even when the computer is turned off. It is primarily used to store firmware or permanent instructions for booting the system. Important Key Points:
1. ROM: A type of memory that contains data that can only be read, not written or modified.
2. Non-volatile Memory: It does not lose its contents when power is turned off.
3. Use in Computers: ROM stores essential instructions for starting the computer, such as the BIOS.
4. Firmware: ROM is often used to store firmware, which provides low-level control for devices.
Knowledge Booster:
· RAM vs. ROM: Unlike ROM, Random Access Memory (RAM) is volatile and is used for temporary data storage that is erased when the system is powered off.
