Q. The content of computer memory which is non-volatile, even when the power goes off, is:
a) REM
b) RAM
c) ROM
d) None of the above
Question from UPPSC Prelims 2024
Correct Answer: c) ROM
Explanation:
– ROM (Read-Only Memory) is a type of non-volatile memory, meaning it retains its data even when the power is turned off. It is used to store firmware or permanent instructions that are essential for the computer’s operation, such as the BIOS (Basic Input/Output System).
– RAM (Random Access Memory), on the other hand, is volatile memory, which means it loses all its data when the power is turned off. RAM is used for temporary storage of data and instructions that the CPU needs while performing tasks.
– REM is not a valid term in the context of computer memory.
– None of the above is incorrect because ROM is the correct answer.
