Previous Year Question
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
Correct Answer: C
Detailed Solution
ROM stands for Read Only Memory. It is a type of Non-Volatile Memory.
The characteristic of non-volatile memory is that the stored information is retained even when the power supply is switched off.
ROM generally stores instructions or data required for the basic operations and startup process of a system.
In contrast, RAM (Random Access Memory) is volatile memory. When the power supply is switched off, the data temporarily stored in RAM is generally lost.
Therefore, the memory that retains its contents even when the power supply is interrupted is ROM.
