Question

Given below are two statements: Assertion (A): A Read only memory (ROM) does not lose its data after restarting the computer system. Reason (R): A non-volatile storage unit loses data stored in it in case of power off or interruption of power. Choose the most appropriate answer.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Volatile memory loses data after power off; non-volatile memory retains data after power off.

Answer 1

The Correct Option is C

ROM stands for: \[ \text{Read Only Memory}. \] ROM is non-volatile memory. Non-volatile memory means memory that does not lose data when the power is turned off. So, when a computer is restarted, the data stored in ROM is not lost. Therefore, Assertion (A) is correct. Now check Reason (R). Reason (R) says that non-volatile storage loses data when power is off. This is wrong. Actually, volatile memory loses data when power is off. RAM is an example of volatile memory. ROM is an example of non-volatile memory. Therefore, Reason (R) is incorrect. Hence, the correct answer is: \[ \text{(A) is correct but (R) is not correct}. \]
