Assertion (A) and Reason (R) Analysis

Analyzing Assertion (A): ROM Data Retention

Assertion (A) states that Read Only Memory (ROM) does not lose its data after restarting the computer system.

  • ROM is a type of non-volatile memory.
  • Non-volatile memory retains stored information even when not powered.
  • Therefore, restarting the computer does not erase the data stored in ROM.

Conclusion: Assertion (A) is correct.

Analyzing Reason (R): Non-Volatile Storage Definition

Reason (R) states that a non-volatile storage unit loses data stored in it in case of power off or interruption of power.

  • The defining characteristic of non-volatile storage is that it *retains* data without power.
  • Conversely, volatile storage (like RAM) loses data when power is turned off.
  • Reason (R) incorrectly describes the behavior of non-volatile storage; it actually describes volatile storage.

Conclusion: Reason (R) is incorrect.

Final Conclusion

Based on the analysis:

  • Assertion (A) is correct.
  • Reason (R) is incorrect.

This corresponds to the option stating that (A) is correct but (R) is not correct.
