Assertion (A): In demand paging, a page fault occurs when a process attempts to write data to a read-only memory section.

Reason (R): A page fault is an explicit interrupt triggered by the MMU hardware when a referenced virtual page does not have its valid bit set in the page table.

Choose the correct answer:

Explanation

Assertion (A) is False: Writing to a read-only memory section causes a protection fault (or segmentation fault), not a page fault. A page fault happens when a required page is not loaded into physical RAM.
Reason (R) is True: A page fault is an interrupt generated by the MMU when a referenced virtual page lacks a valid bit set in the page table (meaning it is currently in secondary storage).

Correct Answer: (d) Assertion (A) is false, but Reason (R) is true.
