What happens during a computer memory 'Page Fault' scenario?
A. The system architecture detects an invalid alphanumeric input string.
B. The CPU requests a data block from logical memory that is not currently loaded into physical RAM.
C. A sector on the hard disk drive undergoes permanent mechanical erosion.
D. The physical memory chip catches fire due to over-voltage.
Answer: Option B
Solution (By JKSSB Mock Tests)
A page fault occurs when a running program attempts to access a memory page mapped into its virtual address space, but that page is not presently resident in physical RAM.
Explanation:
Flash memory has a finite number of program/erase cycles, affecting SSD lifespan. It is non-volatile, faster than HDDs, and typically more expensive per GB.
