Q49 / 100
What is "virtual memory paging," and what is a "page fault"?
Correct! Well done.
Incorrect.
The correct answer is A) Paging divides memory into fixed-size blocks (pages) that can be mapped between physical RAM and disk; a page fault occurs when a program accesses a page not currently in physical memory, requiring the OS to load it from disk
A
Correct Answer
Paging divides memory into fixed-size blocks (pages) that can be mapped between physical RAM and disk; a page fault occurs when a program accesses a page not currently in physical memory, requiring the OS to load it from disk
Explanation
Paging allows the OS to use disk space as an extension of RAM; when a needed page isn't in physical memory (a page fault), the OS retrieves it from disk (swap/page file), possibly evicting another page to make room.
