Q. A page fault occurs (1 reply)
a) When page is in the memory
b) When the page is not in the memory
c) When the process is in the ready state
d) When the process enters the blocked status
I think this question is from bit higher conceptual topic of Operating Systems. I don't think it is suitable for operator preparation.
However, Page Fault is the technical term related to Virtual Memory Management. When processor looks for some page in real memory space and it can't find it there, a page fault occurs. VMM should catch this error from Operating system and look for it in virtual memory space. If it is there it is swapped in to the main memory and provided to the processor.
Hope this helps a bit?
