A page fault occurs when an access to a
page that has not been brought into main memory takes place. The operating
system verifies the memory access, aborting the program if it is invalid. If it
is valid, a free frame is located and I/O is requested to read the needed page
into the free frame. Upon completion of I/O, the process table and page table
are updated and the instruction is restarted.
