A page fault is a trap from the CPU to the Operating System that an address in virtual memory was not accessable. It is hoped that the Operating System will "page in" that location so that execution can continue. If the Operating System cannot provide a page for that location a SIGSEGV signal is sent to the process to stop execution.
