WebThe page fault primarily causes an exception, which is used to notify the operating system to retrieve the "pages" from virtual memory to continue operation. Once all of the data has been placed into physical memory, the program resumes normal operation. The Page fault process occurs in the background, and thus the user is unaware of it.
