If an application requires more physical memory it uses swap memory. Page out means moving some data and address space of physical memory to hard disk.A page fault happens when a system tries to access data in memory that has been paged out to disk.

The number of times that data had to be retrieved from the page file
on the hard disk  because it had been paged out of
physical memory. Windows  uses a page file stored
on the hard disk to augment physical memory. When the physical
memory is full, Windows swaps older information in physical memory
to the swap file to make room for newer information. Too many
page faults often indicate that you need more physical memory.
