whats a "memory page faults"

Hi all. Dorky question , but I am still relatively new to the world of
ms database servers so bare with me. I am monitoring the page fault
rate on a server and it runs at 100% almost all of the time. Can
someone help me understand what that means?

A page fault is when a memory page is not where it's expected to be, and the
data has to be read/updated in another memory location, or from the hard
drive. More information here:
