WebDec 12, 2012 · FIFO is one method to determine what page will get removed. The concept is that whatever page got added first to the frame will get removed first. This is what FIFO stands for. Using your first example. I will go down the reference string list and show you what the memory will look like. 1: 1 +1 fault 2: 1,2 +1 fault 3: 1,2,3 +1 fault 4: 2,3,4 ... WebUsing FIFO with three frames, we incur 9 page faults (work this out!). With four frames, we incur 10 faults! It would be nice if buying more RAM gave us better performance.
