Define FIFO Page Replacement Algorithm
This policy simply eliminates pages in the order they arrived in the main memory. By using this policy we simply remove a page based upon the time of its arrival in the memory. For instance if we comprise the reference string that is: 1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5 and 3 frames (3 pages can be in memory at a time per process) after that we have 9 page faults as shown
