Explain FIFO Page replacement algorithm.
FIFO policy: This policy only removes pages in the order they entered in the main memory. By using this policy we simply eliminate a page based upon the time of its arrival in the memory. For illustration if we have the reference string: 1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5 and 3 frames here 3 pages can be in memory at a time per process, after that we have 9 page faults as demonstrated:
If frames are increased say to 4, after that number of page faults also arises, to 10 in this case.
