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
What is dispatch latency? The time taken by the dispatcher to stop one process and begin another running is known as dispatch latency.
Question : a) Consider table 1.0 below, assume the processes arrived in the order P 1 , P 2 , P 3 , P 4 at time shown and need the indicated burst time (both in milliseconds)
