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
explain how response time are reduced by allowing time sharing on top of multiprogramming
Major page fault: If the page is not loaded in memory at the time the fault is stated, then it is named major or hard page fault. The handler in the machine requires to search a
Suppose a logic-based agent in the wumpus world has found that locations (1,1) and (2,1) do not contain a stench, but that locations (3,1) and (2,2) do contain a stench. Can the ag
