When does page fault occur?Given the 7 page reference strings 7, 0, 1, 2, 0, 3, 0, 4, 2, 3, 0, 3, 2, 3, find the number of page fault using Optimal Page Replacement, FIFO and Second Chance Replacement algorithm. Assume the size of page frame is 4.[1+9]

A page fault occurs when a process references a page that is not currently present in main memory (RAM). The CPU generates a trap, and the OS must bring the required page from secondary storage into a frame. If no free frame exists, a page replacement algorithm chooses a victim to evict. --- - Re...
