In memory management, page replacement is key when a page fault occurs. If no free memory is available, a page replacement algorithm like Optimal, FIFO, or LRU is used to replace a page, storing the ...

Optimal Page Replacement In this algorithm, pages are replaced which would not be used for the longest duration of time in the future.

Virtual memory management uses paging in any operating system, the page replacement algorithm uses to decide which memory pages are to swap out, which depends on the number of page faults. Each ...
