WebMar 25, 2024 · Apply First-In-First-Out (FIFO), Optimal, and Least Recently Used (LRU) Page Replacement Algorithms in a given reference string and the number of page frames to be … WebQuestion. Write a program that implements the FIFO, LRU, and optimal page-replacement algorithms presented in this chapter. First, generate a random page-reference string where page numbers range from 0 to 9. Apply the random page-reference string to each algorithm, and record the number of page faults incurred by each algorithm.
WebOptimal Page replacement: Here, when a page replacement is needed, it looks ahead in the input queue for the page frame which will be referenced only after a long time. The page with the longest reference is swapped. No. of page hit=6. No. of page miss=7. LRU page replacement: This method uses the recent past as an approximation of near future. WebJul 22, 2024 · This is a program that implements the FIFO, Optimal, MFU, and LRU page-replacement algorithms. Given a page-reference string, where page numbers range from 0 to 9, it applies the page-reference string to each algorithm and outputs the page-faults incurred by each algorithm.

WebVarious differences between the LRU and LFU Page Replacement Algorithm are as follows: LRU stands for the Least Recently Used page replacement algorithm. In contrast, LFU stands for the Least Frequently Used page replacement algorithm.
