Page Replacement Techniques: A Review

Abstract

Page replacement algorithms are utilized for virtual memory the executives and it causes the OS to choose which memory page can be moved out, making space for the as of now required page. Each algorithm fulfills the objective of reducing the number of page faults and increase page hits in different manners that will increase the performance of the process. This paper tells about the main page replacement algorithms LRU, FIFO, optimal and also discuss some other algorithms like Second Chance Page Replacement, Clock Page Replacement and Not Frequently Used Page Replacement. An also discuss which is better and why and also it discusses the challenges in previous algorithms so we have done modification in them a produce new algorithm.
