Page Replacement Algorithms in Operating System

WebFor example, in problem (a) the page size is 100, which means that requests 10 and 11 are on Page 0, and requests 104 and 170 are on Page 1. Therefore, the number of page frames is two. a.) Find the success frequency for the request list using a FIFO replacement Algorithm and a page size of 100 words (there are two page frames). b.) WebFIFO. The simplest algorithm for replacing pages is this one. The operating system maintains a queue for all of the memory pages in this method, with the oldest page at the …
