WebThe LRU page replacement algorithm keeps track of page usage in the memory over a short time period. In contrast, In the LFU page replacement algorithm, the page with the least visits in a given period of time is removed. LRU removes the page that has not been utilized in the memory for the longest period of time. WebApr 26, 2024 · Least Recently Used (LRU) page replacement algorithm In this algorithm, the new page is replaced with the existing page that has been used the least recently. In other words, the page which has not been referred for a long time will be replaced with the newly arrived page. This algorithm is just opposite to the Optimal Page Replacement algorithm.
