WebSep 30, 2024 · The simplest page-replacement algorithm is a FIFO algorithm. The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires little bookkeeping on the part of the operating system. In simple words, on a page fault, the frame that has been in memory the longest is replaced. ... No. of page faults. Example ... WebFeb 4, 2024 · 1. LRU is like FIFO, except when something in the queue is referenced, it gets moved to the back of the queue. So you need to find a sequence where by moving one item (A) to the back of the queue, LRU chose to evict (B) whereas FIFO evicted (C), then (B) appeared in the sequence before (A), so LRU had to re-fetch (B) while FIFO didn't. – … irs deadlines for tax year 2022
