Answer 2

FIFO algorithm is at type of frame on a page fault in which the frame remains in a memory until the longest is replaced.

1.FIFO algorithm is the basic and simplest page replacement algorithm.

2. In this algorithm, the operating system keeps a well developed sequence of all pages in the memory in a queue.

3.The oldest page remains in the front of the queue. And when a page needs to be replaced, the page which lies in the front of the queue is selected for removal.
