Program for fifo page replacement algorithm

WebThe enhanced second-chance page-replacement algorithm and the FIFO page-replacement algorithm are both page-replacement algorithms used in demand-paging systems. The main difference between the two algorithms is that the enhanced second-chance algorithm uses a reference bit and a modified bit to determine which pages to replace, while the FIFO ... WebThis is the simplest page replacement algorithm. In this algorithm, the operating system keeps track of all pages in the memory in a queue, the oldest page is in the front of the queue. When a page needs to be replaced page in the front of the queue is selected for removal. See also Solar Energy Computer Graphics Project in OpenGL.
