WebWhen a process requires a page that isn’t in the memory, a page fault occurs. A page replacement needs to be in action. Which page chooses FIFO (Lo et al 2001) to replace? FIFO selects the page that is entered the first in main memory. FIFO removes the page that is older. In Table 1 is shown how FIFO works. 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 front of the queue. The first page in the queue is chosen for removal when a page has to be replaced. scotch monthly clubWebFirst Come First Served (FCFS) is a Non-Preemptive scheduling algorithm. FIFO (First In First Out) strategy assigns priority to process in the order in which they request the processor. The process that requests the CPU first is allocated the CPU first. This is easily implemented with a FIFO queue for managing the tasks. scotch month club
