WebIn these cases, FCFS is an economical method of diskscheduling. But LOOK is nearly as easy to program and will give muchbetter performance when multiple processes are performing concurrentI/O, such as when aWeb browser retrieves data in the background whilethe operating system is paging and another application is active in theforeground. WebFirst-come-first-served (FCFS) scheduling can lead to starvation if a process with a long execution time arrives first and other processes with shorter execution times are continually added to the queue. These shorter processes will have to wait a long time before they are executed, which can cause them to starve. glory supermarket ad
