WebNov 4, 2024 · No, FCFS is not suffering from starvation because the order of execution is fixed on the basis of the arrival time of the processes. Suppose, P0 arrives at 0 and P1 arrives at 1 and P0 is a low priority but in FCFS, P0 will schedule first then P1. Starvation is possible when we do preemptive scheduling of the process.
