WebFCFS (First Come First Serve) scheduling program in C FCFS (first come, first serve) is a CPU scheduling algorithm, in which allocation of CPU is on the basis of FCFS, the process which comes first will get the CPU first. It is non-preemptive scheduling. FCFS with arrival time and completion time WebFCFS uses non-preemptive scheduling, which means that once a CPU has been assigned to a process, it stays assigned to that process until it is either not terminated or may be …

WebIf the CPU scheduling policy is FCFS and there is 1 unit of overhead in scheduling the processes, find the efficiency of the algorithm. Solution- Gantt Chart- Here, δ denotes the context switching overhead. Now, Useless time / Wasted time = 6 x δ = 6 x 1 = 6 unit; Total time = 23 unit; Useful time = 23 unit – 6 unit = 17 unit Efficiency (η) WebMar 31, 2024 · FCFS (First-Come, First-Served) is a scheduling algorithm used in operating systems to manage the execution of processes or tasks in a queue.
