WebThe FCFS scheduling technique is the simplest scheduling algorithm. In this scheduling, CPU schedules the processes on the basis of their arrival time. The processes are stored in a queue that follows a First In First Out (FIFO) structure. When a process arrives, it takes the CPU time and runs till it completes.
