Till now, we were scheduling the processes according to their arrival time (in FCFS scheduling). However, SJF scheduling algorithm, schedules the processes according to their burst time. In SJF scheduling, the process with the lowest burst time, among the list of available processes in the ready queue, is going to be scheduled next.

First Come First Serve (FCFS) is a CPU scheduling algorithm where the process that arrives first in the ready queue will be served first by the CPU. FCFS is a non-preemptive scheduling algorithm i.e. once the CPU is allocated to a process, the process releases the CPU only when the process gets terminated or it requests for I/O.

The round-robin (RR) scheduling technique is intended mainly for time-sharing systems. This algorithm is related to FCFS scheduling, but preemption is included to toggle among processes. A small unit of time which is termed as a time quantum or time slice has to be defined. A 'time quantum' is usually from 10 to 100 milliseconds.

The 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.
