Round Robin Process Scheduling algorithm in operating systems

Round Robin Scheduling

Round Robin Scheduling is the preemptive scheduling algorithm.

We assign a fixed time to all processes for execution, this time is called time quantum.

All processes can execute only until their time quantum and then leave the CPU and give a chance to other processes to complete their execution according to time quantum.

Context switching mechanism store the states of preempted processes.

Time quantum = 2

Process Burst Time Arrival
P1 4 2nd
P2 2 3rd
P3 8 1st
P4 3 4th
