Waiting Time is the difference between turnaround time and burst time Turnaround Time = completion of a process – submission of a process Turnaround Time is the time interval between the submission of a process and its completion. The only disadvantage of it is overhead of context switching.Ĭompletion Time is the time required by the process to complete its execution It follows preemptive approach because fixed time are allocated to processes. CPU treat ready queue as a circular queue for executing the processes with given time slice. Time quantum can range from 10 to 100 milliseconds.
A small unit of time is known as Time Quantum or Time Slice. It is more like a FCFS scheduling algorithm with one change that in Round Robin processes are bounded with a quantum time size. Round robin is a CPU scheduling algorithm that is designed especially for time sharing systems.
We are given with the n processes with their corresponding burst time and time quantum and the task is to find the average waiting time and average turnaround time and display the result.
