Which is the best data structure for round robin algorithm for CPU scheduling?
Click to see full answer
Accordingly, what is round robin algorithm in operating system?
Round Robin is a CPU scheduling algorithm where each process is assigned a fixed time slot in a cyclic way. One of the most commonly used technique in CPU scheduling as a core. It is preemptive as processes are assigned CPU only for a fixed slice of time at most.
One may also ask, how do you find the waiting time in round robin? You can calculate Waiting time by drawing Gantt chart so waiting time of ith process is equal to Completion time - (Arrival time + Burst time ) . P1's last start time is 24 (when P1 running for 3rd time in Gannt chart) P1 preempted 2 times in it's lifetime Quantum = 4, Arrival = 0.
Also, which algorithm is best in CPU scheduling?
The most optimal scheduling algorithm is :
- (A) First come first serve (FCFS)
- (B) Shortest Job First (SJF)
- (C) Round Robin (RR)
- (D) None of the above.
What is round robin scheduling with example?
Round Robin Scheduling is a CPU scheduling algorithm that assigns CPU on basis of FCFS for fixed time called as time quantum. Round Robin Scheduling Example. Round Robin Scheduling is FCFS Scheduling with preemptive mode.
