Assume you have the following jobs to execute with one processor, with the jobs arriving in the the order listed here:

(i) Suppose a system uses RR scheduling with a quantum of 15. Create a Gantt chart illustrating the execution of these processes?

(ii) What is the turnaround time for process p3?

(iii) What is the average wait time for the processes

Round Robin (RR) CPU Scheduling

• In RR scheduling CPU is assigned to the process based on FCFS for a fixed amount of time called time quantum.
• After the time quantum expires, the running process is preempted and sent to the ready queue.
• Then, the processor is assigned to the next …
