![]() ![]() ![]() Since no other process is available hence this will be scheduled till next job arrives or its completion (whichever is lesser).Īt time 1, P2 arrives. Process IdĪt time 0, P1 arrives with the burst time of 1 units and priority 2. Their respective priorities, Arrival Times and Burst times are given in the table below. There are 7 processes P1, P2, P3, P4, P5, P6 and P7 given. Once all the jobs get available in the ready queue, the algorithm will behave as non-preemptive priority scheduling, which means the job scheduled will run till the completion and no preemption will be done. The difference between preemptive priority scheduling and non preemptive priority scheduling is that, in the preemptive priority scheduling, the job which is being executed can be stopped at the arrival of a higher priority job. The One with the highest priority among all the available processes will be given the CPU next. ![]() In Preemptive Priority Scheduling, at the time of arrival of a process in the ready queue, its Priority is compared with the priority of the other processes present in the ready queue as well as with the one which is being executed by the CPU at that point of time.
