Eight batch jobs arrive almost at the same time in the following order: I₁, 2, ..., II8. The table below contains their running times and priorities: Job П1 П2 П3 П4 П П П П Running time (in min) 4 5 5 10 8 10 7 Priority 1 7 5 2 8 6 4 3 The highest priority is 1. For each of the following scheduling algorithms, determine the order of execution of processes and the mean process turnaround time: (a) priority scheduling; (b) first-come, first-served; (c) shortest job first. Scheduling is non-preemptive.

You need to perform, FEL, Service Time, Idle/Busy Status, Queue Length, and so on.
Let the processes P1, P2, P3, P4, and P5 be given. They arrive in the system at the same time in this order. The processes have the attached service times (in time units) and priorities. For each of the scheduling methods (First Come, first served (FIFO), Shortest Job First, Round Robin, and Priority Scheduling), specify the execution order of the processes and the average execution time (average turnaround time) for all processes. First, determine and state the execution times of the individual processes and then calculate the average value. Note: • For Shortest Job First, If the required service time (CPU time) is the same for two or more processes, use First Come, first served to resolve the conflict. • For Round Robin, the time quantum q = one time unit. • For Priority Scheduling, low integer priority values signify high priorities, with O being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict. Also,…
