Question

Part IV: Scheduling.
Suppose that processes P1, P2, ..., P4 arrive for execution at the times indicated in
Table below. Each process will run for the amount of time listed, and will be assigned a
priority ranging from 0 (highest) to 10 (lowest). No more processes will arrive until the
last process completes. In answering the questions, base all decisions on the
information you have at the time the decision must be made.

In terms of their primary function, there are distinctions between "many threads" and "many processes". If it is not overly burdensome, it would be highly advantageous if you could provide further elucidation on this matter within a concise and succinct manner. I would greatly appreciate your assistance indefinitely.
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,…
