Consider the following set of processes, the length of the CPU burst time given in milliseconds: Process Burst time: P1 6 P2 8 P3 7 P4 3 Assuming the above process being scheduled with the SJF scheduling algorithm: The waiting time for process P1 is 3ms.

Let the processes P1, P2, P3, and P4 be given. They arrive in the system at the same time in this order. The processes have the following service times (in time units): P2 17 Process Service time (CPU burst) P1 53 P3 68 P4 24 For the scheduling method "Shortest Job First" (SJF), specify the execution order of the processes, the average execution time (average turnaround time) and the average waiting time over all processes. You must show your calculations. You will not have to draw Gantt charts.

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 0 being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict. Also,…

(For the following short questions, provide a 3-4-line answer. The answer should be based on your analysis and critical thinking) Consider there are two set of processes Set1 has processes with longer burst times than Set2. The operating system is implementing Shortest Job First (SJF) for Scheduling. Which SJF approach is suitable for Set1 and Set2 (choose from Preemptive and Non-Preemptive). Justify your answer. Can we improve overall process execution performance by increasing RAM size? What are the pros and cons of increasing RAM size? What is the role of IO devices in process execution? What are the reasons for a process to exit from running state other than it finishes? If OS claims provision of protection and sharing mechanisms at the same time, do these mechanisms not violate the purpose of each other? Justify. Why is synchronization necessary among processes when all of them are executing on a single CPU machine and only one of them can actually execute at any one moment?…
