Question: 1. Suppose that the following processes arrive for execution at the times indicated. Each process will run for the amount of time listed. In answering

1. Suppose that the following processes arrive for execution at the times indicated. Each process will run for the amount of time listed. In answering the questions, use non-preemptive scheduling, and base all decisions on the information you have at the time the decision must be made. (40 pts) Process Arrival Time Burst Time P P2 P3 0.0 0.4 0.8 2 6 3 2 4 P4 (a) Draw Gantt chart illustrating the execution of processes and calculate average waiting time and average turnaround time for these processes with the FCFS (First Come First Serve) scheduling algorithm. (7 pts) (b) What is the average turnaround time for these processes with the SJF (non-preemptive) algorithm? (7 pts)
