1. Consider the following set of processes with their alternating CPU-burst and I/O burst times given in time units: Process CPU I/O CPU I/O CPU P0 6 10 6 2 3 P1 2 12 2 5 4 P2 9 6 4 Assume all 3 processes

1. Consider the following set of processes with their alternating CPU-burst and I/O burst times given in time units: Process CPU I/O CPU I/O CPU P0 6 10 6 2 3 P1 2 12 2 5 4 P2 9 6 4 Assume all 3 processes have arrived in the order P0, P1 and P2 at time 0. Draw the Gantt charts for the CPU and for the I/O processing that shows the execution of these processes using FCFS scheduling. Calculate CPU Utilization, Average Turnaround Time, Average Wait Time in Ready, and Average Wait Time for the I/O Queue
