Consider the following process arrival, CPU and I$/$O burst times, and priorities given in the table

below. Consider $1$ as the highest priority.

Assume that only one I$/$O device is available and it operates in FCFS manner without context

switch time.

Assume that there is only one CPU and it is scheduled using preemptive Round Robin with

quantum $=3ms$ with context switch $=1ms.$

Draw CPU and I$/$O Gantt Chart, and then find Average waiting time, and average response time,

and turn around time and cpu utilization. Show your calculations in details.
