The CPU and I/O times for 2 processes are shown below. Assume
that P1 gets to the ready queue just before P2 and the scheduling
algorithm used by the OS is Round Robin with a time slice of 3 time
units. Assume that the I/Os for the processes are different so that
there is no I/O queue. Assume also that an interrupt from a
completed IO for process "X" will place process "X" in the ready
queue BEHIND the process...

The following processes are being scheduled using a preemptive, roundrobin scheduling algorithm. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. In addition to the processes listed below, the system also has an idle task (which consumes no CPU resources and is identified as I ). This task has priority 0 and is scheduled whenever the system has no other available processes to run. The length of a time quantum is 5 units....

Given the following set of processes---with the specified length of the CPU burst, arrival time, and priority---compute response time for P1-P5 with round-robin scheduling with time quantum of 10 units. Also compute average response time. Assume that a newly arriving process arrives first at time T- and a process that is preempted due to the completion of its quantum arrives at time T+ in the waiting queue. (Note: Show the Gantt chart and other working details in your worksheet.) Process...
