An operating system uses the Round Robin (RR) without priority CPU scheduling algorithm, with a quantum = 4.

Consider the following set of processes in this OS, with the length of the CPU burst time given in milliseconds, and the shown priority.

The processes are assumed to have arrived in the order P1, P2, P3, P4, P5, all at time 0.

Process Burst Time Priority
P1 5 2
P2 10 5
P3 4 1
P4 6 4
P5 9 3

a) Draw a Gantt chart illustrating the order of execution of these processes, showing their completion times.

b) Calculate each process’ waiting time, and then compute the average waiting time for this set.

Note:  waiting time = completion time – arrival time – burst time

=> Write your answers on scratch paper (make sure it is visible) then take a picture of it and upload it here.

List some processes (at least four) with the appropriate properties for creating a time diagram (such as Process ID, Arrival Time, Burst Time, and Execution Time). Walk through the timing diagram identifying the algorithm you’re using and state which process goes first, which process finishes first, etc.

The following processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm. Each process is assigned a numerical priority,with a higher number indicating a higher relative priority. The scheduler will execute the highest-priority process. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue. Process            Burst Time Arrival Time...
