Consider the following set of processes, with length of CPU burst given in milliseconds:
Process
Burst Time
Priority
Order Arrived
P1
14
3
1
P2
7
1
3
P3
9

2
P4
14
5
4
P5
8

P6

5
Looking at FCFS, SJF, RR (quantum = 4), and non-preemptive priority (lower is higher priority), give the following
Average wait time for each process for each scheduling algorithm
Average turnaround time of each process for each of the scheduling algorithms
When looking at your results above; which is the “best” scheduling technique, and why? (The defense of your choice is what is being graded)
There is a demand-page system that has the following measurements:
CPU utilization: 8%
Paging disk (demand): 96.3%
Describe in general how the system is being used. (is it fast? Slow? User experience?)
Explain the effect on the above measurement (CPU utilization) if the following occurred:
Increase the page size
Add pre-paging
Increase RAM
Overclock the CPU
Install faster HDD
Make paging disk larger (increase size)
