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