If any lab task asks to install any software and you are concerned about installing any of the software in these labs on your regular computer, you can instead install the software in a virtual machine you create using a hypervisor of your choice. Software installed within the virtual machine will not impact the host computer.

Jobs $-$ Order of ProcessingFive jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A$52$ m s $,$ Job B$512$ m s $,$ Job C$515$ m s $,$ Job D$57$ m s $,$ and Job E$53$ ms$.$

a$.$ Using FCFS$,$ in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for each of these five jobs?$$

b$.$ Using SJN$,$ and assuming that all jobs are present when the algorithm begins, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for all five jobs?$$

c$.$ Using SJN$,$ and assuming that all jobs are present when the algorithm begins, what is the average turnaround time for all five jobs using these speeds: Job A$512$ ms$,$ Job B$52$ ms$,$ Job C$515$ m s $,$ Job D$57$ m s $,$ and Job E$53$ m s$.$

Jobs $$ Start time, Finish timeUsing SJN$,$ calculate the start time and finish time for each of these seven jobs that arrive one CPU cycle apart. Then indicate the order in which the jobs run to completion. It might help to draw a timeline to understand when jobs arrive and finish.
