Pls help, Five batch jobs A through E arrive at a computer centre at essentially the same time. They have an estimated running time of 14,8,2,5 and 11 minutes respectively. Their externally defined priorities are 5,2,6,8, and 3 respectively, with a lower value being a higher priority. For each determine the turnaround time for each process and the average turnaround for all jobs. Ignore process switching overhead. In the last 3 cases assume only one job at a time runs until it finishes, and all jobs are cpu bound.

A. round robing with a time quantum of 1 minute

b.priority scheduling

c.FCFS ( in order 14,8,2,5, and 11)

d.Shortest first

Please explain so i can understand how its working as I am having trouble conceptualizing and going through.
