Consider this table when answering the following questions about scheduling. The table shows a list of processes P1 through P5. For each process, the total running time is given in the table. For example, if process P3 was given the CPU at time t, and was allowed to run to completion without being interrupted, it would finish at time (t+12) Process P1 P2 P3 P4 P5 Total Running Time 26 12 6 18 A schedule for tasks can be shown as a chart. For instance, if processes P2, P4, P3 arrive in that order and the OS processes them using a first come, first served schedule, the schedule of tasks would be as follows: running Note that in the above schedule, process P2 does not have to wait. It gets the CPU immediately (i.e at time-0). Process P4 has to wait for 3 units of time (while process P2 finishes) and process P3 has to wait 9 units of time (while P2 and P4 finish)
