6. A system adopts a priority-based preemptive scheduling and every process runs for 5 ms, before the dispatcher switches processes. In a recorded time span, the system has four processes, P1, P2, P3 and P4, as shown in the following table: Process ID Initial Priority Arrival Time in ms Total CPU Time in ms 0 5 10 15 P1 P2 P3 P4 1 3 2 2 15 7.5 5 10 Draw a timing diagram as explained in class for the above processes. Assume that the dispatcher takes 2.5 milliseconds for a process switch. Assume that the highest priority value is 0.
