a) Why do we need scheduling in operating system? b) Consider the following set of processes in Table 1, with the length of the CPU-burst/cycle/time given in milliseconds and the priority. Process Arrival Time A C D 0 2 3 6 Table 1 CPU Cycle 5 4 6 4 [1 Marks] Priority 3 4 2 i. Draw a timeline chart to illustrate the execution of the above processes using Priority scheduling (preemptive) (smaller number implies higher priority). [3 Marks] ii. Complete Table 2 for the Priority scheduling. Show your calculation. Table 2 Process A B с D Waiting Time Average Waiting Time (AWT): Average Turnaround Time (ATT): Turnaround Time a) Why do we need scheduling in operating system? b) Consider the following set of processes in Table 1, with the length of the CPU-burst/cycle/time given in milliseconds and the priority.
