(d) On a system using 4 level feedback queues, a totally CPU-bound process requires 26 milliseconds to execute. If the first queue uses a time quantum of 1ms, the time quantum will be increased by 2 at each lower level. (i) What is the objective of this scheduling policy? (1 mark) (ii) How many times will the job be interrupted and on what queue will it be when it terminates? (1 mark) (iii)If the context switch takes 2 milliseconds, what will be the turnaround time of the process? (2 marks)
