In a computing center there are four types of jobs according to their arrival times (in seconds), their priorities and their run times (in sec- onds); see the table below: Type 1 | Type 2 Type 3 Type 4 arrival time40 priority run time 40 0 0 0 2 50 There are 20 Type 1 jobs, 40 Type 2 jobs, 60 Type 3 jobs and 80 Type 4 jobs. Compute the average turnaround time using the mul- tilevel queues (round robin on every priority level the higher the priority, the sooner they run) scheduling algorithm. Use a quantum that provides short response time.]
