Complete a Partial Gantt chart for MLFQat least 153 TIME UNITS

Calculate the PARTIAL results for Response Time (RT) , Waiting Time (WT), Turnaround Time (TT)PER PROCESS and Averages as of time 153 for MLFQ

Multilevel Feedback Queue (preemptive absolute priority in higher queues) Queue 1 uses RR scheduling with Tq = 6 Queue 2 uses RR scheduling with Tq = 12 Queue 3 uses FCFS All processes enter first queue 1. If time quantum (Tq) expires before CPU burst is complete, the process is downgraded to next lower priority queue. Processes are not downgraded when preempted by a higher queue level process. Once a process has been downgraded, it will not be upgraded.

Assumptions:

1.All processes are activated at time 0 2.Assume that no process waits on I/O devices. 3.After completing an I/O event, a process is transferred to the ready queue. 4.Waiting time is accumulated while a process waits in the ready queue. 5.Turnaround time is a total of (Waiting time) + (CPU burst time) + (I/O time) 6.Response time is the first measure of waiting time from arrival at time 0 until the first time on the CPU
