Consider the following processes. Calculate the average waiting times. Average response times, and Average turnaround times As described in class - all processes are initialized as Q1 processes, if the process is preempted for Tq it is moved to Q2. if it is preempted from Q2 it is moved to 93 MLFQ (Multilevel Feedback Queuel Q1 - RR - T (3) (preemptive priority over Q2 and 23) Q2-RR-TA (5) (preemptive priority over Q3) Q3.
