In multi-level feedback queue (MLFQ), how do processes with the same priority run?  Group of answer choicesFirst process run firstProcess with the shortest burst time left runs firstProcesses run in turns based on a time sliceProcess with shortest burst time runs last

In priority scheduling algorithm, when a process arrives at the ready queue, its priority is compared with the priority ofGroup of answer choicesall processparent processnone of thesecurrently running process

State one difference between a queue and a priority queue

A common strategy to give each process in the queue some time in turn is referred to as a __________ technique.Select one:A.round-robinB.time slicingC.serial processingD.multithreading

Consider the following set of processes, with the length of the CPU burstgiven in milliseconds:Process Burst Time PriorityP1 2 2P2 1 1P3 8 4P4 4 2P5 5 3The processes are assumed to have arrived in the order P1, P2, P3, P4, P5,all at time 0.a. Draw four Gantt charts that illustrate the execution of these processes using thefollowing scheduling algorithms: FCFS, SJF, nonpreemptive priority (a larger prioritynumber implies a higher priority), and RR (quantum = 2).b. What is the turnaround time of each process for each of the schedulingalgorithms in part a?c. What is the waiting time of each process for each of these scheduling algorithms?d. Which of the algorithms results in the minimum average waiting time (over allprocesses)?

Priority queue can be implemented using
