For the following processes, estimate average waiting time for priotiry scheduling combines with round robin scenario.Consiider quanta of 1s. Process Burst TimePriority P1 10 3 P2 1 P3 2 2 P4 1 Ps 2 P6 3

In Round Robin scheduling, when three processes have to enter the ready-queue at the same instant, if one process (A) has just finished 1/o, the other (B) has been pre-empted from CPU due to expiration of its time quantum and the third (C) has just started, which one will be inserted last (i.e. with lowest priority)? O The process that has just finished I/O. O One of the three will be randomly selected. O The process that has been pre-empted from CPU due to expiration of its time quantum. O The process that has just started.

Suppose there are four processes (P1 - P4) with respective arrival times of 0, 10, 30, and 40, and burst times of 30, 20, 50, and 20 ms. These processes are scheduled from a ready queue on first come first served. The average waiting time is?
Suppose that the following processes arrive for execution at the times indicated. Each process has the shown priorities and will run for the amount of time listed (all times are in ms) Process Arrival Time Burst Time Priority Queue P1 15 3 P2 20 3 P3 20 20 P4 25 10 2 P5 30 5 2 P6 35 15 1 To schedule the execution of these process, a preemptive multi-level queue scheduler is designed to apply the following policy at each decision instant (namely whenever a new process arrives and whenever a burst completes execution): • Serve the process at the highest priority queue first • If two processes are in the same queue: . If they have different remaining time, follow the SRTF policy o If they have same remining time, follow a RR policy (slice time = 2 ms) Given the above: 1. Show the scheduling order of the bursts using a Gantt chart.
Consider the following set of processes (a smaller priority number implies a higher priority). The processes are assumed to have arrived in the order P1, P2, P3, P4, P5 all at time 0. Process Priority Burst Time P1 1 20 P2 3 25 P3 4 25 P4 2 15 P5 5 30 What is the waiting time of each process for each of the scheduling algorithms FCFS, SJF (if two jobs have the same burst time, schedule them following priority), non-preemptive priority?

Given the following processes that arrived on the system as indicated in the table. The table also mention the burst time and priority of each one. Process Arrival time Burst time Priority P1 12 3 P2 7 1 P3 2 2 How the system will allocate the CPU based on Round Robin with time quantum equal to 3– suppose that all processes arrived at time 0. Processes are selected to enter the queue according to priority. So, instead of processes entering the queue in the order P1, P2 and P3. They will enter according to their priority from highest to Lowest. So, they will enter the queue in the order P2, P3, P1. Afterwards, you execute the Round Robins algorithm and draw the Gantt chart.
Concurrent Processes / Monitors select which is true options: a CV (condition variable) queues in a monitor store suspended processes waiting on the corresponding condition. b The "Signal and Wait" approach (Hoare semantics) leads to more efficient implementation and reduces the number of context switches. c Two or more processes can be active in the same monitor simultaneously. d When the "Signal and Continue"-approach (Mesa semantics) is applied, the signaling process P continues executing. e The monitor-based solution to the Dining-Philosophers problem discussed in class is restricted to 5 philosophers.
