Race condition is the scenario that the same problem can finish at different time when running at processors with different speeds or rates. O True O False When the total utilization of a given periodic task set is lower than 0.5, all tasks can meet their deadlines. O True O False There are in general two methods for interprocess communication: shared variable and The cyclic scheduling scheme is much simpler, more flexible, and adaptive than the round-robin scheduling scheme. O True O False Real time systems can be largely classified as soft real time systems and firm real time systems. O True he O False
Which of the following scheduling techniques is not a preemptive algorithm? What is the reason for this? a) Round Robin b) Multilevel Queue Scheduling c) First-In-First-Out d) Multilevel Queue Scheduling with Feedback a) Round Robin b) Multilevel Queue Scheduling with Feedback
Process Scheduling: Select all statements below that are true Dynamic Priority Round Robin (DPRR) makes use of a preliminary stage containing prioritized queues. When Multilevel feedback (MLF) scheduling is applied, processes at lower priority levels can take more processor time than processes at higher levels. Multilevel Priority (ML) scheduling is based on priority queues and uses a fixed set of priorities. When Multilevel Feedback (MLF) scheduling is applied, processes do not remain at the same priority level, but gradually migrate to lower levels each time they use up their allotted time threshold. Priority Inversion means that low-priority processes can be delayed or blocked by higher-priority processes.
The ready queue is subdivided into many queues by the multilevel scheduling algorithm, and each of these queues has its own scheduling technique or policy. Choose one: Is it accurate or erroneous? The time a process spends waiting should be minimised by the CPU scheduler. Choose one: OFalse O True
Q2) Which of the following scheduling algorithms is non-preemptive? And why?a) Round Robinb) Multilevel Queue Schedulingc) First-In First-Outd) Multilevel Queue Scheduling with Feedback

Using a number of different queues, each with its own scheduling strategy, is how the Multilevel scheduling algorithm works with the ready queue. Pick one: What's the deal? The time an individual process spends waiting should be minimized by the CPU scheduler. To choose one: The two alternatives are: FALSE or TRUE
Implement the following scheduling algorithms in C First-come, first-served (FCFS), which schedules tasks in the order in which they request the CPU. Shortest-job-first (SJF), which schedules tasks in order of the length of the tasks' next CPU burst. Priority scheduling, which schedules tasks based on priority. Round-robin (RR) scheduling, where each task is run for a time quantum (or for the remainder of its CPU burst). This is pre-emptive by default Priorities range from 1 to 10, where a higher numeric value indicates a higher relative priority. For round-robin scheduling, the length of a time quantum is 10 milliseconds. It never changes from this value.
2. Write programs in eitherCor Java or python (choose your preference ) to simulate the following scheduling Algorithms with their respective Gantt Charts displayed during run time: (i) FCFS- First Come First Serve Scheduling (ii) SJF- Shortest Job First Scheduling (Non - Preemptive and Pre-emptive both) (iii) LJB-Longest Job First Scheduling (Non - Preemptive and Pre-emptive both) (iv) Priority Scheduling (Non - Preemptive and Pre-emptive both)
