Step by step

- 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 FalseStride scheduling is in Section 9.6. Please read that section. Consider the following mix of jobs running on a system using stride scheduling: Job # 1 2 3 Stride 40 60 30 If we wish to add a job #4 that will run twice as often as job #1, what is an appropriate stride for the job?Write a program for implementing Round Robin (RR) scheduling and calculate the average waiting time. .
- In this project, you'll implement one of the following CPU scheduling algorithms by writing a CPU simulator. Shortest Job First (SJF)(Non-preemptive)The shortest job first algorithm is a priority based scheduling algorithm that associates with each process the length of the process's next CPU burst. When CPU is available, it is assigned to the process that has the smallest next CPU burst. Shortest Remaining Time Next (SRTN)(Preemptive)The shortest remaining process next scheduling algorithm is the preemptive Shortest Job First algorithm. With this scheduling algorithm, the process in the ready queue with the shortest execution time is chosen to execute. If a "new process" arrives in the ready queue with a CPU service time less than the remaining time of the current process, preempt. First Come First Serve (FCFS) (recommended)The first come first serve algorithm is simplest CPU-scheduling algorithm. In this algorithm, the process at the head of the queue is allowed to execute until it…So I need help with scheduling algorithm HW. So I attempted to do this myself and will drop my work in to see if anyone can correct it. First are the questions then the "attempted" work........2. a) Your colleague has invented a new scheduling algorithm using the multilevel queue approach. This list of processes showing CPU burst times is below. There are three queues used in the application. The processes all start on the first queue and receive upto 10ms of burst time. Once the process has received the 10ms on the first queue, if the process still requires burst time it is passed to the second queue where it receives upto 20ms. Once the process has received the 20ms on the second queue, if the process still requires burst time it is passed to the third queue where it receives CPU time until it is completed. The operating system will only start allocating CPU time to processes on the second queue when queue 1 is empty. The operating system will only start allocating CPU time to processes on the third queue when queue 2 is empty. Process Number P1 P2 P3 P4 Burst time (ms) 21 8 35 50 i) Does this algorithm give higher priority to any queue over the others and any processes…

Process Number P1 P2 P3 P4 Burst time (ms) 21 8 35 50 ii) Is it likely that any processes will suffer starvation?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.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
- 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)There are many possible CPU-scheduling algorithms. a. How could we select one particular algorithm for a particular system? b. Give some examples and discuss various evaluation methodsThe 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
