Process Scheduling: Select all statements below that are true The time quantum T for RR should be larger than the average CPU demand between two I/O operations (CPU burst) of 80% of the processes. Round Robin (RR) imposes a fixed time quantum (time slice) on the amount of continuous CPU time that can be used by a process. Shortest Job First (SJF) is a preemptive scheduling method. Waiting time refers to the time a processor spends in the ready state waiting for the processor. First-In / First-Out (FIFO) scheduling assigns higher priorities to processes that arrive earlier. Shortest Remaining Time (SRJ) is a nonpreemptive version of SJF.

Please Implement in C programming Language Given the list of processes, their CPU burst times, arrival times, and priorities implement the Priority scheduling algorithm on the processes with preemption. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Waiting time: Processes need to wait in the process queue before execution starts and in execution while they get preempted. Turnaround time: Time elapsed by each process to get completely served. (Difference between submission time and completion time).
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
Let the processes P1, P2, P3, and P4 be given. They arrive in the system at the same time in this order. The processes have the following service times (in time units): Process Service time (CPU burst) P1 53 P2 17 P3 68 P4 24 2) For the scheduling method "Round Robin" (RR), specify the average execution time (average turnaround time) and the number of context switches. The time quantum q is set to 20 time units. You must show your calculations. You will not have to draw Gantt charts. Note: For RR, processes execute in order of their ID (i.e., P1-P2-P3- P4).

Answer the following sentences true or false 1. Looping is basically a phase in which we repeat the very same process multiple times u less it specifies any specific type of condition. 2. An infinite loop(sometimes called an endless loop) is a piece of coding that lacks a functional exit so that it repeats indefinitely. 3. In while loop, a condition is evaluated before processing a body of the loop.
Write a C++ or Java program to simulate the following non-preemptive CPU scheduling algorithms to find turnaround time and waiting time. a) FCFS b) SJF c) Round Robin (pre-emptive) d) Priority *Write a C++ or Java program to simulate multi-level queue scheduling algorithm considering the following scenario. All the processes in the system are divided into two categories – system processes and user processes. System processes are to be given higher priority than user processes. Use FCFS scheduling for the processes in each queue.

Implement Round Robin scheduling algorithm in C programming. NOTE: Please do not compute and print the average waiting time and the average turnaround time. You are required to compute these for each process and print these times for each process separately. Add comments in the code so that the code is understandable. Take input from the user: the number of processes, the time quantum and their CPU burst times for n number of processes. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Assuming all the processes have arrived at time 0, please do not take arrival times as input from the user.
