What are the relationships between priority and FCFS of CPU scheduling algorithms?
this is my doubt about the non-preemptive priority scheduling. i m doing bachelor of engineering in IT and this question in end semester exam. the question is as follows:Assume you have the following jobs to be executed with one processor, with the jobs arriving in the order listed here:Process Burst Time PriorityP1 80 5P2 20 1P3 10 3P4 20 2P5 50 4Suppose the system uses priority scheduling. Draw Gantt chart and calculate average waiting time for the processes.My doubt is:suppose if we were to use non-preemptive priority scheduling, the question says the jobs arriving in the order listed, so as per the order P1 will arrive first so it will get the CPU first and in non-preemptive once a job gets CPU it will not leave CPU till the process finishes, then as per the order P2 will come and same thing repeats.... so it acts like FCFS scheduling and priority is of no use here. But my lecturer says we have to follow the priority and P2 will come first, but the line the jobs arriving in the order listed is still not letting me agree with my lecturer. Can anyone help out?

How do you calculate the average waiting time and turnaround times of a operating system ptdf?
To calculate the average waiting time and turnaround time in a process scheduling algorithm like Preemptive Time Division Fairness (PTDF), first determine the completion time for each process. The turnaround time is computed as the difference between the completion time and the arrival time of each process. The waiting time is found by subtracting the burst time from the turnaround time for each process. Finally, average these values by summing them up and dividing by the number of processes.
