the total time that staying in the queue that wait for process of each process.
why we use disk scheduling in c ?
Process waiting for an event that is not available or may be available in some time....
Round Robin
Average Turn Around Time = Completion Time - Arrival TimeAverage Waiting Time = Turn Around Time - Burst(execution) Time
Some other kinds of waiting in an operating system include waiting on applications, waiting on the user, and waiting for hardware to communicate. The operating system facilities many different components to work in sync.

There are a few key attributes of an operating system. The most common keys are scheduling, memory management and allocation of resources.

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.
the objective of multiprograming is to have some processs running at aal time,so as to maximizing cpu utillization .this process is called scheduling.
