Question

What is the arrival time, completion time, burst time, turnaround time, and the waiting time for Priority Scheduling?

Answer 1

Arrival Time: The time at which the process arrives in the ready queue, is called ad Arrival time.

Completion Time: The time at which the CPU completes the execution of the process is called as Completion Time of that process.

Burst Time: It is the total time needed for the process to be executed completely, in other words- total time a process can have access to CPU is called as Burst Time.

Turn Around Time: Turnaround time (TAT) is the time interval from the time of arrival of a process to the time of the completion of the process.
In other words- It is the total amount of the time periods spent waiting to get into memory and executing.

Turn_Around_time = Completion_Time - Arrival_Time

Waiting Time: How much time processes spend in the ready queue waiting for their turn to get access of the CPU..

We can also describe it as the Time Difference between turn around time and burst time.
Waiting Time = Turn Around Time – Burst Time
