Final answer:
To calculate average turnaround time, obtain the completion time of each process, subtract the arrival time to find each process's turnaround time, sum these, and then divide by the number of processes.
Step-by-step explanation:
To calculate the average turnaround time for different schedulers in a computing environment, you must first understand that turnaround time is the total time taken from the submission of a process to the completion of the process. This includes all the time taken for waiting, executing on the processor, and any other delays.
To calculate the average turnaround time, follow these steps:
- Identify the completion time for each process, which is the point at which the process finishes execution.
- For each process, subtract the arrival time from the completion time to get the individual turnaround time.
- Add up all the individual turnaround times for all the processes you have.
- Divide the sum of all turnaround times by the number of processes to find the average turnaround time.
For example, if you have three processes with turnaround times of 4, 3, and 7 minutes, the average turnaround time would be (4+3+7)/3 = 4.67 minutes.
