What is the term used to describe the time from submission to completion of a process?

• A. Response Time
• B. Turnaround Time
• C. Completion Time
• D. Process Time

Answer: (A)

The term that describes the total time taken from the submission of a process to its completion is known as Turnaround Time. This includes all phases of the process's life cycle, from the moment it is submitted to the system until it has completed execution and any necessary output is produced. Turnaround Time is a critical metric in operating systems, as it provides insight into how efficiently processes are being handled. It incorporates waiting times, execution times, and any other delays that might occur during a process's lifespan. Therefore, understanding this term is essential for analyzing and optimizing performance in operating systems. Response Time, while related, specifically refers to the period from request submission to the first output being produced. This does not account for the total time taken to complete the entire process. Completion Time and Process Time do not accurately capture the concept as defined, as they focus on specific phases or durations rather than the total duration from submission to completion.
