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

The term that describes the duration from the submission of a process to its completion is known as turnaround time. This metric measures the total time taken to execute a particular process, encompassing all phases such as waiting in the queue, execution, and any potential delays. Turnaround time is crucial for understanding the overall performance and efficiency of a system in handling processes, as it provides insight into how quickly tasks are completed from the perspective of the user or application requesting the process.

In contrast, response time specifically refers to the interval between the submission of a request and the first response, which may not indicate the total time until completion. Waiting time is the amount of time a process spends waiting in the queue for CPU allocation, and process time generally refers to the actual time spent on executing a task without including wait times. Therefore, turnaround time is the most comprehensive term for the entire duration from submission to completion.
