Which term is defined as the time required to transport a change from one place to another?

The term that accurately describes the time required to transport a change from one place to another is encapsulated by "response time." This term refers to the time taken for a system or component to react and deliver the necessary feedback after an input or change is made. In contexts such as machinery operations or mechanical systems, response time is critical because it impacts the overall efficiency and effectiveness of the process.

Dead time, on the other hand, typically refers to periods during which no useful work is being done or when the system is inactive. Delay time can imply waiting periods that may involve various factors, but it does not specifically capture the idea of "transporting a change." Processing time relates to the actual time taken to perform a task or operation, which again is distinct from the movement or transportation aspect described in the question.

Therefore, response time is the most fitting term to describe the overall impact of time considerations related to transportation in a system context.
