response time

(computer science) The delay experienced in time sharing between request and answer, a delay which increases when the number of users on the system increases.
(control systems) The time required for the output of a control system or element to reach a specified fraction of its new value after application of a step input or disturbance.
(electricity) The time it takes for the pointer of an electrical or electronic instrument to come to rest at a new value, after the quantity it measures has been abruptly changed.

The period between the application of a stimulus and the response of a cell or tissue.

In an ice mass, the speed of reaction to a change in its environment. In general, the smaller the ice mass, the faster the response. Thus, typical response times are: ice sheet, 100 000 to 10 000 years; large valley glacier, 10 000 to 1000 years; small valley glacier, 1000 to 100 years.

The time interval from the presentation of a stimulus to the completion of a movement; it is the sum of reaction time and movement time.

The noun has one meaning:

Meaning #1: the time that elapses between a stimulus and the response to it
