    • That is, the interval from time of submission of the process to the time of completion of the process (Wall clock time).

    • The time from submitting a batch of punched cards for compilation, until the compiler’s output listing was available for pickup was the turnaround time.

    • Turnaround time is more of a range for example turnaround time 1 to 2 weeks.

  • Response time: -

    • Amount of time it takes from when a request was submitted until the first response is produced.

    • Remember, it is the time till the first response and not the completion of process execution (final response).
