What is interrupt latency?

In computing, Interrupt latency means the period that passes from during an interrupt is produced during the origin of the interrupt is sustained. For various operating arrangements, tools are sustained as shortly as the machine's interrupt handler is administered.

Interrupt latency, which is further called interrupt answer period, is the measure of the period that it uses for a workstation interrupt to be worked on later it has continued to generate. In most workstations, a trade-off subsists among interrupt latency, processor utilization, and throughput. Thus, Interrupt latency signifies the time that transpires amid the event of an intervening appeal and the following performance of the initial guidance of the corresponding interrupt service method.
