• Interrupt — This article is about computer interrupts. For the study of the effect of disruptions on job performance, see Interruption science. In computing, an interrupt is an asynchronous signal indicating the need for attention or a synchronous event in… …   Wikipedia

• Interrupt handler — An interrupt handler, also known as an interrupt service routine (ISR), is a callback subroutine in an operating system or device driver whose execution is triggered by the reception of an interrupt. Interrupt handlers have a multitude of… …   Wikipedia

• Interrupt storm — In operating systems, an interrupt storm is an event during which a processor receives an inordinate number of interrupts that consume the majority of the processor s time. Interrupt storms are typically caused by hardware devices that do not… …   Wikipedia

• Interrupt latency — In Realtime Operating Systems, Interrupt latency is the time between the generation of an interrupt by a device and the servicing of the device which generated the interrupt. For many operating systems, devices are serviced as soon as the device… …   Wikipedia
