• 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

• 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 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
