In computing, an '''interrupt''' is an asynchronous [[signal]] indicating the need for [[attention]] or a synchronous [[event]] in software indicating the need for a [[change]] in [[execution]].

A ''hardware interrupt'' causes the [http://en.wikipedia.org/wiki/Central_processing_unit processor] to save its state of execution and begin execution of an interrupt handler. Software interrupts are usually implemented as instructions in the instruction set, which cause a context switch to an interrupt handler similar to a hardware interrupt.
