interrupt

v. stop, discontinue; disturb, interfere; interrupt the conversation or action of another (especially with a remark)

n. signal sent to the processor which tells the processor to deal with a certain event (Computers)

In computing, an interrupt is an asynchronous signal from hardware indicating the need for attention or a synchronous event in software indicating the need for a change in execution. A hardware interrupt causes the processor to save its state of execution via a context switch, 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. Interrupts are a commonly used technique for computer multitasking, especially in real-time computing. Such a system is said to be interrupt-driven.
