http://www.linfo.org/software_interrupt.html WebAn interrupt is a signal emitted by hardware or software when a process or an event needs immediate attention. It alerts the processor to a high-priority process requiring interruption of the current working process. In I/O devices, one of the bus control lines is dedicated for this purpose and is called the Interrupt Service Routine (ISR).
