What are interrupts? 

Interrupt: An interrupt is a hardware mechanism which enables an external device, classically input/output devices, to send a signal to the CPU. An interrupt signal requests the CPU to interrupt its present activities and attend to the interrupting devices requires. A CPU  will  check  interrupts  only  after  this  has  done  the  processing  of  one instruction  and before this fetches a subsequent one.
