Answer Posted / meenakshi garg
interrupt is a process when the an external device can use
the micro-processor. it is an asynchronous signal which can
be hardware or software and it is considered as an
emergency signal.Whenever the microprocessor receives an
interrupt signal,it stops the execution of current program
and jumps into the interrupt service routine(ISR).After
finishing the higher priority task it return back to normal
execution.
