Question

what is the meaning by interrupt,interrupt handler and interrupt table?

Answer 1

Interrupt mean a task by processor which change the regular task of processor.
Interrupt handler control's the Interrupt request and organized IR(Interrupt Request).
And Interrupt table store the Interrupt Request by their Priority.

Answer 2

An 'interrupt' is a request to the processor for accessing the system resources (for eg. memory) by any hardware device or software. It might be possible that when the request is dispatched by a device, the resource is already engaged in some other operation. In this case, the current operation should be paused or the interrupt be put on hold, is decided by the processor on the basis of priority of that interrupt, which is maintained in the 'interrupt table'. Further, when an interrupt is received, the execution of 'interrupt handler' is triggered, which are software routines. In other words, these routines define a set of predefined events which take place on the generation of interrupt.
