Question

Describe common Functions of Interrupts?

Answer 1

Interrupt transfers control to the interrupt service routine normally, through the interrupt vector that has the addresses of all the service routines.

• A trap is a software-generated interrupt occurred either by an error or a user request.
• An operating system is interrupt driven.
