Like the trap, the interrupt stops the running program and transfers control to an interrupt handler, which performs some appropriate action. When finished, the interrupt handler returns control to the interrupted program.
The concept of an interrupt is something that has expanded in scope over the years. The 80x86 family has only added to the confusion surrounding interrupts by introducing the int (software interrupt) instruction. Indeed, different manufacturers have used terms like exceptions, faults, aborts, traps and interrupts to describe the phenomena this chapter discusses. Unfortunately there is no clear consensus as to the exact meaning of these terms. Different authors adopt different terms to their own use.
