Interrupt


1. aka Hardware Interrupts: A request for attention from the processor. When the processor receives an interrupt, it suspends its current operations, saves the status of its work, and transfers control to a special routine known as an interrupt handler, which contains the instructions for dealing with the particular situation that caused the interrupt. ex: int 0x09 - keyboard interrupt 2. aka Software interrupts: functions stored in memory by the operating system to be used by programs to facilitate different tasks (aka system calls). ex: int 0x21 in MS-DOS
