A signal informing a program that an event has occured. When an interrupt is received the program stops normal execution and starts handling the interrupt by doing some special actions. There are two kinds of interrupts:

  1. Hardware: e.g. a user types something on a keyboard, the program has to process the input of the user and act apropriately
  2. Software: (also called an exception) e.g. when a program calls the operating system to do some disk I/O.
Internet Exploiter = I = interrupt list

interrupt

1. [techspeak] n. On a computer, an event that interrupts normal processing and temporarily diverts flow-of-control through an "interrupt handler" routine. See also trap. 2. interj. A request for attention from a hacker. Often explicitly spoken. "Interrupt -- have you seen Joe recently?" See priority interrupt. 3. Under MS-DOS, nearly synonymous with `system call', because the OS and BIOS routines are both called using the INT instruction (see interrupt list) and because programmers so often have to bypass the OS (going directly to a BIOS interrupt) to get reasonable performance.
