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.
