trap 1. n. A program interrupt, usually an interrupt caused by some
   exceptional situation in the user program. In most cases, the OS
   performs some action, then returns control to the program. 2. vi. To
   cause a trap. "These instructions trap to the monitor." Also used
   transitively to indicate the cause of the trap. "The monitor traps all
   input/output instructions."

   This term is associated with assembler programming (`interrupt' or
   `exception' is more common among {HLL} programmers) and appears to be
   fading into history among programmers as the role of assembler continues
   to shrink. However, it is still important to computer architects and
   systems hackers (see {system}, sense 1), who use it to distinguish
   deterministically repeatable exceptions from timing-dependent ones (such
   as I/O interrupts).
