Word Origin & History

trap  (n.)
late O.E. træppe "snare, trap," from P.Gmc. *trap- (cf. M.Du. trappe "trap, snare"), related to Gmc. words for "stair, step, tread" (cf. M.Du., M.L.G. trappe, treppe, Ger. Treppe "step, stair"). Probably connected to O.Fr. trape, Sp. trampa "trap, pit, snare," but the exact relationship is uncertain. The connecting notion seems to be "that on which an animal steps." Sense of "deceitful practice, trickery" is first recorded 1681. Sense in speed trap recorded from 1906. Slang meaning "mouth" is from 1776. The verb is attested from 1393 (O.E. had betræppan); trap door is first attested c.1374. Trapper "one who traps animals" (for fur, etc.) is recorded from 1768.

Computing Dictionary

trap
1. 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. 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).
