 BUG [from telephone terminology, "bugs in a telephone
       cable", blamed for noisy lines; however, Jean Sammet has
       repeatedly been heard to claim that the use of the term in CS comes
       from a story concerning actual bugs found wedged in an early
       malfunctioning computer] n. An unwanted and unintended property of a
       program. (People can have bugs too (even winners) as in "PHW is a
       super winner, but he has some bugs.") See FEATURE.
