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.
