Bug - в переводе с английского "жук"
НО ! Среди компьютерщиков есть несколько трактований :
bug
(баг) нелогичное или непоследовательное поведение программы в особых случаях, или поведение, которое не следует из документации или принятых для программы стандартов. Часто бывает, что новые возможности вносят новые баги в программы. Исторически, этот термин появился во времена перфокарт: баг (реальный жук!) отдыхал в дырке перфокарты, и из-за него программа не работала. Адмирал Grace Hopper, который это обнаружил, воскликнул “It's a bug!” (это жук!), и с тех пор это так и осталось в терминологии. Имейте в виду, что это только одна из многих историй, объясняющих причину появления термина bug.

А вот тут намекают на боее раннее появления слова bug, как ошибка :
Bug
Popular etymology (or perhaps it is entomology in this case) has it that Grace Hopper, naval officer and computer pioneer, coined the term bug for a computer defect when she discovered an insect in a malfunctioning computer. It's a fun story, and it's even true, except in that it is not the origin of the term. Hopper (or perhaps one of her colleagues) did discover an insect in a computer, but the term bug for 'defect' dates from the nineteenth century.
In 1947, computer workers on the Harvard Mark II machine at the Naval Surface Warfare Center in Dahlgren, Virginia found a moth in a relay of the machine. They taped the insect into their logbook and recorded it as the "first actual case of bug being found." This was clearly a case of the workers making a joke. Lots of bugs (i.e., defects) had been found, but this was the first "actual" bug (i.e., insect). The log book is now at the Smithsonian's Museum of American History. Grace Hopper came to be associated with the story as she was a programmer for the Mark II and often told the story.
This was not the first use of bug to mean defect. That usage was quite common by 1947. The earliest references to the usage in the
OED2 and the
Random House Historical Dictionary of American Slang refer to Thomas Edison, and the term may have been coined by him or someone in his laboratory. The earliest usage cite dates from 1878 (Random House).
