The First Computer Bug Was an Insect - Apparently.
In 1947, a team of engineers working on the Harvard Mark II computer found a moth stuck in one of the relay switches, causing the machine to malfunction. The team taped the moth to the computer log with the note "First actual case of bug being found." This incident marked the first recorded instance of the term "bug" being used to describe a technical error. The moth is now preserved at the Smithsonian Institution, serving as a quirky piece of computer history.
