The story of the "bug"
The term "bug" for errors in IT and software development actually predates the era of modern computers. The term "bug" was already used in the 1940s, when electronics and mechanics became increasingly important for military and scientific equipment.
Origin of the term "bug"
The first documented use of the term "bug" in connection with computers dates back to an incident in 1947. At that time, computer pioneer Grace Hopper's team was working on an early computer, the "Harvard Mark II". During their work, the team encountered an error in the system and discovered that a moth had been stuck in one of the computer's relays, causing a short circuit. This moth was then jokingly referred to as the first "real" computer bug, and the team even stuck the insect in their logbook with the note: "First actual case of bug being found."
Why the term is still modern
The story of the Moth became popular and the term "bug" became established in IT. It was used in engineering and later in software development in general to describe a fault or malfunction. Even before the Moth incident, the term was used in engineering and mechanics to describe small faults, but the famous incident made the term known among computer scientists worldwide.
Today, "bug" refers to any unexpected malfunction in software and hardware that can disrupt the normal operation of an application. The term has caught on because it is easy to understand and at the same time memorable.
