Have you ever encountered a computer bug? How about a real bug in your computer? In 1947 a technician at Harvard had an issue with the performance of their Mark II computer.

- Once they investigated, they discovered that a moth had gotten into a relay – an actual real live bug. In the logbook, it was noted as “First actual case of bug being found.”
|

- While it is oft-repeated that this is where the term “bug” came to refer to errors that impacted the performance of programs, this is not the case.
|
|
|
- The term “bug” was already in fairly widespread use in technical circles in 1947. Thomas Edison used it in 1869 to describe problems in his own inventions.
