Where did the name computer bug come from?

Answer 1

that someone found a mouth on the fan and thts where they got the name from

The term "bug" had been in use for any malfunction or error of a machine long before electronic digital computers existed.

Its first use referring to a computer problem was on the Harvard Mark II electromechanical computer, when a moth got smashed inside the contacts of a relay causing a failure. When the failure was located and the moth removed from the relay, the operator on that shift taped it to the logbook below the entry on the failure and labeled it First Computer Bug. That morning Grace Murray Hopper came on duty and read the logbook and thought it was a great story to tell every time she spoke somewhere. The first computer bug wasn't even in an electronic computer, the Harvard Mark II was electromechanical & it was not a softwareproblem but a hardware problem.

Answer 2

the very first computer problem left IT technicians baffled. when they opened up the machine, they found a dead insect and determined that it was causing the problem. from then all computer problems and inconsistencies are called bugs.
