Harvard mark i and the bug
The next important effort towards devising an electromechanical computer was done at the harvard University, jointly sponsored by the Department of UN Navy and IBM, Howard Aiken of Harvard University developed a system called Mark I in 1944. Mark I was a decimal machine.
AS we have heard a term call "bug". It is mainly used to show errors in computer programs. This term was created, when one day, a program in Mark I did not run properly due to a short-circuit in computer. Since then, "bug" has been linked with errors and problems in computer programming. The process of eliminating error in a program is therefore, known as "debugging".
