The computer was not discovered, it was invented. It was a long process of invention for the computer as we know it today.

First generation: (post World War II) Digital computers were enormous, developed mainly in the U.S. and used vacuum tubes.

Second generation: (around 1960) Computers then used transistors; these were the first successful commercial computers.

Third generation: (late 1960s and 1970s) These were characterized by using integrated circuits and miniaturizing components.

Fourth generation: (1974) The microprocessor chip defined these computers, which resemble our computers today.
