Did they have computers in 1940?

In the 1940s, computers took up entire rooms, like the ENIAC, which was once called a “mathematical robot.” John Mauchly created the ENIAC during World War II to help the Army with ballistics analytics. The machine could calculate thousands of problems each second.

What were computers like in the 1940s?

The computers in the 1940s and 1950s were mostly based on vacuum tubes. Transistors showed up late in the game, and integrated circuits were just a distant dream and didn’t start showing up in computers until the 1960s, and then in very limited capacity.
