First Programmable Computer
German engineer Konrad Zeus was the inventor of the world's first binary programmable computer. This computer could read instructions from punched tape and make decisions from boolean logic relays. -
The Programmable Calculator
This calculator was invented by Howard Aiken and his colleagues at Harvard. The machine had: 1-million parts, over 500 miles of wiring, and weighed 5 tons. This calculator could solve math problems in just a couple seconds. -
First Digital Computer
This computer was invented by John Atanasoff and his graduate student Clifford Berry. It could solve 29 equations at a time. To do this, it used vacuum tubes and boolean logic. -
Electrical Numerical Integrator and Computer
The ENIAC had almost 18,000 vacuum tubes and filled up an entire room. It was completed by John Mauchly. This machine was the first successful digital computer to run at such a high speeds. -
Electronic Discrete Variable Automatic Computer
The EDVAC was invented by John Presper Eckert. The significance of this computer was that it was the first stored programmed computer. The EDVAC was able to operate over 1,00 instructions per second. The modern revolution of computing was made possible after this invention.
