In the 1600s, different calculating devices were built. Some of them were the Arithmetic Machine and the Step Reckoner. However, the Jacquard loom, a device created to simplify the production of textiles with complex patterns created by Joseph-Marie Jacquard, is considered to be the first information-processing device.

The Arithmometer was built by Charles Xavier Thomas de Colmar. As a result of the Industrial Revolution, calculation had to be mechanized. This device allowed addition, substraction, multiplication and division.

Colossus, a code-breaking machine, was created as part of a British project meant to develop technology to decode messages from the Germans during World War II. It was the first electronic digital computer.
-
It was a specific-purpose computer. It was created as part of a US project. It computed projectile trajectories and performed calculations for the atomic bomb. Then, in 1951, the UNIVAC appeared. It was the first commercial computer and it could be used for business and government applications.
-
This prototype was presented by Douglas Engelbart. It had a mouse and a graphical user interface. It could be used by the general public.
