The name **"computer"** was used to refer a person that used a calculator in 1613. Years after, a person said it will be a name of a thing that can carrier many **calculators** or computations, that was a other name of this same thing and that can be **programmed**. In 80 b.C. the Greeks made a kind of computer, because it can alculate things. In 1623 Europeans engeneers made mechanics calculators, but they wheren't computers, because they couldn't be programmed! In 1936 **Alan Turic** did one computer that concept the algorithm and computation with the Turing machine provading a blueprint for the eletronic digital computer. Because of that, the //Time// magazine in naming Turing one of the most 100 influential people of 20th century, states: "The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working on an incarnation of a Turing machine" . Other person that was very important to this new computers exist was **Konrad Zuse**, because he created the program-controlled computer and the first work computer in 1941 and other in 1955 that was the first computer based on magnetic storage. Several developers of ENIAC, came out with more flexible and elegant design, that after be know as "stored program architecture". The design was created by **John von Neumann.** In 1950s two Soviet scientists created the **binary nubering** that is the sistem that many computers are based! This sistem represents values using 1 and 0.
