2. binary circuits First binary circuit invented by: Georges Stibitz in 1937 All computers rely on a binary system of ones and zeros to determine its rules of logic. Used in Cd’s to read the data off of them.

3. Electric Typewriter IBM invented the electric typewriter in 1935 This device was exclusively electric, one of its main draws was the elimination of time consuming tasks and elimination of fatigue with the new light touch keys. First all electric typewriters First to use a typebar mechanism

4. The Turing Machine 1936 - Alan Turing writes a paper describing a theoretical computer that was a simple information processor - but it was brilliant! Reads symbols on a strip of tape and follows the directions on the strip of tape according to the symbols on the tape. its very smart Developed a language called Turing Complete for the machine

5. Speech Synthesizer Machine 1936 - Bell Labs invents a working speech synthesizer Used a keyboard and pedals to control and emit sounds User types in words and when pedal is pressed the machine speaks it. Concept still used today for speech disabled persons

6. Differential Analyzer This device was invented by Vannevar Bush in 1930. This device was used to compute complex equations. This was basically a large scale more complicated calculator. Composed of integrators which computed the data.

7. Konrad Zuse Konrad Zuse was a German civil engineer who invented the first ever program controlled computer called the Z1.
