-
Created by Konrad Zuse. A binary electrically driven mechanical calculator with limited programmability, reading instructions from punched celluloid film.
-
Created by John Vincent Atanasoff. For the purpose of testing two ideas central to his design: capacitors to store data in binary form and electronic logic circuits to perform addition and subtraction.
-
Created by Alan Turing. The first complete specification of an electronic stored-program all-purpose digital computer. Had Turing's ACE been built as he planned, it would have had vastly more memory than any of the other early computers, as well as being faster.
-
Created by William Shocky, Walter Brattian, and John Bardeen. A semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
-
Created by John McCarthy. Makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks.
-
Created by Jake Kilby, Masatoshi Shima, and Robert Noyce. A small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory.
-
Created by John Ambrose Fleming. A device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
-
Created by Douglas Engelbart, and Rene Sommer. A hand-held pointing device that detects two-dimensional motion relative to a surface.
-
Created by Marcian Hoff, Masatoshi Shima, Federico Faggin, and Stanley Mazor. A multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output.
-
Created by Tim Berners-Lee, and Robert Calliau. Connected the world in a way that was not possible before and made it much easier for people to get information, share and communicate.
-
Created by the top workers of Apple. Used to make and receive calls, watch movies, listen to music, browse the Web, and send and receive e-mail and text messages.

I feel that the First Programable Computer is the most important invention because it is the cause of the rest of the computer inventions
