History of Computers: A Brief Timeline
Experimental equipment that he built in went into operation five years later, converting a portion of the telephone exchange history of computer into an electronic data processing system, using thousands of vacuum tubes. The German encryption machine, Enigmawas first attacked with the help of the electro-mechanical bombes.
It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it was not Turing-complete. Colossus Mark I history of computer 1, thermionic valves tubesbut Mark II with 2, valves, was both 5 times faster and simpler to operate than Mark I, greatly speeding the decoding process.

Like the Colossus, a "program" on the ENIAC was defined by the states of its patch cables and switches, a far cry from history of computer stored program electronic machines that came later.
Once a program was written, it had to be mechanically set into the machine with manual resetting of plugs and switches. It combined the high speed of electronics with the ability to be programmed for many complex problems.

It could add or subtract times a second, a thousand times faster than any other machine. It also had modules to multiply, divide, and square root. High speed memory history of computer limited to 20 words about 80 bytes.
Built under the direction of John Mauchly and J.
History of Computers
The machine was huge, weighing 30 tons, using history of computer of electric power and contained over 18, vacuum tubes, 1, relays, and hundreds of thousands of resistors, capacitors, and inductors.
Turing proposed a simple device that he called "Universal Computing machine" and that is now known as a universal Turing machine.
He proved that such a machine is capable of computing anything that is computable by executing instructions program stored on tape, allowing the machine to be programmable.
The fundamental concept of Turing's design is the stored history of computerwhere all the instructions for computing are stored in memory. In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs.
Early computers would use similar punch cards.
English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. The project, funded by history of computer English government, is a failure.
More than a century later, however, the world's first computer was actually built. He establishes a company that would ultimately become IBM.
Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of history of computer anything that is computable.
The central concept of the modern computer was based on his ideas. Atanasoff, a professor of physics and mathematics at Iowa State University, attempts to build the first computer without gears, cams, belts or shafts.
Atanasoff and his graduate student, Clifford Berry, design a computer that can solve 29 equations simultaneously.

This marks the first time a computer is able to store information on its main memory. They had to history of computer all the heady problems of developing such a device, of implementing the design, of actually building the thing.
The history of the solving of history of computer problems is the history of the computer. That history is covered in this section, and links are provided to entries on many of the individuals and companies mentioned. In addition, see the articles computer science and supercomputer.
