After working on his revolutionary difference engine , designed to aid in navigational calculations, in he realized that a much more general design, an Analytical Engine , was possible.

The input of programs and data was to be provided to the machine via punched cards , a method being used at the time to direct mechanical looms such as the Jacquard loom. For output, the machine would have a printer, a curve plotter and a bell. The machine would also be able to punch numbers onto cards to be read in later. The Engine incorporated an arithmetic logic unit , control flow in the form of conditional branching and loops , and integrated memory , making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete.

Eventually, the project was dissolved with the decision of the British Government to cease funding.

Basic Computer Terms

Babbage's failure to complete the analytical engine can be chiefly attributed to political and financial difficulties as well as his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage, completed a simplified version of the analytical engine's computing unit the mill in He gave a successful demonstration of its use in computing tables in Analog computers Sir William Thomson 's third tide-predicting machine design, —81 During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers , which used a direct mechanical or electrical model of the problem as a basis for computation.

However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers. The differential analyser , a mechanical analog computer designed to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized in by James Thomson , the brother of the more famous Lord Kelvin. This built on the mechanical integrators of James Thomson and the torque amplifiers invented by H. A dozen of these devices were built before their obsolescence became obvious.

By the s, the success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remained in use during the s in some specialized applications such as education control systems and aircraft slide rule.

Digital computers It has been suggested that this section be split out into another article titled Digital computer. Discuss May Electromechanical By , the United States Navy had developed an electromechanical analog computer small enough to use aboard a submarine.

This was the Torpedo Data Computer , which used trigonometry to solve the problem of firing a torpedo at a moving target. During World War II similar devices were developed in other countries as well. Replica of Zuse 's Z3 , the first fully automatic, digital electromechanical computer.

Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2 , created by German engineer Konrad Zuse in , was one of the earliest examples of an electromechanical relay computer.

It was quite similar to modern machines in some respects, pioneering numerous advances such as floating point numbers. Rather than the harder-to-implement decimal system used in Charles Babbage 's earlier design , using a binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time.

The engineer Tommy Flowers , working at the Post Office Research Station in London in the s, began to explore the possible use of electronics for the telephone exchange. Experimental equipment that he built in went into operation five years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes.

The German encryption machine, Enigma , was first attacked with the help of the electro-mechanical bombes which were often run by women. 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 contained 1, thermionic valves tubes , but 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 the 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. On the left hand side of the window you will see common folders and drives on your system. You can navigate directly to each of these places by clicking on them.
