who invented computer?

Answer 1

It is difficult to define any one device as the earliest computer. The very definition of a computer has changed and it is therefore impossible to identify the first computer. Many devices once called "computers" would no longer qualify as such by today's standards.

Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating device. Examples of early mechanical computing devices included the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC). The end of the Middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers.

However, none of those devices fit the modern definition of a computer because they could not be programmed. In 1801, Joseph Marie Jacquard made an improvement to the textile loom that used a series of punched paper cards as a template to allow his loom to weave intricate patterns automatically. The resulting Jacquard loom was an important step in the development of computers because the use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of programmability.

In 1837, Charles Babbage was the first to conceptualize and design a fully programmable mechanical computer that he called "The Analytical Engine".[2] Due to limited finance, and an inability to resist tinkering with the design, Babbage never actually built his Analytical Engine.

Large-scale automated data processing of punched cards was performed for the US Census in 1890 by tabulating machines designed by Herman Hollerith and manufactured by the Computing Tabulating Recording Corporation, which later became IBM. By the end of the 19th century a number of technologies that would later prove useful in the realization of practical computers had begun to appear: the punched card, boolean algebra, the vacuum tube (thermionic valve) and the teleprinter.

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.

Answer 2

There were some electronic computers with very limited capabilities built just before WW2 though they would probably be more like calculators in todays language.

The closest thing to a modern electronic computer after that was "Colossus", largely designed by Tommy Flowers using ideas from Alan Turing. It was built at Bletchley Park in England to decipher the German Enigma signal traffic, particularly the more complex Naval Enigma.

The machine was carefully destroyed right after WW2 as it was thought that if it's success were revealed a potential enemy would devise an even more complex cipher. This had happened after WW1 since the British had revealed they had broken much of the German ciphers in 1914 -1918 and this had resulted in Enigma.

A few years later the American produced a similar machine called Univac.

The existence of Colossus and the breaking of Enigma was not revealed until 1975, 30 years after the war.

Early digital computers were actually simpler in most respects than automatic telephone exchanges.

Answer 3

If you say somputer in the sense like an mechanized calculator then its Wilhelm Schickard, you mean a programmable computer then its Charles Babbage.
