Computer’s History

Computer is true newly sounded so scream at this last several years, exactly at mid-20th century ( around 1940 – 1945 ), but do you know that the prototype of computer ( computing device ) already started for centuries ago.

According to the history, the first device to computing is made by Chinese, the name of the device is Abacus (which dates from about 150-100 BC), and than after that many devices are pop out.

The end of the middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Scihkard'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.

At industrial revolution in 19th centuries, start to be recognize two factory tools system (1812), machine that operated by human and by a machine language.

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



After long process, the first generation computer was made in 1942. At this generation computer is really huge, his weight until 30 ton. Its caused by the primary component at this computer is vacuum tube ( electronic vacuum tubes ). Example of this generation is ENIAC ( electronic numerical integrator and calculator ).

The second generation of computer is pop out in 1959. At the second generation, transistor and magnetic core storage were begin used. Computer at this generation is not common heat than generation before. Some examples of this generation are IBM series 1400, 1401, 1600, and series 7070-7090.

At the third generation, the primary component that was used is Integrated Circuit ( IC ).
Inside this IC there is millions transistors that compacted, the example is IBM S/370.

Along with the growth of epoch, start at 1971, the computer scientist was began compacted millions of IC that we call Microprocessor. This computer is the fourth generation.

Now some people said that we already entered in the fifth generation, because in the modern computer now there is new components.
