As early as the seventeenth century,
mathematicians were trying to create a machine that could perform basic mathematical functions such as, addition, subtraction, division and multiplication.
1804 British inventor, Charles Babbage, designed an all-purpose problem-solving machine, the difference engine, which had a mechanical memory to store the results of calculations .
Generation of ComputerFirst Generation
1940-1956 : Vacuum
Tubes The first computers used vacuum tubes for circuitry and magnet i c dr ums for
memor y, and were often
enormous, taking up entire rooms .
The UNIVAC and ENIAC
computers are first-generation computing devices .
Second Generation - 1956-1963 : Transistors
Transistors replaced vacuum tubes an
d ushered in the second ge neration of computers. The
transistor was invented in1947 but did not se
e widespread use in compu ters until the late 50s.
* smaller,faster and cheaper.
Third Generation - 1964-1971 : Integrated Circuits The development of the
integrated circuit was the
hallmark of the third generation of computers .Transistors were miniaturized and placed on silicon chips,
called semiconductors, which
drastically increased the speed and efficiency of computers. First Integrated Circuit
Fourth Generation - 1971-Present : Microprocessors The microprocessor
brought the fourth generation of computers, as thousands of integrated circuits were built onto a
single silicon chip.
Fifth Generation of Computer
Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications , such a
s voice recognition , that are b
eing used today.
