The Brief History Of Computer

The computer as we know it today had its beginning with a 19 the century English mathematics professor named Charles Babbage.
He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.

Generally speaking, computers can be grouped into three generations. Each generation lasted for a certain period of
time and each gave us either a brand-new and improved computer or further improvements to the existing computer.

First generation: 1937 - 1946- In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was "ve called the" Atanasoff-Berry Computer( ABC ). In 1943 an electronic computer name the Colossus was built for the military. Other progress persisted until in 1946 the first general- intent digital computer, the Electronic Numerical Integrator and Computer( ENIAC) was built. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes that were used for processing. When this computer was turned on for the first time lightings dim in segments of Philadelphia. Computers of this generation could only perform a single task, and they had no operating system.

Second generation: 1947 - 1962- This generation of computers applied transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for commercial employ was introduced to the public; the Universal Automatic Computer( UNIVAC 1 ). In 1953 the International Business Machine( IBM) 650 and 700 series computers attained their score in the computer world. During this generation of computers over 100 computer programming languages were put forward, computers had remembrance and operating systems. Storage media such as tape and disk were in use also were printers for output.

Third generation: 1963- present- The invention of the integrated circuit brought us the third generation of computers. With these invention computers became smaller, more powerful more reliable and they can run many different programs at the same time. In1980 Microsoft Disk Operating System( MS-Dos) was born and in 1981 IBM introduced the personal computer( PC) for home and bureau use. Three years later Apple gave us the Macintosh computer with its icon-driven interface and the 90 s gave us Windows operating system.

As a result of the various improvements to the development of the computer, we have seen the computer being used in all areas of life. It is a very useful tool that will continue to experience new development as period passes.
