Computers are tools used to process the data according to the procedures that have been formulated.
Computer word originally used to describe the work people do arithmetic calculations, with or without tools, but the meaning of this word and then transferred to the machine itself. Their origins, processing information almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.
Broadly speaking, the
computer can be defined as an electronic device that consists of several components, which can work together between the components with one another to produce a program based on information and data. The computer components are included: Screen Monitor, CPU, Keyboard, Mouse and Printer (as a complement). Without a computer printer can still perform his job as a data processor, but the extent not yet seen on the screen monitor in the form of print (paper).
In such a definition is a tool like a slide rule, mechanical calculator types ranging from abacus, and so on, until all contemporary electronic computers. Better terms suitable for a broad sense such as "computer" is "that process information" or "information-processing system."
Currently, computers are increasingly sophisticated. However, before the computer is not small, sophisticated, cool and light as now. In the history of computers, there are 5 generations of computer history.
1. First generation (1944-1959)
Electronic computers of the world's first ENIAC was completed. On the computer there are 18,800 vacuum tubes and weighs 30 tons. so large in size, to the point of requiring a separate classroom.
2. Second Generation (1960-1964)
In the 1960s, IBM introduced the use of commercial computer to use transistors and began circulating widely in the market. IBM-7090 computer made in the United States is one that uses a commercial computer transistors.
3. Third Generation (1964-1975)
The concept of smaller and more affordable than transistors, eventually spur people to continue to conduct various studies. Thousands transistor finally combined in one form a very small. Yag silicium piece has managed to measure a few millimeters is created, and this is what is called the integrated circuit or IC-chip that is characteristic of third generation computers.
4. Fourth Generation (1975-Present)
Is a typical microprocessor computer chiri fourth generation which is compacting into a thousand IC Chip. Because of the smaller and the increasing capabilities and prices offered are also more affordable. Microprocessor is the beginning of the birth of personal computers.
5. Fifth Generation (Present - Future)
In this generation is marked by the rise: LSI (Large Scale Integration), which is a compression of thousands of microprocessors into a microprocesor. There was also marked by the emergence of microprocessor and semi-conductors. Companies that make micro-processor.
