Programmable machine that can store, retrieve, and process data is a computer.It is derived from the Greek word "compute" which means to calculate but later on it has a vast nature not only limited on calculating.It consits of main memory, a control unit, and an arithmetic logic unit.Increasingly, personal computers contain specialized graphic processors, with dedicated memory, for handling the computations needed to display complex graphics, such as for three-dimensional simulations and games. Auxiliary data storage is usually provided by an internal hard disk and may be supplemented by other media such as floppy disks or CD-ROMs. Peripheral equipment includes input devices (e.g., keyboard, mouse) and output devices (e.g., monitor, printer), as well as the circuitry and cabling that connect all the components. Generations of computers are characterized by their technology. First-generation digital computers, developed mostly in the U.S. after World War II, used vacuum tubes and were enormous. The second generation, introduced c. 1960, used transistors and were the first successful commercial computers.

computer in modern life
The necessity of computer is increasing day by day due to its importance as it is useful in any field may in schols,colleges, offices, business, industries ,homes and so on.Simply, computer may be defined as a device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.URL: http://halloweenbox.com
