Programmable machine that can store, retrieve, and process data.
Today's computers have at least one CPU that performs most calculations and includes a main memory, a control unit, and an arithmetic logic unit. Increasingly, hard disk and may be supplemented by other media such as floppy disk s or CD-ROM s. 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 computer s, developed mostly in the U.S. after World War II, used vacuum tube s and were enormous. The second generation, introduced с 1960, used transistor s and were the first successful commercial computers. Third-generation computers (late 1960s and 1970s) were characterized by miniaturization of components and use of integrated circuit s. The microprocessor chip, introduced in 1974, defines fourth-generation computers.
