MODERN COMPUTERS Modern computers are electronics and digital. The actual machinery is wires, transistor and circuits is called hardware, the instruction and data are called software. All general purpose computers require the following hardware components memory is enable a computers to store, at least temporarily, data and programs. Mass storage device is allows a computer to permanently retain large amounts of data. Common mass storage devices include dish drives and tape drives. Input device is usually a keyboard and mouse, the input device is the conduit through which data instruction enter computer. Output device is a display screen, printer other device that you see the computer has accomplished. Central processing unit (CPU) is the heart of the computer. This is a component that actually executes instructions. In addition to these components, many others make it possible for the basic components to work together efficiently. For example, every computer requires a bus that transmits data from one part of the computer to another.
