What is a computer? Computer is an electronic device that stores, retrieves and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Information in the form of data and programs is known as software, and the electronic and mechanical parts that make up a computer system are called hardware. A standard computer system consists of three main sections: the central processing unit, the main memory, and the peripherals. Perhaps the most influential component is the central processing unit. Its function is to execute program instructions and coordinate the activities of all the other units. In a way it is the "brain" of the computer. The main memory holds the instructions and data which are currently being processed by the CPU. The peripherals are physical units attached to the computer. They include storage devices and input/output devices. Storage devices (floppy, hard, optical disks) provide a permanent storage of both data and programs. Disk drives are used to handle one or more floppy disks. Input devices enable data to go into the computer's memory. The most common input devices are the mouse and the keyboard. Output devices enable us to extract the finished product from the system. These are the main physical units of a computer system, generally known as the configuration. 1...A computer is composed of only hardware. 2.A3Tondonda standard computer system consists of the central processing unit, the main memory, and the peripherals. 3.
