These parts are interconnected by buses, often made of groups of wires.Inside each of these parts are trillions of small electrical circuits which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a “1”, and when off it represents a “0” (in positive logic representation). The Circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits.The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CUPs have typically been constructed on a single integrated circuit called a microprocessor.The control unit (often called a control system or central controller) manages the computer’s various components; it reads and interprets, (decodes) the program instructions, transforming them into a series of control signals which activate other parts of the computer. Control systems in advanced computers may change the order of some instructions so as to improve performance.
