How Computer works?

Generally computer has four main sections the arithmetic logic unit (ALU), the control unit the memory, and the input devices and output devices. These parts are interconnected by busses, often made of groups of wires. The control unit, registers, ALU, and basic I/O are collectively known as CPU (central processing unit).
