Parts of Computer

 

   

    A general purpose computer has four main components: the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by busses, often made of groups of wires.


    The control unit, ALU, registers, and basic I/O are collectively known as a central processing unit (CPU).
