Functional Units of Computer Every functional system incorporates some functional parts that constitute a consumable product. Similarly, there are some functional units of the computer that constitute in producing logical outputs. The five basic functional units of a computer are: Input unit, Aprocessing unit (Arithmetic and logic) Amemory to store final or intermediate results A controlling unit that coordinates functions of every unit, and An output unit In this post, we will discuss all the functional units of the computer. Functional Unit of Computer The functional units of a computer, i.e. input unit, arithmetic and logic unit, memory, control unit, and output unit, all are connected to the interconnection network that helps them in exchanging information, as you can see in the image below. Now, let us explore each functional unit separately. Input Unit : The input to the computer is either data ...
