A functional unit of a computer refers to a component or module that performs a specific task or carries out a particular function within a computer system. Some examples of functional units in a computer include the central processing unit (CPU), memory unit, input/output (I/O) unit, arithmetic logic unit (ALU), control unit, and cache memory. These units work together to enable the computer to execute operations, store and retrieve data, process information, and interact with the user and peripheral devices.
