Control Unit (CU) : The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It tells the computer’s memory, arithmetic/logic unit and input and output devices how to respond to the instructions that have been sent to the processor.ALU (Arithmetic logic unit) : An arithmetic logic unit is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit, which operates on floating point numbers.
