It is a very essential part of the cpu.
The set of instruction is in the form of raw data. The alu arithmetic logic unit is the part of a cpu that actually does calculations and condition testing. In other words each of these devices acts as a mediator. The most basic arithmetic operation is the addition of two binary digits.
