A central processing unit (CPU), also referred to as a central processor unit, is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The term has been in use in the computer industry at least since the early 1960s. The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same. The CPU is made of the Control Unit that controls the movement of data, the ALU (arithmetic logic unit) which performs logical operations and the Main Storage that allows data to be stored.
