The central processing unit (cpu) is the computer component that's responsible for interpreting and executing most of the commands from the computer's other hardware and software. A central processing unit (cpu), or sometimes just called processor, is a description of a class of logic machines that can execute computer programs this broad definition can easily be applied to many early computers that existed long before the term cpu ever came into widespread usage.
