Why we say Centrally processing unit not controlling unit to C.P.U???

Why we say Centrally processing unit not controlling unit to C.P.U???

C.P.U: The full form of C.P.U is Central Processing Unit not Control Processing Unit although we all know that the C.P.U is the brain of the computer.This is where the computer does all its Processing work.It is very important hardware device. It controls all the working

but the Reason Behind Central Processing Unit is that:

computers works in three steps that is I.P.O.

1. input
2. processing
3. output

first we have to give input to the system to work upon then the system goes it in its 2nd stage that is processing which is done by C.P.U and after processing done by c.p.u it further forwarded to the monitor to display or we can say for output 

as monitor is an output device.
