Difference between CPU and Microprocessor

After readed this article and given responce, the problem was occured that have GPU same features like CPU ?

Answer 1

I would say that microprocessor is a more general term for any silicon that is capable of processing. By CPU you're referring to the (or one of the) main processing modules within a system. So for, example, a GPU or a DAC are both microprocessors, but not CPUs.
