摘要

"The CPU or central processing unit is basically a chip that plays the role of the brain of a computer. A microprocessor, on the other hand, is the circuitry which surrounds the CPU. Here, it must be noted that the microprocessor’s role in the functioning of a computer is much more than that of the CPU. It includes a series of other processing units such as graphics processing unit or GPU. Network cards and sound cards are also incorporated into the microprocessor. So, in short, it can be said that CPU is a major part of the microprocessor, but the microprocessor plays a much bigger role compared to the CPU. Read on to know more about the differences between microprocessor and CPU."

 

"Microprocessors receive electrical signals originating from various sources; these include network cards, memory, internal and external hard drives, video and graphics devices, input devices such as keyboard and mouse, etc. Here, it must be mentioned that currents from all the above-mentioned sources don’t reach the CPU. There are certain signals that are sent to different specialized chips. These are chips used as the CPU’s replacement and have dedicated microprocessors of their own. They are capable of processing their desired results independently. However, whatever might be the functions of other chips, the CPU plays the role of a coordinator in which all the processed signals get computed (these include even the signals coming from other chips)."
