What is a computer processing device?

A computer processing device is the part of the computer that receives input, processes the input and gives output. In most computers, the central processing unit is the computer processing device.

Computers take in information, process that information with code and give results. The computer processing device, or CPU, is where information is processed. The CPU is similar to the brain in a person. It receives information that is input by users or from external sensors, it decides what to do with that information based on the code programmed into it, and then it gives output to the user. The CPU connects to the motherboard, which gives it access to all the other components of a modern computing system.
