The full form of CPU is the Central processing unit commonly called processor in computers. But many people confuse the work CPU with the entire computer box in which all the other essential hardware is installed. To locate a processor in most devices, just find a fan attached to cool something on a motherboard. And that “something” is our CPU or processor. Since the processor generates heat during the computing tasks, that’s why the fan is installed to cool it down a bit for better performance and efficiency.
For those who are just learning about computers, the CPU is a processing unit that computes input data after receiving instructions from programs or apps that are already installed on the system. This entire computing process happens in three parts: first, the CPU loads up data from RAM, then decodes the instructions, and then executes the results in the form that can be printed on the screen. Since every form of data is binary at its core, you can think of the CPU as something that processes that binary data and makes sense of it visually (most of the time).
