The Brains of the Computer
As I mentioned, the CPU is similar to the human brain. Every single operation that you do with your computer is processed in the CPU. The performance of your computer is based on simple mathematical operations, and the CPU is the device that controls all of those operations.
Let's say we are using a calculator to add two numbers. You enter the numbers using your keyboard. The keyboard controller turns all of that information into binary code. Binary code consists of sequences of 0 and 1. This information is then sent to the registry and then transferred to the CPU. The CPU has an integrated ALU (Arithmetical Logical Unit). The ALU is responsible for all mathematical and logical operations.
Your request to add two numbers comes to the CPU and is transferred to the ALU. The ALU adds the binary numbers and returns the answer to the CPU, which transfers the answer to an output device.
Adding two numbers is a very simple example, but it illustrates the basic functions of the CPU. Every single step you perform on your computer is in one way or another connected to this central unit, so it is very important to keep your processor in good form. Overheating, especially, can lead your CPU to fail.
