A CPU, or Central Processing Unit, is the brain of a computer. It is the part of the computer that makes the computer work. Think of it like the boss that tells the other parts of the computer what to do.
To make a CPU, you first need a factory with special machines that can make very small and precise parts. Then, you put all of the tiny parts together in a special way to make the CPU. Once it is built, you test it to make sure it works properly.
Finally, you put the CPU into a computer, plug it in, and turn it on. Now the computer can do things like play games, search the internet, and write letters.
