How Computers Work: What is a CPU?
The CPU, or Central Processing Unit, is the brains of the computer. It is the most important component in the computer because it takes care of most of the millions of calculations the computer performs.
In personal computers, the CPU is a single chip called a microprocessor, and is a small, square chip with many little metallic pins sticking out of it that is inserted directly onto the motherboard. Modern CPUs also have a heat sink and small fan attached to keep them cool. CPUs do two major things: performing mathmatical and logical operations (in other words, making the computer do stuff), and retrieving and carrying out instructions from the computer's memory.
If something goes wrong with your CPU, it can be replaced but it's a good idea to let a professional do it. They can be expensive, and it's easy to accidentally bend the pins when trying to install it.
