Document Summary
A cpu functions more like a very powerful calculator than like a brain. Today, cpus add, subtract, multiply, divide and move billions of numbers per second. It"s the speed of the cpu that enables computers to perform feats such as accessing the internet, playing visually stunning games, or editing photos. To understand how a cpu works, it"s best to visualize it as a man in a box. The man in the box can perform virtually any mathematical function, manipulate data, and give answers very quickly. This guy is very useful, but there"s a catch- he lives closed up in a tiny box. You have to figure out a way to exchange information with him in order for him to work with you. 8 light bulbs are placed on the inside of the box, and 8 light bulbs are placed on the outside of the box.
