eli5: What is bandwidth?
In: 48
When you look at a rainbow and pick out colors you can look at a tiny sliver of yellow or a big patch of orange stretching from red to yellow. The “width” of that “band” is the bandwitth. Because more types of colors are in it you can signal more information. With a tiny slice you can only signal dark or light, but with more color you can add a little more red or a little more blue or darker or lighter. The amount of information you can send is determined by if you can tell the difference between them.
