All beer is created with yeast, but there are filtration processes that can remove yeast from the final product. All domestic beer in the United States such as Budweiser is yeast-free by law.
There are three main reasons for racking. Firstly, if you wish to ferment your beer longer than say 10 days, moving the beer off the yeast cake will reduce the risk of autolysis, a process whereby yeast cells, having consumed all other available food, begin to metabolise each other, creating a foul taste.
