However, most of my information was in books. The thing that was not helpful was that the school library had no books on my topic. A video game system is a small computer that displays games on your television set. Stores sell more than a dozen different systems of varying power. The more power a video game system has the more powerful it is.
Some systems use compact discs, which hold more information than cartridges.
CD's allow programmers to pack more action and graphics. Some systems have 16 bits and some have 64. The design and cleverness of the actual games available for a system are probably more important that a systems raw power. To compete with CD games, like Playstation. Nintendo is putting more powerful computer chips into cartridges.
