The World Wide Web is one of the greatest inventions we've seen in the last few years. However, it suffers from some limitations.
Web pages are basically billboards that people can read.
A company by the name of Sun Microcomputers realized there was a need for more interactivity, so they created a computer language called Java. Java runs on any computer, from Macs to PCs to mainframes without any changes. It also has built in security measures to prevent the creation of Java viruses. You'll start to see quite a few references to Java in the near future. Even though Java started out as an add-in to the Internet, it has grown into its own Operating System.
