All subscribers to the big online services like AOL and Compuserve have access to the World Wide Web. It is reasonable to suppose that the great majority of Internet users will use the World Wide Web. Information on the World Wide Web is provided by 'web sites'. The content of a web site is contained in a set of documents held as files on a 'host' computer. The host must be constantly connected to the Internet.
Every web site has a unique address, in effect a rather more user-friendly telephone number.
To access a web site you need to have appropriate World Wide Web software, Netscape is the market leader, and a connection to the Internet. Your Internet connection may be through an online service, like Compuserve, or through an Internet Service Provider, like Demon. The contents of a web site are displayed one document at a time. Users move from document to document by clicking on buttons. The basic function of a button is to request the loading of a new document.
