A Web site is a group of HTML pages and graphics that are interconnected with hyperlinks. A typical example of a Web site is shown here.
Actually, this is the simplest form of a Web site. Web sites can also contain word processor documents, multimedia, scripts, and databases—any kind of file. They can even have other Web sites, called subsites, that are nested within.
