An organization's presence or an individual's presence on the World Wide Web. A Web site is a collection of Web pages, which are documents coded in HTML that are linked to each other and very often to pages on other Web sites. A Web site is hosted on a server by its owner or by an Internet service provider (ISP). The site may share space on the server with other Web sites, reside on a server dedicated to that Web site only or be on multiple dedicated servers. To qualify as a bona fide Web site, the Web server must be available on the Internet 24 hours a day.
