A website, Web site or WWW site (often shortened to just site) is a collection of Web pages, that is, HTML/XHTML documents accessible generally via HTTP on the Internet; all publicly accessible websites in existence comprise the World Wide Web.

The pages of a website will be accessed from a common root URL, the homepage, and usually reside on the same physical server.

The URLs of the pages organize them into a hierarchy, although the hyperlinks between them control how the reader perceives the overall structure and how the traffic flows between the different parts of the site. *
