A website (or Web site) is a collection of web pages, typically common to a particular domain name or subdomain on the World Wide Web on the Internet.

A web page is a document, typically written in HTML, that is almost always accessible via HTTP, a protocol that transfers information from the website's server to display in the user's web browser.

 

All publicly accessible websites are seen as constituting a mammoth "World Wide Web" of information.

 

The pages of a website will be accessed from a common root URL called 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 sites.
