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.
