1. The Internet standard that supports the exchange of information on the World Wide Web (WWW). By defining Universal Resource Locators (URLs) and how they can be used to retrieve resources (including not only Web documents but also File Transport Protocol (FTP)-accessible files, Usenet newsgroups, and Gopher menus) anywhere on the Internet, HTTP enables Web authors to embed hyperlinks in Web documents. When clicked, a hyperlink initiates a data transfer process that accesses and retrieves document, without any further intervention from the use (or, indeed, without any knowledge of where the document is coming from or how it was accessed). In short, HTTP lays the foundation for transparent access to the Internet. From QUECID

2. The protocol used to provide hypertext links between pages. It is the standard way of transfering HTML documents between Web servers and browsers. From Glossary of Distance Education and Internet Terminology
