HTTP (an acronym for HyperText Transfer Protocol) is

a networking protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.[1]


HTTP is an Internet communications protocol for sending HyperText Markup Language (HTML) documents from one system to another and is the underlying protocol of the Web. By default, the Web server and client communicate on port 80.

The term "http" appears at the beginning of most Web addresses, and designates that the following alphanumeric character string is a Web address.

Because Web servers are linked to the Internet through a common communications protocol, known as hypertext transfer protocol ('HTTP'), a user can move seamlessly between documents, regardless of their location; when a user viewing a document located on one server selects a link to a document located elsewhere, the browser will automatically contact the second server and display the document.[2]
