HyperText Transfer Protocol
 

When the World Wide Web was created, one of the new features it provided was a new Internet Protocol for managing hypertext information across the Internet: HTTP, or HyperText Transfer Protocol. HTTP is a simple protocol that allows for the hypertext documents to be transferred quickly over the Net between Web browsers and servers. Unless you are writing your own server, or are overly curious about the innards of the Web, you won't really need to know much more about HTP than what it's there for.
