Http
Hypertext transfer protocol - the familiar http:// in your address box, is the system that regulates the way computers talk to each other and transmit data across the Internet - the very same system that allows you to surf the Web, moving from site to site and page to page. When you type in an address or click on a link, you're instructing the computer hosting those details to send it to you. (Also see Hypertext and Hyperlink)
