Hypertext Transfer Protocol provides a network protocol standard that web browsers and servers use to communicate. You see HTTP when you visit a website because the protocol is in the URL (for example, http://www.lifewire.com).

This protocol is similar to others, such as the file transfer protocol, in that it is used by a client program to request files from a remote server. In the case of HTTP, a web browser requests HTML files from a web server, which are then displayed in the browser along with text, images, hyperlinks, and related assets.
Tim Berners-Lee created the first HTTP standard in the early 1990s as part of his work defining the original World Wide Web. Three primary versions were deployed in the 1990s:
The latest version, HTTP 2.0, became an approved standard in 2015. This version is still compatible with HTTP 1.1, but offers additional performance improvements.
