HTTP is short for “Hypertext Transfer Protocol” in English, an underlying protocol used by the World Wide Web. HTTP defines how messages are formed and transmitted and what actions web servers and browsers should take in response to various commands.
Examples of http
For example, when a URL is entered into the browser, the browser sends an HTTP command to the web server directing it to search and transmit the requested web page. The other main rule that controls the operation of the World Wide Web is HTML, which deals with how web pages are formatted and displayed.
