The full form of HTTP is the Hypertext Transfer Protocol. It is a kind of protocol which has been adopted by the World Wide Web’s rules and this protocol defines how data is formatted and transmitted. Also, HTTP directs how web browsers and servers should respond to a command. For example, when you input a web address in the browsing field of a web browser and press “Enter”, an HTTP command is sent to a server. That command asks the server to send data to your browser for that website.
