Hypertext Transfer Protocol (HTTP)

Hypertext Transfer Protocol, most commonly known as HTTP, is a protocol used in the World Wide Web that dictates which action web servers and browsers should take in response to different commands. For example, visiting any website sends a command to the web server and tells it to retrieve the relevant webpage and content. Clicking on to another page sends another request and retrieves the information again. Each of these requests are independent of each other. Here’s a video that does a good job explaining what HTTP is.
