Hypertext Transfer Protocol

What Is HTTP?

If you have a nifty document markup language (HTML), that can contain links ("HyperText") to other documents (using URL's) anywhere on the fantastic inter-connected network of computers (aka the "Internet") then you need a protocol (a standard way to communicate) for transferring your HTML documents.

So, HTTP is a "Tranfer Protocol" for sending "HyperText Markup" documents (and other documents) across the internet. That's it!

HTTP is a clear text protocol. That means that any information sent via HTTP can be understood by any device that listens to the traffic on the internet.

HTTPS

There is also the secure version (HTTPS) that starts with a nice secure socket layer (SSL) and then sends files using the same standard of HTTP through the secure socket. (Think of "HTTPS" as "HTTP over SSL").
