HTML and HTTP

HTML: Stands for HyperText Markup Language

HTML is what browsers understand. HTML tells a browser how to display things on a screen.

Question: How do we get to a web page?

You type a website's name into the address bar at the top of your browser.

A website's name usually has www in it, which stands for World Wide Web.

Websites usually end in .com or .org or .gov

Those are called "domains". Every web address has a domain.

Another name for a website address is URL.

URL stands for Uniform Resource Locator.

URLs usually start with http://

What's that?

HTTP stands for HyperText Transfer Protocol

HTTP is just the way that computers ask for information from each other and reply to each other.

HyperText is text that links to other text.

Every URL has a part that says what protocol it is using
