- http stands for "Hyper Text Transfer Protocol", the primary technology protocol on the Web that allows linking and browsing.

For instance, you might log into your bank account on the Web. You will have to enter in a user name and password, and then after that you'll see your account info. Pay attention the next time you do this, and check the address bar at the top of your browser. It should indicate that you are now in a secure session with the addition of "https" at the front of the URL. For added security, always log out of any secure session when you're done, and especially if you are on a public computer.
