I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

GET sends all the form data in the URL
POST sends all the form data in the request

A get sends a request for a specific resource e.g:

http://www.google.com 
This is a get request and will pull up the configured index page.
An HTTP response is returned usually a 200 (sometimes a 302 in the case of a redirect 404 if missing etc)

A post pushes data to the webserver
E.g. filling out a signup form at a website etc.

Though you can push data using both methods, GET generally will allow cached responses while post cannot be cached and will be returned from the server in each instance.
