These are two different METHODs (<form METHOD=""> ) to send data to a CGI
by means of the webserver and HTTP.

GET is just adding the parameters after a question mark to the url in form
variablename=value. variables are separated with &, which you should code
as &amp; when you use it in links like <a href="xxx?vara=1&amp;varb=2">.
CGIs parse these variables and their values out of environment variable
QUERY_STRING.

POST sends the data after the request headers. CGIs read from stdin to read
the same. POST isn't limited and can send MIME conform.

GET is limited to 4KB with the Original HTTP Server and to 8KB on Apache.

That's, a bit simplified, the whole thing.

If you are really interested, you can dive deeper by examining HTTP
conversations with a tool like JunkBuster's Proxy
http://www.junkbusters.org/ and reading RFCs.
