as noted by the_coder: "You probably mean get and post. Get uses the URL to send the information to the server, while Post places it in the HTTP message body. That's probably a sufficient answer for a recruiter. If you're talking to an engineer, he'll probably ask when you'd use one over the other. That's opening a different can of worms." and also to answer when to use one over the other: http://www.w3schools.com/php/php_get.asp
