What's the difference between OpenID and OAuth?

What is really the difference between OpenID and oAuth? They look just the same to me.

OpenID is a way to specify one identity for multiple sites so you don't need to register over and over again.

OAuth is a way to allow one application access to one account without giving said application your account login information. You can use them in conjunction.
