DOM stands for "Document Object Model". It's a way to treat elements of an XML or HTML document as objects. Each browser has it's own implementation of the DOM, but there are specifications provided by the W3 that define what the standard DOM methods should be. One example would be document.getElementById. The getElementById method is a standard method of the DOM.

Yahoo's library includes its own DOM Utility, which provides some methods not available in the standard DOM. For example, the standard DOM model defines a way to get an element by an ID value (getElementById), but does not provide a standard way to get the elements with a particular class (Note, that is coming in a future version of the DOM). The Yahoo UI Library provides a method for doing that: YAHOO.util.Dom.getElementsByClassName.

Hope that helps.
