It's a way to describe the structure of a XML/HTML document. DOM describes the hierarchical structure defined by tags in such document types. Elements can have children and/or parents. The mapping of the tag hierarchy is done in a tree structure and called DOM. It's a object based model who describes this paradigm and represents it. This is a HTML document which may be represented in a DOM: <html> <head> </head> <body> </bod> </html> parent: html, children: head, body

In the case of Javascript/HTML all tags which are part of the loaded site are also part of the DOM. If you modify the DOM and add or remove tags through JS the DOM gets modified. But I'm not sure if I understand your question correctly.
