Think of the DOM as a tree. It starts at the root of the browser’s display functionality: the window. From there, the page is encapsulated in window.document, with the page’s body in window.document.body. Then the tree fans out to every bit of content represented on the page. Most web pages have a very complex tree with many nodes finally ending in leaf nodes as the most granular pieces of the hierarchy.
