what is a node?

Question

a Brief explanation would be appreciated.

Answer 1

When a browser loads an HTML page, it creates a model of that page called a DOM tree, and stores it in the browser's memory.
A DOM node is every element, attribute, and piece of text in the HTML. At the top of this DOM tree is the document node, which is the parent of all nodes and these are descendants of the document node.
Relationships between the document and all of the element nodes are described using the same terms as a family tree: parents, children, siblings ancestors, and descendants.
