Node visibility refers to whether or not some published content can be viewed on the front-end of a site. Hiding a node will render the target node and the entire subtree below it invisible. This is the correct way to "unpublish" content without deleting it or moving it to a restricted section.
The three visibility statuses are "visible", "hidden" and "hidden by superior". You can alter the visibility status of a node from the pop-up menu or the Locations window.
