View Mode: Each content type can have various view modes. This is a way of outputting a node in a specific format with a specific set of fields. What we're calling a Preview is a view mode. So a preview is a pre-defined way of outputting a node that can be used all over the site. View modes are built by developers and are not configurable by content editors, but they can edit nodes to change the content of a preview.
