Multiple templates can be applied to the same object to produce different presentations. A template is normally stored as a file in a source code management system and managed as code. There will normally be at least one template per content type.
In some CMS, the term "content template" (or even just "template") is used to refer to content types. In those systems, templates (as defined here) have a different name or modifier ("renderings," "rendering templates," or "output templates" for example).
"Template" is occasionaly used as a verb to mean the create of a template to apply to a content object: "We need to template this content type."
