A content type is an information blueprint basically that can be re-used throughout a SharePoint environment for defining things like metadata and ASSOCIATED behaviors. It is basically an extension of a SharePoint list, HOWEVER makes it portable for use throughout an instance regardless of where the INSTANTIATION occurs, ergo has location independence.

Multiple content types can exist in ONE document library assuming that the appropriate document library settings are enabled. The content type will contain things like the metadata, listform pages, workflows, templates (if a document content type), and associated CUSTOM written functionality.
