1.	What are content types in sharepoint
Answer» A content TYPE is a flexible and reusable WSS type DEFINITION or template that defines the columns and behavior for an item in a list or a document in a document library. For example, you can create a content type for a leave approval document with a UNIQUE set of columns, an EVENT handler, and its own document template and attach it with a document library/libraries.
