Read It
Microsoft SharePoint Foundation 2010 includes many built-in content types.
All but one of these content types are derived from other built-in content types, and they can be organized in a hierarchy based on parentage.
How Its Done
At the top of the hierarchy is the System content type.
Next below System is the Item content type, which is derived from System and from which all other content types ultimately derive.
Finally
Here is the list of built in content type:
