Because of the independence of the layers, when you select a network (i.e., AppleTalk, Ethernet, Token-Ring), your choice can be made without regard to the specifics of the lower functions.  

This points to the interchangeability of layers inherent in the OSI model.  The lower functions can be changed without affecting any of the other layers.
