Answer:
COM Dll exposes Interface on the contrary to normal DLL
that exports functions. Clients create the pointer to
COMDLL's interface to call the methods defined by the
component that implements the interface.
That results in isolation of implementation and definition
of method in the interface. Client doesnt need to relink or
recompile the code if method in the com dll changes as far
as the definition of the interface remains same.
