[RESOLVED] What does this line mean??

These lines are taken from MSDN. I just dont understand the
meaning of this .....

"Referring to an object implementing an interface means that the object uses code that implements each method of the interface and provides COM binary-compliant pointers to those functions to the COM library. COM then makes those functions available to any client who asks for a pointer to the interface, whether the client is inside or outside of the process that implements those functions."

Can someone please help me?

Sid.
