Answer : MFC is one of the ways to create a com DLL along with ATL.

COM(Component Object Model):
Technology that allows you to use functionality from other softwares(like MS-WORD,IE,MS-OFFICE etc) in your VB/VC/VJ/VFP application. Technically COM Components expose certain Properties ,Methods, and Events to your Application.

MFC extension DLL:
It is a DLL that typically implements reusable classes derived from the existing Microsoft Foundation Class Library classes.
