It evolved like this
when u write a CLASS to reuse in a application, multiple
intances of the class exists with each instance of
application,
Next u want to avoid it so u make a class and put it in DLL
now only one instance exists though multiple instances of
applications exists
Applicatoin needs to be recompiled whenever Dll is
modified, SO came COM.
COM is independent component that internally handles
networking, resources etc, COM uses IDL to communicate to
different languages
