COM is simple. COM defines a binary standard. It does not describe how the various programming languages may be bound to it.
COM also includes a set of services, ie API's. These API's include various helper functionsfor the COM programmer
COM is object oriented. Each COM object has its own identity and state.
COM objects can link dynamically. Just visualize them as plug and play devices on your computer: just plug it in and it starts working. Pull it out when you don't need it.
COM enables you to create distributed applications too. You don’t even have to know wherethe COM object resides when you call it. It could even reside somewhere on a remote computer.
COM applications can be written in any programming language.
