What is the equivalence of ActiveX, COM, COM+ and DCOM in .NET

I know there is no 100% equivalence

Thank you.
 
ActiveX - .NET Controls
COM - .NET itself
COM+ - .NET still uses COM+ services
DCOM - .NET remoting

First Thank you
I don't understand ActiveX as .NET Controls
Possibly more than that like including HTML Behaviors??
Also How about COM - Is it .NET itself or the Assembly that is self
describing?
What is COM+ do? is it like remoting?

What do you think
Thank you again and I hope you will give me your expert thoughts

ActiveX is really only a marketing name for a COM component that implements
certain sets of interfaces. Similarly, in .NET WinForms, there are .NET
controls that can be dropped into a GUI and they're just .NET classes that
implement a required set of interfaces and behaviors.
Possibly more than that like including HTML Behaviors??

I don't know what you mean by that. AFIAK, there's no bdinding to
client-side .NET controls in HTML (yet), but I could be mistaken about that.

describing?

..NET assemblies are self describing, much like a COM component and it's type
library, but at a much higher level of detail.
What is COM+ do? is it like remoting?

COM+ is a collection of object services such as automatic transactions,
queueing, etc.
