Registered Server v/s Linked Server

Hello All,
What is the difference between a registered server and a linked server? If
in Query Analyzer one can reference objects using fully qualified names in a
linked server like this:
SELECT * FROM LinkedServer.Northwind.dbo.Products
why can't one do the same by registering the remote server (which is in the
same domain) and then referencing it?
Thanks somebody; help please. This has me baffled!
Jerome SmithRegistering servers if for the mmc console and information
that the snap in needs to access the server. A registered
server in the mmc console doesn't know anything about the
other registered servers, just the mmc console does.
With linked servers, the information is for SQL Server
itself so that it can access data or do whatever.
If registering servers automatically allowed the
functionality of linked servers, you'd lose a lot of control
over security, distributed queries, etc.

Now I still have the question: what is the purpose of registering servers?
What can one do with registered servers?
Thanks again.

one mmc console using Enterprise Manager. A registered
server gives you access through Enterprise Manager.
