You can call methods of CORBA Objets (Servers) from everywhere. Consider you
have implemented an 'Echo' server:

interface Echo {
        void echoString(in string astring);

all you need is to get a object reference to that server. Then you can call

 Echo_echoString(echo_client, "test", ev);

That's all, no matter where the object (server implementation) is located. You
can implement the server inside a shared library, it can be a separate process
on the same computer, or it can be located somewhere in the world (accessible
through the internet (TCP/IP)- or other network protocols). I think the
call that 'location transparent'.

I hope this answers the question?
