The client invokes a method on a remote object. The ORB locates an instance of that object server class, invokes the requested method and returns the results to the client object. Server objects must provide support for...

If the bulk of the application runs on the Client side, then it is Fat clients. It is used for decision support and personal software.If the bulk of the application runs on the Server side, then it is Fat servers.
