In a distributed object-oriented environment, an ORB (object request broker) manages communication among objects and provides mechanisms for finding objects on a network that can satisfy a client request for services. It also prepares the target object to accept the request (there may be a difference in implementation). The ORB also handles the plumbing that allows objects to communicate over a network. For example, an object running on a client sends a message to an object running on the server by sending a message from its ORB interface (called a "stub") to the server's ORB interface.
