Distributed Computing and XML Web Services

I was invited at MAJU to deliver a presentation to final year students. There I talked about "Distributed Computing", and how it was being done using technologies like CORBA, DCOM , RMI etc. I told them why do we need a paradigm for distributed computing that ensures loose coupling and is based on standards. I told them about XML Web Services and its underlying architecture. I also discussed find,bind and execute feature of service orientation. Students liked the stuff pretty much :)
