Write one server and one client program. Test whether more than one client program can simultaneously interact with the server program. Describe the three alternative approaches to external data representation and marshalling. Sun XDR aligns each primitive value on a 4-byte boundary, whereas CORBA CDR aligns a primitive value of size n on an n-byte boundary. Discuss the trade-offs in choosing the sizes occupied by primitive values.
