Access to resources of various machines is done explicitly by Remote logging into the appropriate remote machine Transferring data from remote machines to local machines via the File Transfer Protocol FTP mechanism Tightly Coupled Distributed System The advantages are inherent in the architecture External commonmode noise sources from the power supply and other circuitry are rejected by the differen tial nature of the architecture Evenorder harmonics tend to cancel The required voltage swing 1 RMI Distributed Software Systems RMI Middleware layers Applications, servicesMiddlewarelayersrequest-reply protocolmarshalling and external data representation RMI and RPC 2 RMI Distributed Objects Overview of .
