RPC

R emote P rocedure C all protocol that allows a program on one computer to execute a program on a server computer. Using RPC, a system developer need not develop specific procedures for the server. With RPC you call a specific function whereas with an ORB you call a method within a distributed object. In ORB each object manages its own private instance of the data whereas in RPC you can only call a specific function and all functions get implemented in the same way. ORB allows for differential processing. See CORBA .
