Solution

3) Fundamentals of RPC

Remote Procedure Call (RPC) is a protocol which is based on distributed environment and make it look like as local environment, here one program can use to request a service from a program located in another computer in a network without having to understand network details.It allows a procedure to be either
local or remote and the application calls the procedure as if it were local. The calling application blocks until the procedure returns. The RPC(Remote procedure calls) are more complex to handle rather than local procedure calls as here messages may be limited in size. and as transmitted over network may be lost or reordered.Also as its distributed network which means different systems working on different architecture so setting up compatability betweent those is a challenge.
RPC therefore involves two components:A protocol to manage message passing between the client and server.Programming language and compiler support to translate a procedure call on the client into a request message and translate the message into arguments on the server and same of vice versa route.
