Remote Procedure Call (RPC) is a powerful technique for constructing distributed and client-server based applications. Majorly RPC is used to call other processes on the remote systems like a local system. RPC is a method of modelling communication between two applications as straightforward function calls. Although the applications may be on different machines, an RPC mechanism usually defines a network protocol. It is a format for exchanging messages, a portable way of serializing and deserializing data and specific programming language support.
