Remote Procedure Call (RPC)

Remote Procedure Call is a communication protocol that allows a software program to execute a procedure on any other computer or server (mostly remote, without a need to understand the network’s details; when a developer runs a program on RPC, a helper part called Stub is included, which acts like a remote code. When the program functions and tries to employ the remote code, the Stub receives a request.

The Stub sends this request to another helper program on the same computer. Then, the helper sends a message over the internet to another computer, asking it to run the code. As compared to other communication methods, RPC enhances overall performance.
