RPC Explained: What is Remote Procedure Call?

RPC (Remote Procedure Call) is a protocol that allows a program on one computer to call a subroutine or function on another computer without having to understand the network details. It's a client-server communication model where the client sends a request to the server, and the server processes the request and sends a response back to the client. RPC is used in distributed computing environments to enable communication between different systems and applications. It can be used to implement distributed applications such as file sharing, distributed databases, and remote procedure invocations.
