RPC

RPC, or Remote Procedure Call, is a method that allows a computer program to request a service or perform a function on another computer or server over a network, as if it were calling a local function. It simplifies complex interactions by hiding the underlying communication details, enabling seamless integration between different systems. Think of it like making a phone call: you dial a number (send a request), and the other person responds, but in this case, the "call" executes code on a remote machine, and the results are returned to your program.
