Remote procedure call
In distributed computing, a remote procedure call (RPC) is an action in which a computer program causes a procedure (subroutine) to execute in a different address space of the current process (commonly on another computer on a shared computer network), which is written as if it were a normal (local) procedure call, without the programmer explicitly writing the details for the remote interaction. That is, the programmer writes essentially the same code whether the subroutine is local to the executing program, or remote.
