According to a definition on Wikipedia, “In distributed computing, a remote procedure call is when a computer program causes a procedure to execute in a different address space, which is coded as if it were a normal procedure call, without the programmer explicitly coding the details for the remote interaction.” Broadly speaking, Remote Procedure Call is a protocol that one program can use to request a service from a program located in some another computer on a network without having to understand the network’s details. RPC is used to call other processes on the remote systems like a local system.
