WebIn computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer. The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code. WebIn an operating system, remote procedure call (RPC) has the following features, such as: RPC hides the complexity of the message passing process from the user. RPC only uses specific layers of the OSI model like the transport layer. Clients can communicate with the server by using higher-level languages.
