Message passing refers to the messages that information systems pass among themselves, achieving thereby some kind of distributed computation. Message passing systems use some form of inter-process communication provided by the platform.
Description
In message-passing systems, one system makes a request, and another provides a response. The requestor is called the client, and the responder is called theer server. These roles exists even in peer-to-peer systems, where the participants take on one role or the other for the duration of the conversation.
