Direct vs indirect memory access
WebDirect vs indirect One of choices IPC designer have to make is if message passing is direct or indirect. In direct message passing, receiver identity is known and message is sent directly to the receiving process. We can say that there is a link between two processes exchanging data. There cannot exist more than one link between any two processes.
