Definitions for "Message queuing"
A model similar to that of message passing, but with one additional feature: Message queuing is asynchronous in a manner similar to a traditional postal system — that is, the recipient need not be available when the message is sent. Message queuing stores messages at an intermediate node on the network in a queue and then forwards the messages to the intended targets. See message passing.
A form of communication between programs. Application data is combined with a header (information about the data) to form a message. Messages are stored in queues, which can be buffered or persistent (see Buffered Queue and Persistent Queue). It is an asynchronous communications style and provides a loosely coupled exchange across multiple operating systems.
Server technology developers can use to build large-scale distributed systems with reliable communications between applications that can continue to operate reliably even when networked systems are unavailable. This technology is being developed in the Microsoft project code-named "Falcon."
An ordered list of messages awaiting transmission, from which they are taken up on a first in, first out (FIFO) basis.
