Definition

A message is an information sent by a sender process to a receiver process. A message queue is a mechanism that allows a sender process and a receiver process to exchange messages. The sender posts a message in the queue, and the receiver retrieves the message from the queue. A message queuing system provides a means to build distributed systems, where distributed processes communicate through messages exchanged via queues.
