 A message that is sent (the send-operation is often called "*publish*" in this context) to a *topic* is broadcasted to all consumers that have *subscribed* to the topic.
 
 A message that is sent to a *queue* is processed by a message *consumer* (usually exactly once although some message systems support a more performant at-least-once mode for messages with [idempotent][] processing).
