Final answer:
Messages in the referred method are placed in queues, a part of asynchronous communication in systems that allows for decoupling and flexibility.
Step-by-step explanation:
In the case you are referring to, messages are not sent directly from sender to receiver but rather are sent to a shared data structure consisting of queues that can temporarily hold messages. This method of communication is often used in computer science, specifically in areas like concurrent programming, distributed systems, and message-oriented middleware. It is a core concept in the development of robust, scalable systems, and it allows for the decoupling of processes, which ensures that a system can continue to operate effectively even if parts of it are slow or failing.
The asynchronous communication model, which this system adheres to, provides the capacity to communicate messages that are not definite or limited in terms of possible content, topic, or type. In other words, it allows for a flexible messaging scheme where messages can be enqueued and later retrieved by the intended recipients, without requiring a direct and immediate connection between the sender and receiver.
