+Publisher-Subscriber (Pub/Sub) is a [messaging pattern](/wiki/Messaging_Pattern) where information flows indirectly. Publishers broadcast messages to specific [topics](/wiki/Topic), unaware of who listens; subscribers declare interest in topics, receiving only what's relevant. This decoupling enhances flexibility in distributed systems.
