Publish-subscribe is a messaging pattern in computer science that enables asynchronous communication by allowing senders (publishers) to broadcast messages to a central system without directly addressing receivers. Subscribers then receive only the messages they're interested in, promoting scalability and decoupling in complex systems like social networks or IoT devices. This model has evolved to handle real-time data streams in modern tech, making it essential for efficient, event-driven architectures.
