Publish-subscribe model
The publish-subscribe model is a communication pattern where messages are sent from publishers to subscribers without the two needing to know about each other. Think of it like a magazine subscription: publishers create content (the magazine) and subscribers receive it without direct interaction. In this model, publishers share information on specific topics, and people who are interested in those topics subscribe to receive updates. This approach allows for efficient distribution of information, as multiple subscribers can receive the same updates simultaneously, making it useful in areas like news feeds, notifications, and messaging systems.

The Publish-Subscribe Model is a communication method where one party, known as the publisher, distributes messages without directly sending them to specific recipients. Instead, interested parties, called subscribers, express their interest in certain topics or content. When a publisher releases a message, it is sent to all subscribers who have opted to receive updates on that topic. This model allows for efficient information sharing, as subscribers only receive relevant messages, while publishers can reach a broad audience without needing to know who the subscribers are. It's commonly used in news feeds, notifications, and event-driven systems.
