pub/sub model

The Pub/Sub model, short for Publish/Subscribe, is a communication method used in various systems and applications. In this model, "publishers" send messages or data without knowing who will receive them. The "subscribers" express interest in specific topics and receive messages related to those topics. This allows for efficient communication, as publishers and subscribers operate independently. It’s like a newspaper: publishers write articles (messages) on different subjects, and subscribers choose which sections (topics) to read, ensuring they only get the information relevant to them without direct interaction with the publishers.
