Topic Subscription

Topic subscription is a way for systems or applications to receive specific updates or information relevant to their interests. Think of it like subscribing to a magazine—by subscribing, you get only the issues you care about. In technology, a device or application subscribes to a "topic" to receive automatic notifications or data whenever there’s new activity or information in that area. This approach helps efficiently deliver targeted content without sending unnecessary data, enabling real-time updates and streamlined communication between systems or users.
