Answer
An entity that produces data and sends it to subscribers.
In the Reactive Streams specification, a Publisher is responsible for emitting a stream of data items to a Subscriber. It controls the flow of data and backpressure, ensuring that the Subscriber receives data at a manageable rate. For instance, in a live price update system, a Publisher would emit price changes as they occur, which are then consumed by Subscribers interested in those updates.
