Answer
Publishes data to Subscribers. Frame the concept in practical terms so you can explain it during interview discussion.
In Reactive Streams, the Publisher is responsible for emitting data to one or more Subscribers, respecting backpressure. It's the starting point of a stream, providing items as requested by Subscribers. For example, a Publisher could be a data source providing stock prices to multiple clients.
