Streaming is transferring a nonstop flow of video data or audio and sometimes together at the same time. The term actually refers to the method that the data is delivered rather than the actual service. Streaming is a service that you are watching the data or listening to the service at the given time. It is not downloaded or stored. It is simply watching or listening to that data or audio at the given time. Watching a movie from a subscription service is a good example of streaming a movie.
