Streaming Media - Streaming media allows the user to watch and/or listen to a media file without it having first been fully downloaded to the user's equipment. A "player" and/or “browser” is most often necessary to view and/or listen to the file. Typically the streamed file is compressed before it’s sent to the user and decompressed by the user’s player/software for listening and/or viewing. The received file must be decompressed by the particular media player/software that's specified for that file.

This is the opposite of mp3 technology.
