Sharable Content Object Reference Model. This standard seeks to track and manage courseware developed by various authoring tools using a single system.

Streaming media technology enables the real-time or on demand distribution of audio, video, and multimedia on the Internet. Streaming media is the simultaneous transfer of digital media so that it is received as a continuous real-time stream. Streamed data is transmitted by a server application and received and displayed in real-time by client applications. These applications can start displaying video or playing back audio as soon as enough data has been received and stored in the receiving station’s buffer. A streamed file is simultaneously downloaded and viewed, but leaves behind no physical file on the viewer's machine.
