What kind of applications use the sound on Internet:

RealAudio uses a system of 'streaming' - the audio sound streams down the Internet to your computer, playing directly through your speakers. Unlike e-mail and other data, it is not split up during its voyage through the Internet. This is different from 'downloading', as there is no actual file transfer. Additionally, the RealAudio software should be launched automatically by your browser. It also has the added benefit of leaving the user in full control. The RealAudio software allows you to rewind, stop or fast-forward the sound. Even better, you can still 'surf' about on your browser while the sound is playing.
