MP3

Perhaps you have heard your child or your child's friends use unfamiliar terms and expressions—such as "MP3," "Ogg Vorbis," "Kazaa," and "CD ripping"—and wondered just what they were talking about. Perhaps you have also heard about lawsuits stemming from the distribution of MP3 files and wondered if your child is involved in anything illegal. This section on MP3 technology is intended to help you understand what an MP3 file is, how one works, and how such a little file could cause such a big controversy.
