What is Really Ripping......

Ripping is the process of copying audio or video content to a hard disk, typically from removable media. The word is used to refer to all forms of media. Despite the name, neither the media nor the data in it is damaged after extraction.
Digital Audio Extraction (DAE) is a more formal phrase applied to the ripping of audio CD's. Ripping is distinct from simple file copying, in which the source audio/video is not formatted for ease of use in a computer file system. For example, the hierarchy of files making up the audio/video data on a DVD-Video disc can be encoded into a single MPEG file. In addition, the copied data are often compressed with appropriate codecs. Ripping is often used to shift formats, and to edit, duplicate or back up media content. Media files released on the Internet may describe the source of the rip in their names, e.g. DVD-Rip.
