Ripping
To take off the audio or video from a CD or DVD. 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. Often Audio CD is "ripped" to MP3 files or DVD video ripped to .avi or .mkv files.
Encoding
Encoding is the process of changing data from one form into another according to a set of rules. The data is usually a file containing audio, video or still image. Often the encoding is done to make a file compatible with specific hardware (such as a DVD Player) or to compress or reduce the space the data occupies.
Common video encoding methods are DivX, MPEG-1, MPEG-2 and MPEG-4. A common audio encoding method is MP3 although many others exist including MPEG1 audio, DTS, and Dolby Digital.
Transcoding
A more technical term would be "The reformatting of content, without changing the source, to another type of content”.
Transcoding is the direct digital-to-digital data conversion of one encoding to another, such as for movie data files or audio files.
Compression
Data compression is the process of encoding information using fewer bits than the original representation would use.
Compression is useful because it helps reduce the consumption of expensive resources, such as hard disk space
Lossless compression removes only enough redundancy so that the original data can be recreated exactly as it was.
