RAW is the sensor dump. All kind of software filters, white balance are applied after that by the camera's software. That so is named the "digital negative". You can "develop" you jpg from that RAW data file. Sometimes it is very useful to shot in RAW because you can "save" a photo.

RAW is a CCD or sensor dump from your digital camera. The camera records every pixel's value and stores the information as is. There is no in camera image processing or lossy compression (as with jpeg).
JPEG is an lossy image file format that almost any image viewer can open and used very widely due to small file size. However, lossy compression cannot be reversed after compression. Plus the camera may apply processing to the image that you may not want.

Raw is an uncompressed image file. JPGs are compressed image files, compressed using of scheme that causes some inevitable loss of data upon opening and or saving. Raw images can be opened with a sophisticated image editing application such as Photoshop. For archival or heirloom work, as well as professional work, Raw would be preferred.
