As far as I'm aware the Cannon S2 IS does not have a RAW option. Most compact digicams store the photos in JPG format. This requires software in the camera to take the RAW data from the sensor and process it. When shooting RAW it is the data taken straight from the sensor that is stored. This generally results in much bigger files than shooting JPG. The big bonus is that as it contains the data just as it came from the sensor it can be processed on the computer using the setting the photographer chooses rather than automatically in camera. The type of thing this allows are adjusting the white balance and adjusting the exposure. It's just a lot more flexible but it does take more time in post processing as all the images have to be processed to get the best out of them.
