The key light is the main source of light and is key to the whole set up, it is angled 45 degrees from the camera, so it is not faced on and it won't look as well defined, so at the 45 degree angle she looks well defined as wrapped around the face, apart from a few shadows, which is where you use the fill light to get rid of them.
The fill light is also placed at a 45 degree angle from the camera, however is opposite from the key light. The fill light is less intense than the key light, you can do this by using a lamp, or simply moving the light further away as this effects the light tensity, also you can use a density gell. Using key light and fill light creates an even light around the subjects face and helps them blend into the background.
The back light is used to make them stand out of the background. The light is placed behind them but not at the camera, and this creates a rim of light behind their shoulders and their head, to make them stand out of the back ground, so in the end once used all 3 together, the subject looks really good.
