White balance is the term used to describe how does the camera balance the temperature of the image. As the name suggests, it's balancing the camera to the right temperature of color so that white is white.

I think it is where you can change it to black and white or sepia or vibrant. I had that on my camera. You can change it on the camera before you take the picture.
Per my understanding the difference is that auto white balance makes the automatic adjusting of white balance only once at a time, for example only, when camera is powered on (and a blank white card is put in front of it). While auto tracking white balance function provides continuous real-time monitoring and adjusting of white balance in real-time as lighting conditions change (for instance day exterior changes to tungsten exterior).

The white balance feature compensates for the quality of light in the area you're using the camera in. You know all the pictures your mom has in her photo album that they took in the kitchen, that are this real ugly orange? They're that way because the film they used is balanced for daylight, and the light bulb in the kitchen makes light that's a lot redder than daylight. To use the white balance control, follow the instructions in the camera manual but the ones I've seen have you point the camera at a white thing and push the button. The camera will adjust itself to make the white thing look white.
...The simple answer is that white balance adjusts camera color response so that a white object in life appears white to the camera. Various sources of illumination may cause white to appear bluish or reddish. White balance settings add or subtract needed colors to force white objects to record as white objects. The idea is that if white is made to look white, other colors will also look correct in the digital picture. For example, objects viewed under fluorescent lighting tend to appear bluish in a picture. With the proper color correction using a white balance setting, objects will appear true to color without a bluish cast. ...In reality, it is sometimes difficult to completely correct color casts and automatic white balance settings do not always give the best results. Mixed source illumination is sometimes difficult to control. One way to check white balance is to look at a white card in your viewer and change white balance settings until the card actually looks white. Post color correction using software can also help make this correction.
There are two types of bracketing: auto exposure bracketing and white balance bracketing. Auto exposure bracketing makes the camera take three (or more if you shoot Nikon) images in rapid succession. Each of the images will capture a different exposure. The first shot will be neutral exposure, the next shot will be a lower exposure (darker) and the last picture will be brighter. This helps if you're in a situation where you're not sure what the correct exposure would be. Also, it is used in HDR imagery. White balance bracketing does the same thing except you are bracketing the white balance with each shot. This is useless if you shoot in RAW because you can simply change this afterword.
The white balance of the camera is using the surrounding light to judge the color temperature of the room. The iPad uses an LED backlight, which may photograph with a blue tinge. Try shooting it with a halogen light or natural sunlight. It should move the white balance away from an indoor yellow tinge.
Something that's perfectly white. A good one that you could stick in your camera bag is a four-inch ceramic wall tile.
