HIIT stands for High Intensity Interval Training. A form of cardio excercise using any cardio machine such as the treadmill and the elliptical trainer(which many says works best.)
Interval implies changing speed from low to high for about every 2 minutes when you exercise. By doing so, you avoid going to a steady state wherein your body adjusted already and would stop burning calories and fats.
It's best because you burn calories as long as you can still change pace. For how long, it will depend on you. The more you go up and down your speed, the more it is likely to be effective.
