Kata is a system of movements (forms) used in martial arts training. They often consist of karate blocks, kicks and strikes organised into a pre-arranged fight against imaginary opponents. One of the benefits of course is the applications you get from kata.
Bunkai is the practical application of kata against real life opponents in pre-arranged form.
