The following video describes and defines a series of different holds for rock climbing. These are somewhat basic terms for what you will find in both a indoor gym environment as well as in an outdoor setting.
The preceding video skips a specific series very important definitions. It completely skips hand jams and crack climbing. As the video was produced in a gym and there aren't very many cracks in gyms, this isn't that strange. The following video addresses this kind of climbing.
