What are hydraulics and Numatics? ( That might have been a typo... )

Hydraulic means fluid power, or using a liquid to create linear motion.
A good example is a floor jack for your car, or even the strut on a car's trunk
Pneumatic means powered by air. The impact guns nascar guys or even your local auto shop use are powered by compressed air.

Thank you, this will help my homework that I am pretending to do whilst playing spider solitare. I just got a 76% win ratio!

You will find that doing home work and learning from it is more beneficial than wasting time on games. Of course by the time you figure it out, it will be too late.
