Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.

What are some examples of pneumatic devices?
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Is a jackhammer a pneumatic or hydraulic system?
a jackhammer uses a pneumatic system.the jackhammer is a direct combination of a hammer and a chisel
How is hydraulic system better than pneumatic system with a brief disicussion?
Difficult question to answer without context. Key thing to understand is a pneumatic system uses a compressor, whereas a hydraulic system uses a pump. Hydraulic fluid is essentially incompressible, whereas compressed air will fill any volume. Ask yourself: What is my pneumatic/hydraulic system supposed to do? How fast should it react and what horsepower is available to drive my compressor/pump? What force do I need at my actuator/motor or whatever the system is expected to power? Generally, I think pneumatic systems can react more quickly but power density is lower, so if the load is very high a hydraulic system might be better. A typical shop pneumatic system might only operate at 50psi, whereas a hydraulic system can operate at 3000psi. Finally, it's also worth thinking about system safety: if a pneumatic component fails, there will be an explosive decompression, but if a hydraulic component fails, it will leak but will not explode because hydraulic fluid does not store energy, it only transmits it.
Are Dam hydraulic or pneumatic?
It depends on the dam. Some dams are hydraulic and some are pneumatic. Short answer: Both
Is a volcano a Pneumatic or hydraulic system?
Elements of both but the molten rock pyroclastic flows (Mauna Kea , Hawaii) are hydraulic, the Mt. St Helens eruption was to a large extent pneumatic as the water turned to steam.
What does hydraulic and pneumatic systems have incommon?
both pneumatic & hydraulic systems are applications of fluid powers
How does a pneumatic differ from hydraulic system?
Transmission fluid is performed by the hydraulic system. Pneumatic power transmission system is done by the gas.
Are all cranes hydraulic?
It may be hydraulic or pneumatic system

Pneumatic brake system?
Used in trucks and buses. This type of braking system of pneumatic and hydraulic hybrid vehicles.
Do pneumatic have less power then hydraulic?
Yes. Though the response time of a pneumatic system is better as compared to hydraulic, power output is higher in latter.
What kind of energy does a car jack use?
Mechanical, hydraulic and pneumatic are the main ones.
Why is the pneumatic system less reliable then the hydraulic system?
Gases can be compressed. Liquids can't.

Is a backhoe loader hydraulic or pneumatic?
its hydraulic.
What type of brake fluid does the pneumatic ABS system use?
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.
