Cars have several hydraulic systems in them.
Cooling system: water-cooled car engines have fluid flowing around the combutstion chambers at temperatures above 212F at pressures above atmospheric pressures. Typical modern sytems run at peak temps. of 238F and have 15 psi reliefs with 190F thermostats.
Lubrication system: Oil is pumped to bearings and valves in the engine, as well as the bottoms of pistons and cylinder walls. This prevents sliding and rotating parts from having metal-to-metal contact, reducing wear.
Power Steering: Oil is pumped to a high pressure servo valve which assists the driver by pushing the steering right or left as required.
Brakes: Very commonly associated with hydraulics because of the amplification of force from the foot pedal to the brake pads. A piston on a lever forces thin brake fluid onto pistons on the brake calipers, forcing friction material against the brake disk.
Air conditioning: A pump moving R134A changes the phase from liquid to gas to acheive passenger compartment cooling.
Shock Absorbers: In engineering terms a shock absorber is a damper. The faster you displace the end of the shock, the more force it resists the motion. Energy is dissipated in the fluid inside the shock. Valves modify the flow rate and the forces acting on the wheel displacement.
Fuel Injection: Fuel at a low pressure enters the fuel pump and is delivered to a fuel rail to the fuel injectors. A manifold pressure regulator determines the bulk fuel flow rate to the engine based on engine load. The injectors are pulsed by the engine computer which can make small adjustments to the flow rate and help maintain low emissions.
Automatic Transmissions: Fluid is used to mechanically couple the engine to the transmission and drive train through the torque converter. The benefit of a flid coupling is torque multiplication. It allows the engine to rotate even if the car is stopped. As the vehicle accelerates, it acts as a continuously variable transmission which automatically makes more torque when the car is moving slowly and attains higher speeds as the car gets moving.

Hydraulics are the substance which are compressible in nature and hydraulics means fluids or oils. They are use in actuating the steering system. Ease the brake for the driver in sports car because the braking force required is very high and it is too much for the driver to bear, so the power actuated by hydraulic and to the brake circuit. Use in suspension for better suspension and effective vibration damping in sports cars. Used to change the gears in high end car like F1 cars. It is used to engage the clutch in a manual gear sports car.

Skynet:
Hydraulics is the mechanical science dealing with liquids, especially those under pressure. ( hydro is the Latin word for water) The Braking System and the Power Assisted Steering system would be examples,
It may also have some "slang" meaning, but I can't help you with that.

well for lowriders... its what make their cars "HOP" something on your car that will cause something to rise or move MECHANICALLY upon your control of the hydraulics

Shocks, brakes, automatic transmission(?), hood & trunk openers
