Superchargers and Turbochargers both do the same thing: they force more air into the cylinders, creating more power. The difference between the two is in how they get their energy to run.
With superchargers, there is a pulley attached between the turbune and the engine crank. There is some power loss because the engine has to also run the supercharger, but that loss is more than made up by the extra power from the supercharger. Also, since the supercharger runs off the crank, the power is always available.
With turbos, the turbine is spun using the pressure of the exhaust gases as they travel out of the engine. There is nearly no power loss like superchargers have. But, there is 'turbo lag' that delays the power burst of the turbo. When the car is at idle, there is very little pressure made by the exhaust gases, so it takes some time for the turbo to spin up and create the energy to force air into the cylinders.

Both push air into the intake manifold. Engines make power by exploding fuel but they need oxygen to burn the fuel. There is an ideal ratio of fuel and air to get the most power. So if you can pump more air into the cylinders then you can put more fuel and make more power.
OK. A turbo is like two fans on the same shaft. One is turned by the exhaust gas coming out of the engine. This turns the second fan which blows air into the intake manifold. Simple but you create back pressure and a lag between the time you step on the gas to when the turbo brings on the power. This is called turbo-lag.
A supercharger is an air pump that is driven by the crankshaft of the engine. Most use a wide belt on pulleys on the front of the engine. By changing pulleys you can adjust the amount of air that is pumped into the engine.
Superchargers are a little harder to fit into an engine compartment and cost more to manufacture. I think turbos will generate more heat under the hood. For a street car you have more parts to brake than a conventionally aspirated engine. So it's not that common to use either one.

Supercharged uses a gear or belt driven compressor that forces air into the intake ports.
Turbocharged uses the hot exhaust gasses that are coming out of the engine to turn the compressor that forces air into the intake ports.
Mercedes prefers Superchargers
Audi prefers Turbo Chargers
The advantage of a supercharger is no power lag
The disadvantage is that they consume HP to operate.
The advantage of Turbo charging, no power consumption
The dis advantage of turbocharging, short turbo life because of high operating temperatures.

well i would say the most obviuos thing is that the boost you recieve from a turbo occurs @ a certain rpm the boost you grt from a supercharger starts as soon as you hit the accelerator. superchargers also deal with pullys to create more hp as where a turo uses hot air to gain more hp

i believe turbo uses the exhaust to spin a turbine (for more air pressure in the cylinders) whereas superchargers spin the turbine through belts and pulley of the existing engine.

social heat couldn't have said it better.
For more torque you would want to go with a supercharger
for more top end you would want to go with a turbo charge!
But don't think that the turbo charge lacks great torque!!

a supercharge is mounted on to a intec manifold.
a turbo is mounted on to an exhaust manifold.
