general rundown? exhaust gas turn a turnbine in the turbo, which turn a turbine in the intake, which pressurizes the air, (Hence the amount of boost), which makes you go faster. Hope this helps.
The higher the RPM's the faster the turbo turns, the more boost you make.

Short and sweet is the exhaust spins a turbine blade, which is turn attached via a shaft to a turbine on the intake side. Motor runs, exhaust gases trun the turbine on exhaust side, which in turn runs the turbine blades (compressor) on the other end of the shaft. Thus compressing the intake air and forcing more air into the cylinders. A top line system also has a cooler to cool the compressed intake air. More air into the cylinders=more fuel supply=more hp and torque. There is a lot more involved, but that is a short description.

Nothing to add except this. A turbo is a supercharger but simply a different type. It's full name is a turbosupercharger. It's actually a bit more efficient overall than a belt or otherwise mechanically driven supercharger. In other words, it requires less HP to operate for a given HP gain. But that being said, both types have their pluses and minuses that need to be considered for a given application. I like the turbo better for a street application because there is less drag during normal driving, hence I believe you could achieve better overall economy with one. A standard supercharger is more responsive from a wider range of engine speeds. This is a very broad overview (and I'm far from an expert in the matter) but something that will hopefully encourage you to do more research on the subject, if you're considering either.

So were the DDE 6V92 & 8V92, but they both were better as boat anchors.
Ever been around when someone puts on a new turbo, doesn't prelube it and fires the engine up. It sure makes some screechy sounds right before it comes apart.

A co worker of mine was involved from beginning to end in this expedition to recover a P-38 lost during WW2 below 300 feet of ice. If you have the time to read it it's a fascinating story. He was one of the guys that was lowered 300 feet below the ice, then dismantled the aircraft piece by piece, and hoisted it to the surface:

The pictures and story's he tells of that expedition are nothing short of extraordinary.
I used to be involved in a lot of vintage war aircraft restoration work but nothing near that level. Most of the planes we worked on were recovered from the bottoms of bodies of fresh water.

I use to be a Turbo Mustang guy.. 
But.. we had an article for those that were new to turbos, and it would likely prove useful to you:
