Your car burns fuel and air. Once this happens, it creates exhaust gas which is expelled through the exhaust. Enter the turbo, the turbo is placed right after the exhaust manifold and has two two turbines ( intake and exhaust) contained in the turbine housing. The turbo utilizes otherwise wasted exhaust gas to spin the exhaust turbine and correspondingly spin the intake turbine, thus compressing and forcing more intake air into each cylinder and making more power. This is all controlled by the waste gate which sits next to the exhaust turbine. When the car controls boost it opens the waste gate and basically bypasses the exhaust turbine and controlling how fast the turbine spins.

That's it in short.
