a: Simple. Superchargers spool from intake air and increases the pressure and forces it into the combustion chamber, and it provides low end torque and power. It requires no blow off valve because the air can decompress back through the intake tube. A turbo uses exhaust air and spools up pushing the air the same as the super, but gains boost the higher in the rpm range, creating high rpm torque and power.
now that is some serious nonsense right there.
