A simple explanation would be that:

A BOV discharges compressed air, inbetween the turbo compressor outlet and the intake manifold, upon release of the throttle to prevent compressor surge.

A Wastegate bypasses exhaust gas from entering the turbine inlet housing to regulate boost levels.

Hope that helps....
