The 1 gap 34 is a predetermined lane/gap assignment by the defensive line/front. They know which slot/gap they will attempt to penentrate prior to the snap. This is supposed to force the offensive line to adjust to the defensive player. It is an "attacking" type of 34 defense.
A 2 gap is a read and react gap choice made by the defense at the time of the snap which is meant to have the defensive player control the offensive line as they move with the play. The defensive line is meant to control the offensive line players, holding them up, controlling the point so that the linebackers and safeties can make a play on the ball. It is a "controlling" type of 34 defense.
That's the basic differences.
