There is no difference between a B-spline curve and a curve that consists of Bezier curves as segments because a B-spline curve is a curve that consists of Bezier curves as segments. However, there is indeed differences between a B-spline curve and a Bezier curve. For Bezier curves, changing any control point will affect the shape of entire curve. For B-spline curves, changing any control point will only affect (degree+1) Bezier segments.

B-spline curve is not the only type of curve that consists of Bezier curves as segments. Catmull-Rom spline and cubic Hermite spline are two such examples and both of which can be converted into the form of B-spline curves.
