When a wave bounces off a barrier and changes direction that is called reflection. Refraction, however occurs when a wave changed mediums, so if a wave were to go from moving in air to moving in water, the wave would change a direction that is based upon the index of refraction of that given medium.

So, if the answer is classifying a medium as a "boundary" then yes, they both change direction, however, a physical boundary only causes a change in direction in reflection.
