I thought this might be a question. I will put it up on the OP, but the difference and extent is as follows. 

A cyborg, at this point the in time, will be some one with a majority of their body robotic or augmented. The advancements are not as far as in the Ghost in the shell, but you could enhance legs and arms to be classified as a cyborg. Cyborgs have their disadvantages both in limitations as well as social view. 

Enhanced Human would be minor enhancements to mental abilities rather than physical. Enhanced have limits as well, but not as much bad rep in the social realm.
