Well, you've asked a pretty broad question. In the broadest sense the two things that are most basic are that helicopters turn the "wings" to create a relative wind and thus produce lift where as an airplane moves the entire aircraft to create lift. The tailrotor or tandem rotor (or even the second rotor on the same shaft) counteract the torque produced to turn the main shaft.

You need some basics, so start here:
http://www.helicopterpage.com/
http://www.verticalreference.com/vertical_reference_helo_aero_by_Rey.htm
http://www.copters.com/helo_aero.html (maybe a bit more than basics here)

There are tons of sites out there. Just go to any search engine and look up helicopter aerodynamics or helicopters and you will find a wealth of information.

If you have specific questions, feel free to ask them.
