Generally speaking:
Fulltime or Constant 4WDs have a center differential which allow the front and rear tailshafts to spin at different rates (avoiding gearbox damage among other things). They usually have a center diff 'lock' to force the two tailshafts to spin at the same speeds (just like a (usually) chain-driven part-time 4WD).
Any vehicle requires the front wheels and rear wheels to spin at different rates otherwise you can quickly do damage to your vehicle. Usually when you use 4WD, the ?dirt roads provide enough slip for the wheels not to do as much damage as it would on hard grippy tarmac.
