difference between resistance and impedence

In AC circuits, "impedance" generalizes "resistance" by Anon User is a sensible statement giving the angle they are trying to get at, but slightly misleading in my opinion, i would personally say people useResistance to generalise Impedance.
Resistance is a concept used for DC (direct currents) whereas impedance is the AC (alternating current) equivalent.
Resistance is due to electrons in a conductor colliding with the ionic lattice of the conductor meaning that electrical energy is converted into heat. Different materials have different resistivities (a property defining how resistive a material of given dimensions will be).
However, when considering AC you must remember that it oscillates as a sine wave so the sign is always changing. This means that other effects need to be considered - namely inductance and capacitance.
