Alternating current is produced by an alternating voltage which is periodically changing in polarity like pushing then pulling.  Direct current flows the same direction as the voltage polarity is constant.

Dear sir,
     I thank you very much for your support regarding my qustion.But i'm very sorry Because, im trying to have an explanation regarding  the behaviour of electrons with Ac conduction and change in behaviour of electrons with Dc conduction. I request you to give explanation in form of, change in the movementum of  electrons in a substance with ac and dc rather than the waveform.

I don't believe I know the exact mechanics of individual electron movement, except the electrons that are mobile are loosely held in the outer orbit (valence electrons) of the conducting elements when a potential is applied the drift becomes less random and is influenced by the potential difference as exhibited by the beam of electrons in a klystron.  This beam can be influenced by placing potentials on the beam forming elements.  The acceleration of the beam can be increased or decreased by the presence of voltages on the grids.  As far as the actual dynamics of the electrons while in "flight" I dont know.  They do try to diverge, and forming the beam and keeping it in a beam requires some effort.
