DC signals have current constantly flowing in one direction, at a usually steady pace. The voltage of the source is unchanging. The two terminals of the source hold their outputs at the same voltage difference as time progresses.
AC signals have an interesting wave pattern to them. The current alternates back and forth, because the voltage oscillates positive and negative (relative to the neutral terminal). If you examine the electron behavior, it will appear as a longitudinal wave of electron compressions and voids.

AC power transmits way better.
most power users, lights, motors, heating elements, etc can use AC power just fine.
however, all electronics components use transistors, diodes, capacitors, etc, which require DC power.
in DC, the electrons all flow in the same direction. solid state electronics need that.

AC power is more efficient for distribution to homes whereas DC power is required for electronic devices see http://www.satcure-focus.com/tutor/page1… for a comprehensive comparison between the two.
