AC IS Alternating current while DC is direct current. AC is used to transfer the electricity to long distance while DC is used to transfer the electricity to short distance

AC can carry and safe to transfer longer distance even between two cities, and maintain the electric power.	DC cannot travel for a very long distance. It does, it loses electric power.
The rotating magnets cause the change in direction of electric flow.	The steady magnetism makes DC flow in a single direction.
The frequency of AC is depended upon the country. But, generally, the frequency is 50Hz or 60Hz.	DC has no frequency of zero frequency.
In AC the flow of current changes its direction backwards periodically.	It flows in a single direction steadily.
Electrons in AC keep changing its directions – backward and forward	Electrons only move in one direction – that is forward.
