Difference between a dynamo and an alternator

Any device that converts mechanical energy into electrical energy using electromagnetic induction is a generator. Both dynamos and alternators are generator, but the former uses DC, direct current, while alternators use AC, alternating current. Also, dynamos aren't really used anymore.
