A digital music player is a device capable of playing digital music files. 
A portable digital music player contains FLASH RAM to hold about an hour's
worth of music transferred to the player from a PC hard drive. Some portable 
players have hard drives instead of the FLASH RAM, so they can hold many hours
of music. 

A networked digital music player, such as the Turtle Beach AudioTron(TM), 
streams music from a PC hard drive over a network connection so that the 
digital music on the PC can be played from anywhere in your home. Unlike a CD 
Player or even a 100 CD-changer, a network digital music player offers much 
more flexibility in listening to a large library of music and lets you enjoy 
Internet music downloads on your stereo system or home theater.
