The majority of ipod models store media on a built-in hard drive, while the smaller ipod shuffle and ipod nano use flash memory. An ipod, like most digital audio players, can serve as an external data storage device when connected to a computer. The discontinued versions of the ipod include two generations of the popular ipod mini and four generations of the full-sized ipod, all of which had monochrome screens except for the fourth-generation ipod with color screen, which was previously sold as ipod photo before it replaced the monochrome ipod in the top line. As of December 2005, the lineup consists of the fifth-generation ipod that can play videos, the ipod nano that has a color screen, and the ipod shuffle; all three iterations were released in 2005.

The bundled software used for uploading music, photos, and videos to the ipod is called iTunes. iTunes is a music jukebox application that stores a comprehensive library of the music on a user's computer, as well as being able to play and rip it from a CD. The most recent incarnations of ipod and iTunes have video playing and organization features. Other forms of data can be added to ipod as if it were a normal data storage device.

Apple’s latest iPods are built primarily for playing music, but don’t forget they come fully equipped with superb multimedia features. So if you thought they were just for listening to music, think again. You can also view photo albums, play games, and watch movies, and more. And the performance is superb due to advanced technology that uses Mp4 encoding.
