iPod is a brand of portable digital media
player designed and marketed by Apple Computer. Devices in the iPod
family provide a simple user interface designed around a central
scroll wheel (barring the iPod shuffle). Most iPod models store
media on a built-in hard drive, while the smaller iPod shuffle and
iPod nano use flash memory. Like most digital audio players, an
iPod can serve as an external data storage device when connected to
a computer. 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 (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
which can play videos, the iPod nano which has a color screen, and
the iPod shuffle; all three iterations were released in 2005. The
iPod is currently the world's best-selling digital audio
player.
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.
