How Does the iPod Nano Work?by Stephen Lilley
The iPod Nano was introduced by Apple in 2005 as a smaller, lighter, more user-friendly version of their traditional iPod MP3 player. Due to its smaller size, both physical and storage-wise, it is considered a "mid-range" model in the iPod line of products. As opposed to an internal hard drive, it uses flash memory, has a 2-inch screen and features a click wheel used for scrolling through menus and songs. Since its introduction, the iPod Nano has gone through four model changes, or "generations," (as of April 2009), with the most recent being released in September 2008.
As with the traditional iPod, the iPod Nano charges by being connected to a user's computer. One end of the included USB sync cable plugs into the bottom of the device itself, and the other plugs into a free USB port on the computer. Previous generations of the Nano had the ability to charge via a Firewire port, but that feature has since been dropped with the fourth generation. The Nano currently supports an estimated 24 hours of continuous music playback with a full battery charge.
As with all other models in the Apple iPod line of products, the iPod Nano must be connected to a computer running iTunes to upload music onto the device. A user adds any desired songs to her iTunes library; then, when the Nano is connected to the computer using the included USB cable, iTunes transfers or "syncs" the music onto the device. The iPod Nano currently comes in both an 8GB and a 16GB model.
