IPod+Nano-Chromatic

Purpose
The general purpose of this device is to allow the user to be able to listen to music of their choice in a simpler way rather than sorting through CDs, or constantly changing channels on the radio. You can download your favorite bands to be available at your leisure, watch that episode of the soapopera that you missed last week or store the movies that are most memorable to you. You're even able to keep pictures of friends, family, pets, celebrities, locations, etc. in it. It proves to be quite useful and space efficient.

Energy
Like the iPod Nano, the Nano-Chromatic uses both battery-produced energy as well as electrical energy. While the battery-produced energy is used to keep the iPod functioning in order to allow the user to utilize the device until it needs to be charged once more, the electrical energy is used to act upon commands made by your finger. Metal pieces beneath the cover of the click wheel serve as the conductor to electic currents, while the cover itself serves as an insulator to protect your finger from receiving shock. All the while, the current builds beneath the insulator. With the accelerometer, the silicon springs measure the position of the silicon mass by using the electrical current. When the iPod gets rotated it causes a variation in the electrical currents passing through the silicon springs. This variation then sends signals to the iPod telling it to adjust the game or whatever is being rotated.

Controls
One of the essential sensors featured in not only the iPod Nano-Chromatic, but in all iPods would be the [|click wheel]. The click wheel reacts when the pad of your finger touches and/or slides along it due to sensors located directly beneath it which then sends a current to the wheel itself. A newly introduced feature of the iPod Nano-Chromatic is called the accelerometer, which works by using three elements: a silicon mass, a set of silicon springs, and an electrical current.

Materials
There are numerous things that are very important in order to get the full advantage of the iPod. Some of those things would be headphones, a USB cable to connect your music device to your computer, iTunes, and the [|display screen] itself. Without the use of headphones, there would be no way to listen to the music, videos, or movies stored on the device, unless you use something such as an iHome or some form of speakers compatible with an iPod. If you do not have a USB cable, then you won't be able to place music, videos, or movies onto you iPod, which would render it useless. The USB cable also serves as a charger, so it stands as an essential when it comes to an iPod in general. Lastly, if iTunes is not downloaded onto your computer, there is no other way to download music, videos, or movies onto your iPod because the material specifically needs to be stored in this free program. If there was no display screen, it would be much more difficult to find the right song, and you would not be able to put videos, pictures, or movies on your iPod. There is an iPod available like that called the iPod Shuffle, but it has proved to be quite a nuisance to navigate.

__How does the Hard Drive works?__
A hard drive is a computer component that holds data. Every computer needs at least one hard drive  to store its operating system programs and user information. This drive  is usually internal, however, as computer systems have evolved and different needs, threats, and circumstances have arisen, the additional external  hard drive  has become extremely popular. It made from aluminum. The tape inside is bonded to the hard drive. The tape is made from Iron oxide (FeO) and Ferric oxide (Fe2O3).

Science
The hard drive (CPU) stores music, videos, movies, games, notes, pictures, dates and time, etc., while the Apple click wheel's sensors use your fingers as a conductor to send an electrical current through, which will then trigger the command made. The accelerometer gives the user the ability to adjust the screen to portrait or landscape, as well as turns on shuffle if you shake hard.

Design
It is available in nine different colors consisting of silver, black, purple, blue, green, yellow, orange, red, and pink. It's made of all aluminum and glass, and has a noticeable feature of a curved body. It is considered the most "enviornmentally friendly ipod" because of its arsenic-free glass, as well as a few other exclusions in the design.



Evolution
It is the fourth generation iPod Nano, and has come quite the way. It's been modified to be thinner, to allow the user to watch videos on it, an accelerometer has been added to allow the user to turn on the shuffle feature by shaking the iPod, and gives an option between portrait and landscape display by tilting the iPod to the left or right. It has also been designed to hold more audio, graphics, and videos than its siblings, with a newly designed user-interface which includes a voice recorder that starts automatically when an Apple compatible microphone is connected to the device. The Quiz game that is usually featured on the iPod has been dropped and replaced with the new Maze game, and the "Genuis" feature has been introduced, which automatically creates playlists based on a algorithm built by the Apple company.
