I do not like about the iPod can not play other formats, Ogg Vorbis and FLAC format in particular. MIDI files can be played on iPods as well, but can be converted into a format compatible audio file, select the “Advanced” menu in iTunes.
Apple designed the iPod to work with the iTunes library, which lets you manage your music library on your computer and your iPod. iTunes can automatically synchronize your iPod with specific playlists or with the entire contents of a music library each time you connect your iPod to a central computer.
You can also enter a rating (out of 5 stars) on a song, and can synchronize information of iTunes music library. iTunes does not have the ability to transfer songs from iPod to computer because of legal problems.
However, several third party programs that provide existing facilities of similar music sync to iTunes, but also offer the ability to copy music from iPod to computer. Notable examples include vpod and Winamp iPod plugin for Ml.
iTunes Music Store
The iTunes Music Store (iTMS) is an online music store run by Apple and accessed via iTunes. Was
presented April 28, 2003 and sells individual songs relatively easily and inexpensively (eg, $ 0.99,
At 0.99 euros, 0.79 pounds).
is the only iPod portable music player that can play purchased music, and has this exclusive
helped the store become the dominant online music service.
Purchased audio files use the AAC format with added encryption. Encryption is based on the FairPlay Digital Rights Management (DRM). Up to five authorized computers and an unlimited number of iPods can play.
Burning files to a CD to remove the Digital Rights Management (DRM), whose cost is deducted
the quality of repackaged from a lossy format to another.
iPod can not play music files encrypted with other rival Digital Rights Management (DRM)

Hardware
iPod options was to connect to a user’s computer to update songs or recharge the battery only
Original FireWire. It could also be charged by connecting it to a small power adapter that is included free with many of the first generation of iPod.
Now the standard dock connector was not added until the third generation, in April 2003 when the users
the possibility of using FireWire or USB for data transfer, although the device can no longer be
charged from the USB port and USB cable not included.
Most PCs do not have a FireWire port, this move effectively opened the market for the windows to your iPod, even if the only USB Windows users have been forced to keep FireWire cables to be inserted into the wall adapter.
The dock connector also allows transfer of data, sound, and can go back and iPod accessories, has created a market of explosive devices that have been very profitable for third parties such as Belkin and Griffin. The large number of connecting devices is still a result of the great strengths of the iPod in your competititors.
Features 4-generation iPod could be recovered from the USB version, and eventually Apple began shipping iPods with USB cables instead of one with a FireWire port. Many Macs shipped before 2004 had only USB 1.1, which is a transmission speed of 11 Mbit / s, as opposed to a FireWire 400 and USB 2.0, 480
Although none of these actually transfers on these rates, USB 1.1 is much slower than the other two, and some USB 1.1 may simply be unnecessary to transfer music collections to fill an iPod 40 GB later introductions have continued to reduce reliance on FireWire iPod.
iPod Shuffle, released in January 2005, is connected directly to a USB port and dock connector, and no Firewire support. The iPod Nano was released in September 2005, use the dock connector allowing the FireWire cable can also connect the device to download, but no transmission. With 5-generation iPod, Apple has abandoned all support for FireWire to transfer data to any model of iPod.
Like the Nano, the 5th generation iPod dock connector accepts a FireWire cable, and can be powered by it, but only the USB connection, not the one with FireWire support the transfer of data – a message about this appears on the screen the iPod.
This has drawn criticism from the Mac community since FireWire is standard on Apple Mac computers for many years, while USB 2.0 was added in October 2003.
The first three generations of iPod used two ARM processors running derivatives 7TDMI to 90 MHz, while the newer models are equipped with variable speed chips which operate at a peak of 80 MHz to save battery power.
IPod use 1.8-inch (46 mm) ATA hard drives (with a proprietary connector) from Toshiba and the iPod Mini uses a compact flash thumb drives from Hitachi Microdrive. It has a chip 32 MiB flash ROM that contains a boot loader, a program that tells the device to load the operating system to another medium (in this case, the hard drive).
All iPods, except the 60 GB 5th generation version has 32 MB of RAM, a part of maintaining OS loaded from firmware, and the vast majority, which serves to cache songs loaded from disk.
For example, you could turn the iPod’s hard drive once and copy approximately 30 MB of songs in a playlist in RAM, thus saving the power not to have the pan for each track. (The 60 GB fifth-generation iPod has 64 MB of RAM, to extend the battery life.)
the iPod was originally introduced to the screen in black and white, but not the current model uses one. iPod Photo (in addition to the functionality of the fourth generation of iPod was released in late 2004) has presented a color display, iPod shuffle (published January 2005) there is no evidence.
When the iPod mini was replaced by the iPod Nano got a color screen (and photo Capabilty) and 5th generation iPods with color displays unique, size and capacity of the photograph.
