If you are asking the question what is the iPod, it is a portable media player created by Apple. The first model was released in November 2001, and there are currently four versions available: the hard drive-based iPod classic, the touch screen iPod touch, the compact iPod Nano and the ultra-compact iPod shuffle.
Overview of iPod Features
Like most digital music players, these devices can function as an external data storage device. The capacity varies depending on the model, with the iPod shuffle having a capacity of 2 GB and the Classic 160 GB. While it is a music player, you can use it to store other files. You can use iTunes to transfer calendars, Web bookmarks, e-mail settings, contact information, games, videos, photos and music to these devices from your computer. The media player capabilities are the same as those of the iPhone and iPad, but they are different products.
Software and Support
This music player can play many audio files including MP3, Apple Lossless, Audible audiobook, WAV, AIFF, Protected AAC and AAC/M4A. It is also capable of displaying PNG, TIFF, GIF, BMP and JPG. The 5th and 6th generation iPod Classic and the 3rd generation Nano can also play QuickTime and MPEG-4 (H.264/MPEG-4 AVC) video formats.
The music player used to be available only for the Mac OS but beginning with the second generation began supporting Windows. The iPod does not have native support for WMA. However, the Windows version has a converter for WMA without Digital Rights Management (DRM). There is no native support for MIDI files, but it can be changed into a supported file.
The music player has color displays with anti-aliasing text and graphics with animations. Every iPod except the iPod Touch, the 6th generation iPod Nano, and the 3rd generation iPod Shuffle, have 5 buttons. The newer models’ buttons are joined to the click wheel. This design was implemented to give it a cleaner interface.
The buttons allow you to go to the previous track, next track, pause and play. The 3rd generation iPod controls are not on the player, but on the earphone cable. There is one button for playing and pausing, and buttons for controlling the volume.
The iPod Touch doesn’t have a click wheel but has a touch screen with a sleep/wake button and a home button. The 2nd and 3rd generation iPod Touch have buttons for controlling the volume.
These music players have become very popular, which is why there are many accessories available for them. Some of the accessories are made by Apple but others are developed by vendors. Some of the most popular accessories are audio/visual cables for TV connections, wired remote controls, FM radio tuners and sound recorders. Other available accessories are wireless earphone, screen films, protective case, wireless remote controls and external speakers.
Every iPod except the iPod Touch can work in disk mode that is, used for storing data files. Most music players can access files when you copy them using standard copying applications. However, an iPod requires you to use software specifically made for transferring files to the device. Because of this, most people use iTunes to transfer the files. However, there are now many alternative programs available.
If you are studying what is the iPod, remember that media files transferred in the device are kept in a hidden folder. The proprietary database file is also kept there.
