iTunes

iTunes is Apple's music and video management software. It also serves as a desktop client for the iTunes Store and handles iPod/iPhone synchronization.

It consists of 3 major components: iTunes itself, QuickTime and Apple Mobile Device Support (AMDS). QuickTime is used for audio/video playback and encoding, while AMDS is the component responsible for synchronizing with iPhone/iPod Touch.
