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.

Starting with version 9, iTunes on Windows includes Apple Application Support component, which is basically WebKit. It is used to display the updated iTunes Store as well as iTunes LPs and iTunes Extras.
