all about itunes

iTunes is a free application for your Mac or PC. It organizes and plays your digital music and video on your computer. It keeps all your content in sync. And it’s a store on your computer, iPod touch, iPhone, iPad, and Apple TV that has everything you need to be entertained. Anywhere. Anytime.

iTunes lets you enjoy all your music, movies, video, and TV shows on your Mac or PC. When you want to watch or listen to something, you no longer have to look through your CDs or flip through channels — just go to your computer and open iTunes. With your entire media collection in your iTunes library, you can browse everything faster, organize it all more easily, and play anything whenever the mood strikes.

 












How do you get your music and movies from your Mac or PC to your iPhone, iPod, or iPad? iTunes does it for you. How about photos, contacts, and calendars? iTunes transfers them, too. iTunes makes it surprisingly easy to sync media from your computer to your device, and the other way around. Shop the iTunes Store directly from your iPhone, iPod touch, or iPad. You can download music, movies, and TV shows anywhere you are over a Wi-Fi network. When you’re back at your computer, connect your device. iTunes syncs what you bought on the road to your iTunes library. iTunes also wirelessly syncs your iTunes library to your Apple TV, so you can see your movies, listen to your music, and look at your photos on the big screen.
