What do I need to download audio and video tracks that are in the UA on iTunes U?
You need a computer with an Internet connection and Apple’s free iTunes software. iTunes runs on very well on both Windows and Macs and can be downloaded from Apple’s website. Note that it is not a Web browser; it is a big software application that runs on the Internet. You do not need to buy anything from Apple to use iTunes. You do not need an iPod because you can play the audio and video on your computer.
