Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
Since the whole point of iCloud is that all your stuff should be on all your devices, it wouldn’t make much sense if the contents of your iTunes Library didn’t make it to the iCloud party. Happily, almost any music you have in one place can now appear anywhere you want.
Using a feature called iTunes in the Cloud, you can share your purchased iTunes items with up to ten of your (and perhaps your family’s) iOS devices and computers. New items you purchase from the iTunes Store automatically appear on all your devices; there’s no more need for manual syncing.
You can also purchase a subscription to a service called iTunes Match, which scans your iTunes Library for music tracks you didn’t purchase from the iTunes Store. Matched files are replaced by streaming versions from the Store, at full quality. Any tracks that can’t be matched are uploaded from your computer to iCloud and can be downloaded to all your devices.
