Syncing is a must for anyone who owns Apple devices, because it's what allows you to move seamlessly from one device to another. You can sync files, media, apps, and other information. All you have to do is set up iCloud on each device; then you can access the same content from almost anywhere.
Introduction to iCloud
iCloud is a service provided by Apple that lets you store your music, TV shows, and other files in the cloud (in other words, online). It also automatically syncs your files and information on all of your devices, so each one stays up-to-date.
iCloud works with Mac computers and Windows PCs. It also works with iOS devices like the iPad, iPad Mini, iPhone, and iPod Touch. With iCloud, you no longer need to connect your devices to your computer to sync your files and settings; everything will sync automatically over Wi-Fi.
When you sign up for iCloud, you get 5GB (gigabytes) of storage space for free. If you want, you can buy additional space for an annual fee. Your music, TV shows, and photos won't count toward the 5GB limit, so you may not need to buy additional space.
With iCloud, as well as other cloud-based services, you may have heard about something called push technology. This simply means the content is downloaded automatically (or pushed) when syncing with other apps and devices. iCloud uses a lot of push technology, which helps to keep everything convenient and simple for users.
