The iCloud is an Apple email, storage and data synchronization subscription service that provides 5GB of storage for free. You only get 5 GB for free no matter how many Apple devices you own. Apple also offers 20 GB, 50GB and more to purchase for users. You can purchase more storage online on your Mac in System Preferences or from your iPhone or iPad under iCloud settings.
It can save users’ address book, calendar, notes, Safari bookmarks and photos on Apple’s servers — changes and additions to one Apple device can be pushed to the other registered Apple devices. It requires an Apple ID.
Operating system requirements:
iPhone, iPod touch, or iPad: iOS 5 or later
Mac: OS X Lion 10.7.2 or later
Windows: Windows Vista or Windows 7 with Outlook 2007 or 2010, and the iCloud Control Panel
- A free “@me.com” email address.
- “Find my iPhone,” which lets users opt-in to geo-locate, lock and remote wipe their iPhone, Mac or iPad if it is lost or stolen.
- Photo Stream: a service that can automatically upload and store photos in a device’s camera roll for access from another device.
- Device backups : iPhones and iPads can be automatically backed up to the iCloud mobile service daily when the screen is locked and the device is connected to Wi-Fi and a power source. Backups can also be done manually.
- Download: Purchases from the iTunes store, the iBookstore and the App Store can be saved in a digital locker and can be downloaded to the user’s other Apple devices automatically or manually.
- Save settings: store purchase history settings and data in iCloud so users don’t have to re-enter information on multiple devices.
