How does iCloud work?

iCloud is storage space on Apple servers which are located in one of a number of huge data centres in the US. When you create an AppleID account, you’re automatically allocated 5GB of space in iCloud.  Once you’re logged in, you can access the storage space, and use all the features that need files stored there, including third party applications, and features like Universal Clipboard.

How to set up iCloud

Your iCloud account is based on your Apple ID. So if you haven’t got an Apple ID already, you’ll need to create one. You may also have to update the OS on your device. Your next step depends on what device you’re using.

On iPad or iPhone: Partway through the setup process for an iPhone or iPad, iOS will ask if you want to use iCloud. If you didn’t activate it during setup, you can later go to Settings, tap your name at the top (or tap to sign in), select iCloud, then enter your Apple ID and password.

On Mac: Open System Preferences and click iCloud. Now sign in with your Apple ID and tick the services you want to use.

On Apple TV (fourth-gen or 4K): If you didn’t choose to activate iCloud (by entering your Apple ID) when you first set up, go to Settings > Accounts > iCloud, then select Sign In.

On PC: Download and install iCloud for Windows. Open it and sign in with your Apple ID, then put a tick next to the iCloud services you want to use.
