What is apple iCloud and how does it work? (Explained 2021)

iCloud is one of Apple’s most interesting products – what is iCloud, and what does iCloud do? How do I set up my iCloud account and use all its features? In this article, we’ll explain what you need to know about using iCloud and how to make the most of its many services and features.

What is iCloud?

iCloud is nothing more than a cloud storage service provided and developed by Apple Inc. and introduced on 12… October 2011. In 2018, the service had about 850 million users, up from 782 million in 2016.

What is cloud storage?

A file hosting service, a cloud storage service, an online file storage provider, or a cyberblocker is an internet hosting service specifically designed to host users’ files. Allows users to download files from the Internet after providing a username and password or other form of authentication. In short, this storage is based on a cloud server, not a local server. This means you don’t take up any storage space on a specific device, and you can access your information from any device connected to the internet.

What does iCloud do?

The Apple iCloud lets you store and sync photos, documents, movies, music and more. From re-downloading apps and games to watching TV shows and movies, you can find all your iCloud content on any Apple device with the same Apple ID.

For example, the contacts: If you give permission, iCloud syncs the contacts across all your iOS and macOS devices. This means you only have to maintain one contact list, because any changes you make on iPhone are applied to the contacts on your Mac and other devices. It also works with your calendar, iCloud storage, notes, and iWork.

What is iCloud Drive?

iCloud Drive is a place to find documents that don’t belong anywhere else in the iCloud. This is the place for Word documents, PDFs, screenshots, and anything else not already synced with iCloud. It works like third-party storage services, such as Google Drive or Dropbox.

iCloud is it useful?

Here are a few reasons why iCloud can be useful!

  • With iCloud, users can store data like documents, photos, and music on remote servers and download them to iOS, MacOS, or Windows devices. In addition, iCloud allows you to share and send data with other users and manage your Apple devices in case of loss or theft.
  • iCloud also provides the ability to wirelessly back up data from iOS devices directly into iCloud, rather than using iTunes to manually back up to a Mac or Windows host computer. Users of the service can also instantly share photos, music and games by connecting their accounts wirelessly to AirDrop.
  • iCloud replaced Apple’s MobileMe service as the data synchronization center for email, contacts, calendars, bookmarks, notes, reminders (task lists), iWork documents, photos, and other data.

How much does iCloud storage cost?

No matter how many iOS or macOS devices you have, Apple only offers iCloud users 5GB of free storage – a paltry amount when you consider what the competition has to offer.

There’s not much room. If you need more – and if you plan to back up multiple devices to the cloud or store larger collections of photos, videos or documents off- device – you’ll need to spend a little more.

Find out how much it costs to upgrade your iCloud storage space here:

Apple offers four storage options: 5GB (free); 50GB (99 cents per month); 200GB ($2.99 per month); and 2TB ($9.99 per month).

How much do you use for storage?

It’s easy to see how much iCloud storage space you’re using.

  • In iOS: Press the top pane (Apple ID) of the preferences. Then press iCloud. You should see a graph showing the usage of iCloud storage. Press Manage Storage to go to a page with a list of each item that stores data in iCloud (you’ll also see how much data each item uses).

  • In the Macos: Go to System Preferences>iCloud and select Manage… in the lower right corner of the window.
