clouds and icloud

1. What is a cloud ?

The Cloud , in computing, is the Internet or a piece of the Internet.

Think of the internet is the sky and the cloud is the cloud, a piece of sky. Each cloud provide a different service.

Examples:

• The Gmail cloud delivers us our mail.

• The Dropbox cloud stores our files.

• The iCloud cloud stores our photos and videos, and more.


2. What is icloud ?

The iCloud is the generic name for all of the services Apple delivers to us through the Internet , whether that's on a Mac, iPhone, or a PC running Windows.

iCloud is the name of Apple's cloud-based or Internet-based services.

The icloud's services include:

• iCloud Drive,
which is similar to Dropbox and Google Drive,

• iCloud Photo Library,
which is an offshoot of Photo Stream,

• iTunes Match
and even

• Apple Music.

iCloud also provides us with a way to back up our iPad in case we need to restore it at a future point.

We can download the iWork suite to our iPad from the App Store. iWork is an office suite of applications of Apple.

We can also run Pages, Numbers, and Keynote on our laptop or desktop PCs through icloud.com .


How Can I Use It ?

1. iCloud Backup and Restore

Apple provides 5 GB of free iCloud storage for Apple ID account, which is the account you use to login to the App Store and buy apps. This storage can be used for many purposes including storing photos, and backing up your iPad.

By default, every time you plug your iPad into a wall outlet or a computer to charge it, the iPad will attempt to back itself up to iCloud.

You can also manually initiate a backup by opening the Settings app and navigating to iCloud --> Backup --> Back Up Now.

You can restore from a backup by following the procedure to reset your iPad to factory default and then choosing to restore from the backup during the setup process of the iPad.

2. Find My Device

Another important feature of iCloud is the Find My iPhone/iPad/MacBook service. Not only can you use this feature to track down the whereabouts of your iPad or iPhone, you can use it to lock down the iPad if it is lost or even remotely reset it to factory default, which erases all data on the iPad.

While it can sound creepy to have your iPad tracked wherever it travels, it also combines with putting a passcode lock on your iPad to make it quite secure.

3. iCloud Drive

iCloud Drive It is a service that allows apps to store documents on the Internet, which allows you to access those files from multiple devices.

In this way, you can create a Numbers spreadsheet on your iPad, access it from your iPhone, pull it up on your Mac to make edits and even use your Windows-based PC to modify it by signing into iCloud.com.

4. iCloud Photo Library,
Shared Photo Albums, and
My Photo Stream.

• My Photo Stream is a service that uploads every picture taken to the cloud and downloads it onto every other device signed up for My Photo Stream.

This can make for awkward situations, especially if you don't want every photo uploaded to the Internet.

It also means if you take a picture of a product in a store so you can remember the brand name or model number, that picture will find its way onto every other device.

Still, the feature can be a life-saver for those who want the photos taken on their iPhone to transfer to their iPad without doing any work.

• iCloud Photo Library is the new version of Photo Stream. The big difference is that it actually uploads the photos to iCloud permanently , so you don't have to worry about the maximum number of photos.

You also have the ability to download the entire image on your device or an optimized version that doesn't take up as much storage space.

Unfortunately, iCloud Photo Library isn't part of iCloud Drive .
