Cloud Computing

Definition of Cloud Computing

The term "cloud" comes from early network diagrams, in which the image of a cloud was used to indicate a large network, such as a wide area network (WAN). The cloud eventually became associated with the entire Internet, and the two terms are now used interchangeably. The cloud may also be used to describe specific online services, which are collectively labeled "cloud computing." (Tech Terms)

You probably access the cloud often, if not daily.  To most people who just use their computer for email or web, cloud is just another way to say offsite storage.  This means the data is NOT stored on your computer, but available from a remote location.  With an account, you can access that data like it was sitting on your computer.  And this also gives you the ability to access the same data on different devices, like your computer AND your tablet.  

Accessing the cloud from multiple devices

Social networks are a great example of cloud computing.  And a great place to use two factor authentication!

Other examples of popular clouds:

iCloud is a cloud storage and cloud computing service from Apple Inc. launched on October 12, 2011.  The service also provides the means to wirelessly back up iOS devices directly to iCloud, instead of being reliant on manual backups to a host Mac or Windows computer using iTunes. (iCloud)  

Using any supported web browser, you can use iCloud Drive at
On your Mac, you can go to iCloud Drive in Finder.
On your iPhone, iPad, or iPod touch with iOS 11 or later, you can access your files from the Files app. On iOS 9 or iOS 10, you can access them from the iCloud Drive app.
On your PC with Windows 7 or later and iCloud for Windows, you can go to iCloud Drive in File Explorer.

OneDrive is a Microsoft solution (tied to a Microsoft account) and includes 5GB of file storage free, after which you can pay more if you need more.  To access your OneDrive account, click on File Explorer and then the icon on the left that says "OneDrive."  Sign in with your Microsoft Account and you have access to your files.Google Drive gives you 15GB of storage.  If you have a Gmail account, you have Google Drive.  And of course, if you need more storage, you can buy more from Google.  To access your Google Drive, log into your Gmail account and click on the Google App icon.

DropBox is a hosting service that offers cloud storage, and more.  You can create a special folder on YOUR computer and then the contents of it are synchronized with your DropBox account.  A basic account is free and gives you 2GB of storage.  New computers sometimes come with a DropBox installed.  You would need to install the software to access it. 

Streaming television services accessible at Netflix, Amazon Prime, and YouTube are hosted and powered by online data centers, as are web-based email and social media such as Facebook, Snapchat, Instagram, and Twitter. (It's all about the Cloud)


You will need an account to access these types of clouds. And of course - two factor authentication is HIGHLY encouraged.
