The cloud is useful because it is convenient and reliable. For example, if you use Gmail or Yahoo! Mail, your emails are stored on Internet servers. This lets you check your email from any device with an Internet connection. It also keeps your emails safe if your computer stops working.

Here are some common uses of the cloud:

• File Storage – You can store files, emails, and other data in the cloud. This allows you to access them from any device. Examples: Google Drive, Dropbox.
  
  
  
• File Sharing – You can share files easily with many people at the same time. Examples: Flickr, iCloud Photos.
  
  
  
• Data Backup – Cloud services can automatically save your files. This protects your data if your computer is lost or damaged. Example: Carbonite.
