What is the cloud?

You may have heard people using terms like the cloud, cloud computing, or cloud storage. But what exactly is the cloud?

Simply put, the cloud is the Internet—more specifically, it's all of the things you can access remotely over the Internet. When something is in the cloud, it means it's stored on Internet servers instead of your computer's hard drive.

Why use the cloud?

Some of the main reasons to use the cloud are convenience and reliability. For example, if you've ever used a web-based email service, such as Gmail or Yahoo! Mail, you've already used the cloud. All of the emails in a web-based service are stored on servers rather than on your computer's hard drive. This means you can access your email from any computer with an Internet connection. It also means you'll be able to recover your emails if something happens to your computer.
