What does the term 'cloud computing' refer to?
Cloud computing is storing and managing data in remote servers hosted on the internet.

Advantages
By using cloud computing, data stored on the cloud can be accessed from any device in any location, and can provide a cheap and reliable backup in case files store by tradition means are lost or corrupted.

Disadvantages
The main disadvantage of cloud computing is that files and data stored in the cloud can only be accessed when connected to the internet, rendering files inaccessible if not connected.

There is also the danger of data security, as it is stored in a remote location where security is mostly out of your control.
