Networks and topologies — Note 8 of 10

What you need to know

Cloud computing refers to using remote servers over the Internet to store files, run software, and provide services — instead of using local hardware. Data and programs can be accessed from anywhere with an Internet connection.

What to know

Advantages: accessible from anywhere with Internet, no need to manage or upgrade local hardware, automatic backups.
Disadvantages: requires an Internet connection, data stored on third-party servers may be less secure, ongoing subscription costs, less control over data.

Key terms

Exam tipCommon mistake

The Cloud: Remote servers accessed over the Internet used to store data, run software, and provide services.
Exam tip: Cloud questions often ask for advantages AND disadvantages — always give a balanced answer covering both sides.
Common mistake: Saying the cloud 'is not stored anywhere'. Cloud data IS stored on physical servers — they are just in remote data centres, not on your local device.
Exam tip: Cloud advantage/disadvantage questions often require CONTEXTUALISATION — apply to the scenario for full marks. E.g. 'lawyers can access case files from court' not just 'can access from anywhere'.
