What Is Cloud Computing?
Cloud computing means using computing resources such as storage, software, and processing power over the internet instead of relying only on your own device.
Instead of buying and maintaining powerful servers yourself, you connect to professionally managed computers located in secure data centres around the world.
Cloud Computing Is Like Electricity
💡 Think of it like this
You don't own a power plant—you simply use electricity when you need it. Cloud computing works the same way. You use computing resources when you need them without owning the infrastructure.
What's the Difference?
💻 Local Storage
Files stay on your device.
☁️ Cloud Storage
Files are securely stored online and available from multiple devices.
The Cloud Isn't a Place
☁️ Remember This
The cloud is simply someone else's professionally managed computer.
What to Remember
- Cloud computing uses the internet to deliver computing services.
- Your files are stored in secure data centres.
- Most modern apps rely on cloud technology.
- Cloud services make collaboration easier.
