Data Centre Basics: What is a Data Centre?
An explanation for children
Have you ever wondered what happens when you click on a video, send a message, or play an online game? Where does all that information go?
Imagine a giant toy box, but instead of storing toys, it stores everything digital: your photos, videos, games, music, and files.
This magical place is called a data centre. In this article, we’ll answer the question, “what is a data centre?”, we’ll find out what they look like inside, and why they’re so important in our everyday lives.
Get ready to dive into the world behind the screens!

How do data centres work?
Data centres are very big buildings (sometimes bigger than a football pitch!) that hold special computers called servers. Servers are where the internet lives. They’re really powerful and work together to make sure that when you want to watch a video or play a game, everything works quickly and smoothly. They also keep information safe so that nothing gets lost.
Servers get stacked on top of each other in big cupboards called racks. Every data centre has thousands of these racks, all lined up in rows.
Servers in racks get very hot and need to be cooled down. So, every server in a data centre has lots of fans to make sure it keeps cool.
Why do we need data centres?
Without data centres, you wouldn’t be able to video call your Nan, play video games with your friends, or do your online maths homework. Everything from watching the weather forecast to buying your mum a Mother’s Day present involves data centres in one way or another.
Entertainment
Data centres are super important for anything digital. This means the video games you play, social media apps you scroll, videos you watch, messages you send, photos you store on your phone, and the music you listen to. Without data centres, home assistants like Siri and Alexa wouldn’t work!
Online learning
Without data centres, teachers would not be able to give their lessons online. They would also not be able to set homework online (you might think this is a good thing!), or have online ‘classrooms’ like Google Classroom.
Shopping
Online shopping needs data centres to store and process information about products, process payments for items, and to handle questions from customers. Without data centres, you wouldn’t be able to buy anything from online stores like Amazon, eBay, or Apple.
Transportation
GPS apps like Apple Maps and Waze use data to give people real-time directions and traffic information. Also, airlines and airports rely on data centres to handle the information for booking flights and tracking planes. Without data centres, transportation would be very different!
Weather forecasts
Scientists who specialise in predicting the weather use data centres to store and process weather data from all over the world, helping them to predict whether it’s going to rain or not.
Vital services
Doctors and nurses use data about patients and their medical history to look after them when they’re ill. Researchers also use data stored in data centres to find treatments and cures for diseases, and to make medicine more accessible for those who need it. Policemen use data about criminals to keep our streets safe, and firemen use it so they can quickly respond to fires.
Data center or data centre?
Data center and data centre are two different spellings of the same thing. Both mean a building containing servers that hold and process the world’s data. Data ‘center’ uses the American English spelling and data ‘centre’ uses the British English spelling.
So, if you live in the US, you’ll probably see the spelling ‘data center’ (or if you live in South America, Saudia Arabia, Indonesia, Japan, or the Philippines, where US spelling is also common). If you live in Europe, Canada, or Australia you’ll probably see the spelling ‘data centre’.
Data centres are like the hidden engines of the digital world, working hard behind the scenes to make sure we can enjoy our favourite games, connect with friends and family, learn new things, and even help doctors take care of patients.
They store and protect the endless stream of information we rely on every day. Next time you see an ambulance, send a message, or buy something online, remember the amazing data centres that make it all possible. With their powerful servers and cool technology, they’re keeping our digital world running smoothly!
