When you save a photo, document, or school project to the “cloud,” it doesn’t float in the sky — it travels to powerful computers called servers. These servers are stored in huge data centres around the world, managed by companies like Google, Microsoft, or Amazon.
Every time you upload something to the cloud, the data is broken into digital code and sent across secure internet connections. It’s then copied to multiple servers so that even if one fails, your files remain safe elsewhere. This process is called redundancy.
Cloud systems also use encryption — a kind of digital lock that scrambles your information so only you (and those you allow) can access it. When you log in, the system verifies your identity before unlocking your data.
The cloud makes sharing and storage easy — you can access your work from any device, anytime. But it also teaches an important lesson: convenience comes with responsibility. Using strong passwords and keeping accounts private ensures your “digital backpack” stays secure in the endless sky of information.
