This Computing scheme of work video supports teachers in explaining how websites work and what happens when a web address is typed into a browser. It prepares teachers to guide pupils in understanding the hidden systems behind everyday Internet use.

The video demonstrates how a user’s request is sent from a device to a server, which stores all the elements of a website including images, text and code. The server responds by sending this information back to the user’s device, where the browser assembles the page. The concept of the cloud is also explained, showing how data stored on servers around the world can be accessed from any Internet-connected device. Teachers are supported in leading the accompanying unplugged activity, where pupils role-play the different parts of a network to make the process more tangible.
