Networks and the Internet
Pupils explore how computers connect to each other to form networks and how the global internet functions.
TL;DR:Networks and the internet are the nervous system of the modern world. For 6th Year students, this topic explains how computers 'talk' to each other across the room or across the globe. This aligns with the SESE Geography Curriculum (Human Environments) and the Digital Learning Framework. Students learn about routers, servers, and the invisible paths that data takes, including the role of IP addresses as 'digital home addresses.'
About This Topic
Networks and the internet are the nervous system of the modern world. For 6th Year students, this topic explains how computers 'talk' to each other across the room or across the globe. This aligns with the SESE Geography Curriculum (Human Environments) and the Digital Learning Framework. Students learn about routers, servers, and the invisible paths that data takes, including the role of IP addresses as 'digital home addresses.'
In Ireland, we can connect this to our history of communication, from the first transatlantic telegraph cable in Valentia Island to the modern data centres that dot our landscape. Understanding that the internet is a physical network of cables and computers, not just a 'cloud,' is a key learning outcome. This topic empowers students to understand the infrastructure that supports their digital lives.
This topic benefits from hands-on, student-centered approaches where students can physically map out and simulate the flow of data across a network.
Key Questions
- What is a computer network?
- How does information travel across the internet?
- What is an IP address?
Watch Out for These Misconceptions
Common MisconceptionThe 'Cloud' is literally in the sky.
What to Teach Instead
Many students think data is stored in the atmosphere. Use a gallery walk of data centre photos to show that the 'cloud' is actually thousands of powerful computers in big buildings, often right here in Ireland.
Common MisconceptionWi-Fi and the Internet are the same thing.
What to Teach Instead
Explain that Wi-Fi is just the 'invisible cable' that connects your device to the router. Use a physical simulation to show that you can have Wi-Fi (a local network) without being connected to the global internet.

The Packet Race
Students act as 'packets' of data (parts of a photo). They must travel from a 'Sender' to a 'Receiver' through a maze of 'Routers' (other students). If a path is blocked, the routers must find a new way to get the packet home.
Inquiry Circle
Mapping the School Network
In small groups, students go on a 'Network Hunt' around the school to find routers, Wi-Fi access points, and Ethernet ports. They then draw a map showing how they think the school's computers are connected.
Think-Pair-Share
The World Without Internet
Students discuss with a partner how their daily life would change if the internet disappeared for a week. They must identify three things that would be harder and one thing that might be better, then share with the class.
