Networks and the Internet | Year 7 Computing PowerPoint Lesson

Give Year 7 pupils a genuinely solid grip on how the internet works with this colourful, visual, ready-to-teach PowerPoint lesson. It covers networks, the client-server model, why data is broken into packets, how packet switching routes them across the internet, and how IP addresses, domain names and DNS all fit together. Clear analogies — a packet as a labelled envelope, a router as a decision-maker — make abstract ideas concrete, and a dedicated slide untangles the internet, the web, Wi-Fi and “the cloud”, which pupils constantly mix up. Two interactive, hands-on activities bring it to life: a packet-relay game using cut-up paper strips, and a paired activity tracing every step of a real web request. A misconceptions slide and built-in teacher prompts on every slide make this non-specialist friendly and ideal as a cover lesson, while the stretch slide connects today’s vocabulary directly to GCSE Computer Science topics like network topologies and bandwidth calculations. Just project and teach — no extra preparation needed. A matching cover image is included.
