Edexcel 1CP2 4.1.1: Why networks
The free BugBot lesson that teach this point, a robot to try it on, and the past-paper questions that test it.
What it covers
A network is two or more devices connected so they can share data. Your school's computers are a network, your phone joins one every time it connects to Wi-Fi, and the robots on the BugBot mat are a network too: every message one robot sends, the others receive. This module is about how networks work, from a single room to the whole internet.

- LAN, WAN and PAN
- Client-server and peer-to-peer
- Who is on the network?
Or do it in the simulator, with tasks that mark themselves
