Edexcel 1CP2 4.1.8: Topologies
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 topology is the layout of a network: which devices are joined to which. The layout decides what happens when a cable breaks or a device fails, how much cable is needed, and how data gets from one place to another. This lesson compares the four topologies on the exam, and finds routes through a mesh of robots.
- Four topologies
- Routes through a mesh
Or do it in the simulator, with tasks that mark themselves
Lessons that teach it
