Edexcel 1CP2 4.1.4: Wired and wireless
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 needs hardware to connect each device, and a way for the bits to travel between them: cables or radio waves. This lesson names the boxes you would find in a school's network cupboard, compares wired with wireless, and builds a model of the switch, the device at the centre of most LANs.
