GCSE – Lesson 7 – What is the internet?

Curriculum KS4 Unit Lesson

This lesson begins by testing learner recall and asking them to sketch each of the four topologies given. It then moves on to describing the internet from its invention to how it works now. Next, learners discover how a web browser is used to access the WWW by using DNS to find the IP address of each website. At this point, learners use the Packet Tracer software to see a simulation of this, which they can investigate. Finally, learners are given a more in-depth view of how DNS works and the different types of domain servers that are available.
