Real-world networks

In this lesson, students will further develop their understanding of networks. They will look at the three main types of networks, LAN, WAN, and PAN, and at the different topologies that these networks can use in their design. students will carry out an activity in which they will plan a business network to meet the requirements of a fictional company, “Fabgadget Inc.”.
