# Real-world networks

In this lesson, we will further develop our understanding of networks. We 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.We will carry out an activity in which we will plan a business network to meet the requirements of a fictional company, Fabgadget Inc.
