This chapter introduces networks and their basic components. It discusses intermediary network devices that allow communication across networks like routers, switches and bridges. It also defines the main types of networks including local area networks (LANs) that connect devices within a small geographic area like a home or office, and wide area networks (WANs) that connect multiple LANs together over a larger geographic distance. The chapter then provides more details on local area networks, their topologies and examples.
