This document discusses different types of computer networks based on geographical size, including personal area networks (PANs), local area networks (LANs), campus area networks (CANs), metropolitan area networks (MANs), wide area networks (WANs), and wireless local area networks (WLANs). It provides details on each type such as the distance between connected devices, examples of interconnecting equipment, and transmission media used. Review questions at the end test the understanding of common network acronyms like LAN, MAN, and WAN and ask to identify the type of network in different scenarios.
