A Wide Area Network (WAN) spans a large geographic area, such as cities, states, or even countries. The Internet is the largest WAN, as it connects computers all around the world. While a LAN connects devices within a relatively small and localized group, such as a home or office, and a campus network serves a specific area like a university or corporate campus, they are both more localized than a WAN. A router, which connects networks, and a modem, which connects to an Internet Service Provider, do not by themselves constitute networks.
