What type of network covers large geographical areas?

The type of network that covers large geographical areas is a Wide Area Network (WAN). WANs are designed to span broad geographic regions, often connecting multiple local area networks (LANs) or metropolitan area networks (MANs) across cities, countries, or even continents. This capability allows businesses and organizations to facilitate communication and data transfer over significant distances, using various technologies such as leased telecommunication lines, satellites, and internet connections.

In contrast, Local Area Networks (LANs) and Wireless Local Area Networks (WLANs) are typically limited to smaller areas, such as a single building or a campus. A LAN often connects devices in close proximity, while a WLAN provides a wireless connection within a similar limited range. Metropolitan Area Networks (MANs) cover larger areas than LANs but are still confined to a single city or metropolitan area, making them suitable for connecting multiple LANs within a city but not suitable for covering extensive geographic areas like WANs do.
