What term describes a network that connects networks over geographical distances?

• A. Intranet
• B. Extranet
• C. Local Area Network
• D. WAN

Answer: (D)

A Wide Area Network (WAN) is the type that links together networks over large geographic distances. It interconnects multiple smaller networks such as LANs, campuses, or data centers, using various communication links (leased lines, fiber, MPLS, VPNs, satellite) so data can travel across cities, countries, or continents. The Internet is the largest example of a WAN. A Local Area Network stays confined to a small area like a building or campus, with high-speed connections and typically under a single organization’s control. An intranet is a private network within an organization, often built over LANs or WANs, but its defining feature is restricted access rather than distance. An extranet extends access from an intranet to external users (like partners) while maintaining privacy and control, which again focuses on access rather than the broad geographic reach.
