Which network type connects devices over a wide geographical area, such as a country or region?

• A. LAN
• B. WLAN
• C. MAN
• D. WAN

Answer: (D)

A wide-area network is built to connect devices and networks that are spread over large distances, such as cities or countries. It links multiple local networks (like offices or campuses) so they can communicate and share resources across long gaps, often using carrier lines, leased connections, or the Internet. This scale sets WAN apart from other types: a local area network stays within a small area like a building or campus; a wireless local area network is just a wireless version of that small-area network; and a metropolitan area network covers a city or metro area—not hundreds or thousands of miles apart. So the description fits a WAN, which is designed to span large geographic regions.
