What describes a Wide Area Network (WAN)?

• A. Nearby computers are on the same network
• B. Computers on the same network are long distances from each other
• C. Computers communicate through a wired connection
• D. Info that authorized people can access

Answer: (B)

A Wide Area Network describes networks that cover large geographic areas, connecting multiple local networks so computers can communicate across cities, countries, or continents. This broad reach is what sets WANs apart from smaller networks, like a LAN that stays within a building or campus. Since WANs can be wired or wireless and rely on various transmission links (including the Internet), the key idea is the distance and scope of the network, not the specific media used or who is allowed to access data. Therefore, the description that emphasizes computers being far apart best matches a WAN. The other descriptions refer to proximity within a single network, the medium being wired, or access control, none of which define WANs.
