Which statement is true about LANs in comparison to WANs?

• A. LANs cover a large geographic area
• B. WANs are used to connect devices within a building
• C. LANs typically cover a small geographic area
• D. WANs are faster than LANs

Answer: (C)

Local Area Networks are built for a small geographic area, such as a single building or campus. This limited scope is matched by high-speed, low-latency connections like Ethernet and Wi‑Fi, which is why LANs typically cover a small geographic area. Wide Area Networks, on the other hand, connect separate LANs over much larger distances—between buildings, cities, or countries—often using slower or shared links and more complex routing. So the statement that LANs typically cover a small geographic area is true, while the other descriptions mix up where LANs and WANs operate or how fast they are.
