Which statement describes a Wide Area Network (WAN)?

• A. Wide Area Network a network that spans a large geographical area.
• B. Local Area Network inside a room.
• C. Wireless Local Area Network for campus.
• D. Virtual Private Network across insecure channels.

Answer: (A)

A Wide Area Network is defined by spanning a large geographical area and linking multiple smaller networks, such as several LANs, over long distances. It uses various transmission methods (leased lines, fiber, satellite, or the public Internet) and is often provided or managed by service providers to connect cities, regions, or countries. This breadth sets it apart from a Local Area Network, which is confined to a building or a single location; a Wireless Local Area Network describes wireless coverage within a campus or facility, and a Virtual Private Network is a secure method for connecting across insecure networks rather than describing the WAN itself. So the statement that describes a WAN is that it spans a large geographical area.
