Which statement describes the largest network in existence?

• A. A LAN
• B. The Internet
• C. A WAN
• D. A PAN

Answer: (B)

Think about networks by how big their reach is. A LAN is confined to a single building or campus, so its scope is local. A PAN is even narrower, just around a person or a few nearby devices. A WAN covers a larger geographic area, linking multiple sites, but it’s still a defined network often owned or operated by an organization. The Internet stands apart because it’s a global system of interconnected networks that links countless private, public, academic, and government networks around the world, all using common protocols. Because it connects networks across continents and oceans, it’s larger than any individual LAN, PAN, or WAN.
