What term refers to a system of interconnected networks?

• A. Intranet
• B. Internet
• C. Extranet
• D. LAN

Answer: (B)

The Internet. A system of interconnected networks is exactly what the Internet is—a global network that links countless private, public, academic, business, and government networks so they can communicate using shared protocols like TCP/IP. That broad, inter-network connectivity is what sets the Internet apart from other options.

A LAN is a local area network confined to a small area like a building or campus, not a global system. An intranet is a private network inside an organization, typically not reachable from the broader Internet. An extranet extends that private network to certain external partners, still not the worldwide interconnection described by a system of interconnected networks.
