What term describes a private collection of LANs and WANs that belongs to an organization?

• A. Internet
• B. Extranet
• C. Peer-to-Peer
• D. Intranet

Answer: (D)

A private organizational network that interconnects multiple LANs and WANs to share internal resources is an intranet. It is owned by the organization and kept separate from the public Internet, with access controlled for employees through authentication, firewalls, and VPNs. This setup lets internal sites, file shares, and apps be reachable from company campuses and remote locations while remaining restricted to authorized users.

The public Internet is global and open to anyone. An extranet extends some intranet access to trusted external partners, still under organization-controlled security. A peer-to-peer network describes a sharing model where devices directly exchange resources without a central network server, not a private corporate network.
