What is the term for a collection of different networks that connect and exchange information?

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

Answer: (A)

A global system of interconnected networks that exchange information. This describes the Internet, which links countless networks—home, campus, business, and mobile—using common protocols so data can travel between diverse systems. The Internet isn’t restricted to a single organization like a LAN, private intranets, or restricted extranets; it’s the universal fabric that enables broad, cross-network communication. In contrast, a LAN stays within a limited local area, an intranet is a private internal network, and an extranet extends access to selected external users. Because the description points to a worldwide collection of networks that connect and share information, the term is the Internet.
