A WAN that uses a common addressing and transfer protocol suite called Transfer Control Protocol/Internet Protocol is called a(n) ________.

A WAN that uses a common addressing and transfer protocol suite called Transfer Control Protocol/Internet Protocol is called a(n) ________.

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

Answer: (A)

The key idea is that TCP/IP is the global protocol suite that underpins the Internet. The Internet is a worldwide system of interconnected networks that use IP addressing to route packets and TCP to provide reliable communication, spanning many different networks over wide areas. An intranet, while it may run TCP/IP, is a private network inside an organization and not the public, globally connected network. An extranet extends access to partners but remains private, and a LAN is a local network, not a wide-area network. So the correct description is that the WAN using TCP/IP is the Internet.
