Which statement best describes an intranet?

• A. A network operating within an organization that uses the same TCP/IP protocol used on the Internet
• B. A public network outside the organization
• C. A wireless local area network
• D. A global corporate network using satellite links

Answer: (A)

An intranet is a private network used inside an organization to share information, collaborate, and run internal applications. It uses the same TCP/IP protocols as the Internet, so internal websites, email, databases, and tools can work in a familiar way while access is restricted to authorized users. Security is a key aspect, typically implemented with firewalls, authentication, and sometimes VPN access for remote workers. This combination of being internal and using Internet-style protocols differentiates it from a public network (the Internet) and from other network types like a wireless LAN or a global satellite-based WAN, which describe specific technologies rather than the private scope and purpose of an intranet.
