What is an intranet?

• A. Intranet - A network operating within an organization that employs the same TCP/IP protocol used on the Internet
• B. A public network on the Internet
• C. A wireless sensor network
• D. A satellite broadcast system

Answer: (A)

An intranet is a private network used inside an organization. It runs on the same Internet protocols (TCP/IP) that the global Internet uses, which lets employees access internal websites, document repositories, and business applications from within a controlled environment. Access is restricted to authorized users, typically guarded by firewalls and login requirements, and remote access can be provided safely through VPNs. This combination of private use and familiar Internet technology is what defines an intranet.

That matches the description of a network operating within an organization that employs the same TCP/IP protocol as the Internet. In contrast, a public network on the Internet is accessible to the world, a wireless sensor network focuses on sensor data collection and may have different networking needs, and a satellite broadcast system is designed for wide-area distribution rather than a private internal network.
