What intranet use is described in the material?

• A. A network operating within an organization that uses the same TCP/IP protocol used on the Internet
• B. A network on the Internet accessible publicly
• C. A mobile messaging service
• D. A cloud storage service

Answer: (A)

An intranet is a private network inside an organization that uses the same TCP/IP communication protocols as the Internet. This lets internal users access websites, email, file-sharing, and collaboration tools securely within the organization’s firewall, while remaining inaccessible to outsiders. Using standard Internet protocols means familiar technologies (web servers, DNS, authentication) can be employed, but access is controlled through security measures like firewalls and VPNs. The other descriptions describe services that are public, mobile messaging, or cloud storage, not a private internal network.
