What is the correct term for Internet-like networks deployed within an enterprise and accessible only to authorized internal users?

Introduction / Context:
Organizations often build private networks that use the same technologies as the public Internet—web servers, browsers, TCP/IP—but restrict access to employees. Recognizing the correct term for such private, internal deployments is a basic networking and IT management concept.

Given Data / Assumptions:

• The network uses Internet technologies (HTTP, TCP/IP, web apps).
• Access is limited to members of a single enterprise.
• Public access is not permitted.

Concept / Approach:
An intranet is a private network that employs Internet standards and technologies for internal use. By contrast, an extranet extends certain intranet services to external partners via controlled access. The other listed phrases are either generic or irrelevant to this context.

Step-by-Step Solution:

Verification / Alternative check:
Company portals, internal HR systems, and internal knowledge bases accessible only behind a corporate firewall exemplify intranets.

Why Other Options Are Wrong:

• Extranets: Involve outside organizations with controlled access.
• Inter organizational networks: Too broad and not the standard term here.
• Switching alternating: Nonsensical in this context.

Common Pitfalls:
Confusing intranets with extranets or with VPNs; a VPN is a secure tunnel that may provide access to an intranet, but it is not itself the intranet.

Final Answer:
Intranets
