Intranet internal organisation network – UGC NET Question

An intranet employs web technologies such as browsers and servers within a restricted environment to share internal documents, announcements and applications. It is protected from external access by authentication mechanisms and firewalls. Because it is internal to the organisation, it is called an intranet. Therefore, intranet correctly fills the blank.

Option A:
Option A, internet, denotes the global network of interconnected public networks and is open to general users rather than limited to a single organisation.

Option B:
Option B is correct because intranet is the accepted term for private networks that use internet technologies within organisational boundaries.

Option C:
Option C, extranet, allows limited external access to certain resources for partners or clients, which is beyond the purely internal network described.

Option D:
Option D, darknet, refers to intentionally hidden networks or services that operate over the internet and is associated with anonymity, not normal organisational information sharing.
