Intranet versus Internet – UGC NET Question

An intranet uses the same basic protocols and tools as the public Internet, such as web servers and browsers. However, it is logically separated and access is restricted to members of a particular organisation. This allows internal communication, document sharing and collaboration in a controlled environment. Thus, a private network using Internet technologies for authorised users is the correct description.

Option A:
This option describes the Internet itself, not an intranet. The Internet spans the globe and is not limited to a single organisation or access group.

Option B:
A printed handbook containing Internet addresses is just a static list of URLs. It is not a network and cannot provide interactive communication or services, so it does not qualify as an intranet.

Option C:
This option correctly distinguishes scope and accessibility by emphasising both the use of Internet technologies and the restriction to authorised internal users. It reflects how institutions create secure internal portals and services.

Option D:
A satellite is a physical communication device that may carry many different kinds of traffic, but by itself it does not define a logical private network like an intranet. An intranet is defined by how computers are networked and controlled, not by a particular satellite.
