UGC NET Questions (Paper – 1)

The internet is often described as a network of networks because it interconnects diverse networks worldwide using the TCP/IP protocol suite. It enables services such as the World Wide Web, email and file transfer. This global connectivity supports communication, commerce and education on an unprecedented scale. Hence the system described in the stem is the internet.

Option A:
Option A, intranet, refers to a private network within an organisation that may or may not be connected to the wider internet and does not span all sectors and countries.

Option B:
Option B is correct because definitions of the internet explicitly mention its global scope and use of standard protocols to interlink heterogeneous networks. The wide range of participating entities listed in the stem matches the actual composition of the internet.

Option C:
Option C, local area network, is restricted to a small geographic area such as a campus or office building and cannot be equated with the worldwide structure.

Option D:
Option D, personal area network, covers connections among devices close to an individual, such as Bluetooth accessories, and is far smaller in scale than the network described.
