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.

Statements A, B and C are correct descriptions of HTTP, FTP and SMTP, whereas statement D is clearly wrong. TCP/IP is a suite of communication protocols used for data transmission over networks, not for offline storage on a hard disk. It provides the foundation for Internet and many network operations. Hence, the combination that selects only statement D as wrong is the correct answer.

Option A:
Option A is incorrect because it treats both A and D as wrong statements. Statement A correctly explains that HTTP is used for transferring web pages and related resources. Including a true statement in the wrong set makes this option invalid.

Option B:
Option B is incorrect because it groups C and D as wrong statements. While D is wrong, C is correct in describing SMTP as a protocol for sending email between servers. Mixing a correct statement with an incorrect one means this option cannot be the right answer.

Option C:
Option C is incorrect because it contains A, B and D as wrong statements. Both A and B are accurate descriptions of HTTP and FTP, so they should not be labelled wrong. Including true statements in the wrong set contradicts the actual meanings of the protocols.

Option D:
Option D is correct because it isolates D as the only wrong statement. It recognises that TCP/IP is used for network communication rather than offline storage. By acknowledging A, B and C as correct, this option matches the intention of the question.
