UGC NET Questions (Paper – 1)

A Local Area Network interconnects computers and other devices within a relatively small physical area, typically using high speed links. Organisations use LANs to share resources such as printers, files and internet connections. The limited scope allows for easier management and lower latency. Therefore, the network described in the question is a LAN.

Option A:
Option A, MAN, or Metropolitan Area Network, spans a city or large campus and covers a wider geographic area than that mentioned in the stem.

Option B:
Option B, WAN, or Wide Area Network, extends over large regions or countries and connects multiple LANs, which goes beyond the constraints of a single building or campus.

Option C:
Option C, PAN, or Personal Area Network, is focused on very short range communication around an individual, such as connections between a phone and a headset.

Option D:
Option D is correct because LAN is the standard term used in ICT to refer to networks confined to small areas like offices, schools or laboratories.

The digital divide highlights disparities in access to devices, connectivity and digital skills across social groups or regions. These differences can reinforce existing inequalities in education, employment and civic participation. Policymakers emphasise closing the digital divide as part of inclusive development strategies. Therefore, the inequality described in the stem is termed the digital divide.

Option A:
Option A is correct because the phrase digital divide is widely used in ICT and social policy discourse to describe unequal access and use, distinguishing information-rich and information-poor groups.

Option B:
Option B, euphoria gap, is not a recognised concept in ICT studies and does not capture structural disparities in access.

Option C:
Option C, software loop, suggests a programming construct rather than a social phenomenon.

Option D:
Option D, bandwidth ring, could refer to a network topology or capacity but does not describe the broader socio-economic gap mentioned in the question.

Screen time refers to the duration for which individuals are engaged with devices such as computers, tablets and smartphones. High screen time is associated with health concerns including eye fatigue, poor posture and sedentary behaviour. Educators discuss balancing ICT use with offline activities to promote wellbeing. Hence, the phrase high screen time describes the problem.

Option A:
Option A is correct because screen time is the established expression in health and education debates about prolonged device use.

Option B:
Option B, reaction, time denotes how quickly someone responds to a stimulus and is not about prolonged exposure to screens.

Option C:
Option C, response, time typically measures system or user speed, not the total time spent using devices.

Option D:
Option D, backup, time refers to the duration of copying data and has no relation to health concerns of ICT use.

IPv6 was introduced to provide a vastly larger address space than IPv4, and it does this by using 128 bit addresses. These are typically written as eight groups of hexadecimal numbers separated by colons. The large number of possible addresses supports future growth of the internet and new types of devices. Hence, the blank should be filled with 128 bits.

Option A:
Option A, 32, repeats the IPv4 length and would not solve the problem of limited address space, which is the key motivation for IPv6.

Option B:
Option B is correct because formal specifications state that IPv6 addresses are 128 bits long, enabling an enormous number of unique identifiers.

Option C:
Option C, 64, would increase the address space but is not the standard length defined for IPv6.

Option D:
Option D, 256, is larger than necessary and does not match the protocol definition used in practice.

Statements A, B, C and D correctly describe Wi-Fi, Bluetooth, cellular data and wireless security. Wi-Fi and Bluetooth are radio-based technologies, cellular networks provide mobile Internet and encryption protocols such as WPA2 enhance wireless security. Statement E is false because wireless signals can be intercepted and require protection, and F is false since disabling wireless can save battery and reduce attack surface. Thus the correct combination includes A, B, C and D only.

Option A:
Option A is incorrect because it omits D and therefore ignores the importance of encryption for securing Wi-Fi data. While A, B and C are true, they do not include the crucial aspect of wireless security.

Option B:
Option B is incorrect because it adds E, which wrongly claims that interception is impossible and security is irrelevant. Including this false statement makes the entire combination invalid.

Option C:
Option C is incorrect because it omits A and does not acknowledge Wi-Fi as a widespread wireless LAN technology. Although B, C and D are true, leaving out A means the set does not capture the full picture.

Option D:
Option D is correct because it recognises the main wireless technologies and emphasises the role of encryption. It excludes unrealistic claims about interception and power usage, aligning with sound understanding of wireless networking.

An ISP operates the communication infrastructure that links end users to the global Internet. It allocates IP addresses, offers bandwidth plans and routes data packets between customer devices and external networks. Without an ISP or equivalent service, most individuals and campuses could not access web resources, email or other online applications. Hence, the central function is provision of Internet connectivity.

Option A:
Curriculum design and examination planning are academic policy tasks handled by bodies such as universities and regulatory agencies, not by ISPs. While educational institutions may consult ISPs for network needs, core academic functions remain separate.

Option B:
Manufacturing hardware is the domain of electronics companies. An ISP might purchase equipment from them but does not primarily produce devices like CPUs and monitors.

Option C:
Grading examination scripts requires academic judgement, which ISPs are not responsible for. Their role is in network provision, not educational assessment.

Option D:
This option correctly identifies that ISPs act as gateways between users and the wider networked world. They may also offer services like email or cloud storage, but these are built on the foundational service of providing access.

Statements A, B and C correctly define star, bus and ring topologies as described in networking theory. They specify how nodes connect to hubs, backbones and loops. Statement D is false because some topologies, especially star, can have single points of failure at central devices. Therefore the correct combination is A, B and C only.

Option A:
Option A is incorrect because it lists only A and B as correct and leaves out C. While A and B are true, C is also correct in describing a ring structure. Excluding C produces an incomplete summary of topologies.

Option B:
Option B is incorrect because it suggests A, C and D are correct, thereby accepting D. Statement D contradicts the idea of a central hub or shared cable that can cause widespread disruption if it fails.

Option C:
Option C is incorrect because it groups B and C only and omits A. Since star topology is one of the most common designs, an explanation that leaves it out is inadequate.

Option D:
Option D is correct because it brings together A, B and C as true and excludes D, which overlooks the possibility of single points of failure. This matches standard discussions of network design.

IPv4 stands for Internet Protocol version 4 and uses a 32 bit addressing scheme. These bits are often represented as four decimal octets separated by dots, such as 192.168.0.1. The 32 bit structure limits the total number of unique addresses that can be assigned. Therefore, the blank in the stem should be filled with 32 bits.

Option A:
Option A is correct because standard networking texts describe IPv4 addresses as 32 bit numbers, which is the basis for the dotted decimal notation commonly seen. This length explains the eventual exhaustion of IPv4 address space.

Option B:
Option B, 64, corresponds to some internal addressing schemes but not to the globally defined size of IPv4 addresses.

Option C:
Option C, 128, is associated with IPv6, the newer version of the protocol that expands the address space, not IPv4.

Option D:
Option D, 16, would allow far too few addresses to support modern networking and has never been the standard size for IP addressing.

Blended learning strategically integrates traditional classroom sessions with online components such as forums, digital resources and assessments. This combination aims to exploit the strengths of both modalities, offering flexibility and richer interactions. When designed well, blended courses can enhance learner engagement and outcomes. Therefore, the approach described is blended learning.

Option A:
Option A is correct because the term blended learning is widely used in educational technology literature to denote precisely this mix of online and face-to-face experiences.

Option B:
Option B, isolated, would suggest separation rather than integration and does not convey the intentional combination of modes.

Option C:
Option C, rote, focuses on memorisation-based learning methods and is not tied to mode of delivery.

Option D:
Option D, unilateral, implies one-sided communication, which conflicts with the interactive nature of blended environments.

Statements A, B, C and E provide an accurate picture of ICT-based distance education. LMSs host content, asynchronous tools support flexible participation, synchronous tools enable live interaction and support services assist learners. Statement D is false because distance courses often mix flexible and scheduled activities, and F is false since self-regulation is crucial in online environments. Thus the correct combination is A, B, C and E only.

Option A:
Option A is correct because it acknowledges platforms, communication modes and support structures that characterise distance education. It excludes unrealistic requirements for daily synchronous access and the claim that self-regulation is unnecessary.

Option B:
Option B is incomplete because it omits E and therefore fails to mention the importance of digital libraries and helpdesks. Even though A, B and C are true, they do not cover all support aspects.

Option C:
Option C is incorrect because it includes F, which understates the need for learner self-management. Mixing an incorrect statement with B and C makes the combination invalid.

Option D:
Option D is incomplete because it leaves out B and so does not discuss asynchronous participation, which is a hallmark of distance education. A, C and E alone do not represent all correct statements.

Distance learning involves planned teaching activities conducted with learners who are not physically present in the same place as the teacher. ICT tools such as learning management systems, video lectures and discussion forums enable communication and content delivery across distances. This allows flexible access to education for diverse learners. Thus, the mode described in the stem is distance learning.

Option A:
Option A, face to face, assumes that teachers and learners are co-located in the same physical classroom, which contradicts the geographical separation emphasised.

Option B:
Option B is correct because ICT-supported courses that reach learners beyond campus boundaries are routinely classified as open and distance learning in higher education policies.

Option C:
Option C, remedial, refers to support for learners who need additional help and can be offered either face to face or at a distance; it is not defined by geographical separation.

Option D:
Option D, incidental, learning occurs informally and unintentionally and is not a structured mode of delivery using ICT tools.

In base-4, the first digit after the point has weight 4⁻¹ = 1/4, so 0.3₄ = 3×(1/4) = 3/4 = 0.75.

Option A:
Option A correctly uses fractional place weight 1/4 and multiplies by 3 to get 0.75.

Option B:
Option B would match 0.2₄.

Option C:
Option C would match 0.1₄.

Option D:
Option D does not equal 3/4 and is not the value of 0.3₄.

Statements A, B and D accurately depict how ICT supports the research process, whereas statement C is false. Reference managers, online databases and data analysis tools help researchers at different stages, but they do not replace ethical responsibilities. Plagiarism rules remain applicable regardless of the technology used. Consequently, the combination containing A, B and D but excluding C is correct.

Option A:
Option A is incorrect because it mentions only A and B and omits D. While A and B are true, statement D is also correct in recognising the role of data analysis software in research. Leaving out D makes the answer incomplete.

Option B:
Option B is correct because it selects A, B and D, the three statements that show ICT’s contribution to literature access, reference management and data analysis. It excludes the wrong claim in C that ethics are no longer necessary, which contradicts basic research principles.

Option C:
Option C is incorrect because it includes C, which asserts that ethical norms are unnecessary. Even though B and D are true, the presence of C means the option endorses unethical behaviour, making it unacceptable.

Option D:
Option D is incorrect because it treats all four statements as correct and therefore accepts C. Since C is clearly at odds with research ethics, this combination cannot be the right answer.

“Digital divide” is a socio-economic term that points to inequalities in access to devices, connectivity, skills, and meaningful ICT use. It highlights how some groups benefit from ICT while others are left out.

Option A:
This option correctly frames the divide as a gap in effective ICT access and use across individuals and groups.

Option B:
This is a technical distinction between signal types, not a social issue about unequal access.

Option C:
ICT is used in both urban and rural areas to varying degrees; confining ICT to cities oversimplifies and misstates the problem.

Option D:
E-books vs printed books is about formats; the core of digital divide is inequality of access and capability, not just media formats.

Statements A, B, C and E describe advanced uses and features of MOOCs, including verified certification, analytics-based insights, credit integration and global peer interaction. Statement D is false because many MOOCs run in scheduled cohorts with fixed start and end dates. Statement F is false since MOOC platforms host a wide range of disciplines beyond computer science, so these two must be excluded. The remaining statements A, B, C and E therefore form the correct combination.

Option A:
Option A is incomplete because it excludes E, missing the important social dimension provided by discussion forums. While A, B and C are true, they underrepresent the collaborative learning opportunities central to many MOOCs. Thus this option does not include all correct statements.

Option B:
Option B is incorrect because it adds D, which wrongly claims that MOOCs are never cohort-based. Numerous courses are designed with specific schedules, so including D introduces a clear inaccuracy.

Option C:
Option C is correct because it captures certification, analytics, credit use and peer interaction as complementary aspects of institutional engagement with MOOCs. It filters out D and F, which oversimplify pacing models and subject coverage.

Option D:
Option D is incorrect because it includes F and omits A. Leaving out A ignores the role of proctored exams in verified certificates, and accepting F wrongly limits MOOCs to a single field. This combination therefore cannot be accepted.
