UGC NET Questions (Paper – 1)

In non-positional systems such as Roman numerals, symbols have fixed values that do not change with position. The total value is obtained by combining these fixed-value symbols using certain rules rather than place weights. Such systems are therefore termed non-positional.

Option A:
Option A accurately describes systems where there is no concept of positional weights tied to powers of a base. The symbol's meaning is fixed and does not depend on place value.

Option B:
Option B, positional, describes systems like decimal and binary where the position of a digit is critical in determining its contribution. This is the opposite of what the question describes.

Option C:
Option C, weighted, is associated with positional systems in which each position carries a specific weight, again contradicting the description.

Option D:
Option D, mixed-radix, refers to systems where different positions may have different bases, as in time representation (hours, minutes, seconds), and is not solely about position independence.

Statement C is the only wrong statement because privacy and ethical issues are central concerns in learning analytics. Statements A, B and D correctly describe the purpose, examples and use of analytics in feedback and improvement. Collecting and interpreting student data must always be accompanied by safeguards, consent and ethical guidelines. Therefore, the option that identifies only C as wrong best matches the realities of big data and learning analytics in education.

Option A:
Option A is incorrect because it groups A and C together as wrong statements. Statement A is a standard definition of learning analytics, which aims to enhance teaching and learning by using learner data. Including this true statement among the wrong ones shows a misunderstanding of the concept.

Option B:
Option B is correct because it isolates C as the only incorrect statement and acknowledges that A, B and D are sound descriptions. It reflects the fact that learning analytics does raise privacy concerns and that these need careful management. By focusing solely on the wrong statement, it satisfies the requirement of the question.

Option C:
Option C is incorrect because it labels both B and C as wrong. B is actually correct since LMS clickstream data, scores and engagement metrics are typical components of educational big data. Mixing a true statement with a false one makes this combination invalid.

Option D:
Option D is incorrect because it treats A, B and C as wrong statements. Both A and B are accurate explanations of learning analytics and big data, and only C misrepresents the ethical dimension. This option incorrectly classifies true statements as wrong and therefore cannot be chosen.

Read Only Memory is used to store firmware such as the system BIOS that must be available whenever the computer starts. Its contents remain intact even when power is removed, making it non volatile. Because it is usually not modified during normal operation, it is considered more stable than RAM. Thus, the appropriate term is ROM.

Option A:
Option A, cache, is a small, fast memory that may be volatile and is designed for temporarily holding frequently used data, not permanent firmware.

Option B:
Option B, RAM, is volatile and loses data when power is lost, so it cannot be relied upon for essential startup routines.

Option C:
Option C is correct because ROM is the standard type of memory used for permanent, non volatile storage of firmware in computer systems.

Option D:
Option D, register, refers to very small, fast storage locations within the CPU used during computation rather than for long term firmware storage.

Inclusive education seeks to ensure that learners with diverse abilities and needs can participate meaningfully in mainstream classrooms. ICT-based assistive technologies remove barriers by presenting content in alternative formats such as audio, Braille or subtitles. This aligns with the goal of inclusion rather than separation. Hence the tools described in the stem serve inclusive education.

Option A:
Option A is correct because international conventions and educational policies define inclusive education as adapting environments and resources so that all learners are accommodated. Assistive ICT devices are central to this adaptation.

Option B:
Option B, punitive, suggests punishment and is entirely opposed to the supportive philosophy behind assistive technologies. Such tools are designed to empower, not discipline, learners.

Option C:
Option C, competitive, may occur within educational settings but does not specifically relate to addressing disability or access barriers.

Option D:
Option D, segregated, implies educating learners with disabilities in separate institutions, whereas the technologies in the stem help integrate them into regular classrooms.

Statements A, B and D correctly represent key features of flipped classrooms, whereas statement C is incorrect. In the flipped model, students engage with content before class and then use class time for active learning supported by ICT tools. Collaborative work is often encouraged, rather than prohibited, so C misrepresents the pedagogy. Therefore, the combination A, B and D only is the correct set of statements.

Option A:
Option A is incomplete because it recognises pre-class content and active classroom use but omits the role of ICT platforms described in D. Without acknowledging video platforms and LMS, the picture of flipped classrooms is partial.

Option B:
Option B is incorrect because it includes C along with A and B as correct. Statement C conflicts with the collaborative and interactive nature of flipped classrooms; students frequently work together in class on higher-order tasks. Accepting this statement makes the combination invalid.

Option C:
Option C includes B and D only and omits A, even though A defines the fundamental idea of shifting content delivery to before class. Without A, the explanation of the flipped model is incomplete, so this option cannot be accepted.

Option D:
Option D is correct because it brings together A, B and D, which collectively capture pre-class engagement, in-class active learning and the supporting role of ICT. By excluding C, it avoids the misconception that flipped classrooms reject collaboration.

Statements A, B and D correctly describe the functions and benefits of MIS in educational settings, while statement C is false. MIS integrates data from multiple subsystems, provides dashboards for key indicators and supports planning and evaluation. It clearly goes beyond storing paper records in cupboards, which is what C wrongly implies. Therefore, the combination A, B and D only is correct.

Option A:
Option A is incomplete because it recognises integration and decision-making but omits the planning and evaluation support mentioned in D. Without D, the description does not fully cover the strategic uses of MIS.

Option B:
Option B is incorrect because it includes A, B and C as correct and thereby accepts C. Statement C confuses MIS with purely manual storage and fails to recognise its digital processing role. Including this false statement invalidates the combination.

Option C:
Option C is incorrect because it lists B and D only, leaving out A. Integration of data from admissions, examinations and finance is a key reason institutions adopt MIS, so omitting A produces an incomplete account.

Option D:
Option D is correct because it groups A, B and D, the three true statements about MIS capabilities, and excludes C, which mischaracterises MIS as non-digital. It offers a coherent view of MIS supporting data-driven administration.

Statements A, B, C and E highlight pedagogical and access-related advantages of virtual labs. They can safely model complex or hazardous experiments, offer repeated practice, need alignment with objectives and extend opportunities to remote learners. Statement D is false because many disciplines still require hands-on work to develop psychomotor skills. Statement F is false because technical support and infrastructure such as bandwidth and compatible devices are critical for effective use, so the correct set includes A, B, C and E only.

Option A:
Option A is incomplete because it omits E and therefore does not address the equity aspect of reaching remote learners. While A, B and C are correct, they do not fully capture how virtual labs widen access, so this option is partial.

Option B:
Option B is incorrect because it includes D, which overstates the ability of virtual labs to replace physical practice entirely. Even with strong simulations, disciplines like medicine and engineering still require real-world practice, so D cannot be accepted.

Option C:
Option C is correct because it integrates safety, practice, alignment and access advantages without claiming that real labs or infrastructure planning are unnecessary. It therefore matches both pedagogical and practical perspectives on virtual labs.

Option D:
Option D is incorrect because it includes F and omits A. Accepting F denies the importance of infrastructure and support, which are vital to reliability. Leaving out A also overlooks the core reason for using virtual labs in high-risk or costly experiments.

Statements A, B, C and E are widely recommended practices in online video design, while D and F undermine quality. Short segments, interactive quizzes, supplementary materials and clear outcomes all enhance clarity and engagement. Poor audio hinders comprehension, and banning visual aids would remove important channels for explanation. Hence, the correct set of statements is A, B, C and E only.

Option A:
Option A is incomplete because it excludes E, thereby not recognising the importance of clarifying learning outcomes at the start. Without E, the answer misses a key element of purposeful instructional design.

Option B:
Option B is incomplete because it omits B, so it does not acknowledge the role of in-video questions in fostering active learning. Engagement is central to effective online teaching, so leaving out B weakens the combination.

Option C:
Option C is incomplete because it excludes A, which addresses the need to manage attention span by chunking content. Without A, the temporal aspect of design is not appropriately represented.

Option D:
Option D is correct because it captures multiple complementary practices—segmenting, interactivity, supplementary resources and clear goals—while rejecting D’s and F’s tolerance of poor audio and absence of visuals. This option aligns with established multimedia learning guidelines.

Big data refers to datasets characterised by high volume, velocity and variety that require advanced analytical tools for meaningful interpretation. In education, learning management systems and online platforms generate big data about learner behaviour and performance. Analysing such data can inform institutional decision making and personalised learning. Therefore, the term that fits the description is big data.

Option A:
Option A is correct because big data is the recognised label for large scale, complex data environments that go beyond the capacity of conventional processing tools.

Option B:
Option B, metadata, describes data about data, such as file properties, and does not necessarily imply large scale or complexity.

Option C:
Option C, spam, refers to unsolicited or irrelevant messages, especially in email, and is not a neutral term for extensive datasets.

Option D:
Option D, cache, is a small, fast memory used to store frequently accessed data, the opposite of large complex datasets.

Statements A, B, C, E and F identify major environmental concerns and mitigation strategies related to ICT, while D is clearly false. Energy-hungry data centres and toxic e-waste are genuine problems, but power management, repair, reuse and green procurement can reduce impacts. Ignoring environmental considerations in infrastructure planning would conflict with sustainability goals. Therefore the correct set consists of A, B, C, E and F.

Option A:
Option A is correct because it brings together the main issues of energy use and e-waste with practical strategies for reduction. It also incorporates procurement policies and device-level power management, offering a comprehensive view of ICT and environment.

Option B:
Option B is incorrect because it omits F, thus missing the role of procurement policies in environmental responsibility. A, B, C and E are true, but ignoring equipment selection leaves out an important institutional lever.

Option C:
Option C is incorrect because it omits A and leaves out the specific mention of data centre energy use. While B, C, E and F are true, excluding A means an important dimension of ICT environmental impact is missing.

Option D:
Option D is incorrect because it omits B and therefore does not explicitly reference hazardous e-waste. A, C, E and F are correct, but leaving out B underplays the toxicity issue central to many ICT-environment discussions.

Statement D is the only wrong statement because cybercrimes can and often do occur over networks without any physical theft of computers. Hacking, identity theft and phishing frequently exploit vulnerabilities and human behaviour online. Statements A, B and C correctly describe common types of cybercrime. Therefore, the option that selects only D as wrong is correct.

Option A:
Option A is incorrect because it lists A and D as wrong statements. Statement A is true, as hacking does involve unauthorised access to systems or networks. Including this correct definition in the wrong set undermines the accuracy of the option.

Option B:
Option B is incorrect because it groups C and D as wrong statements. While D is wrong, C correctly explains that phishing tricks users into disclosing sensitive information. Mixing a true statement with a false one disqualifies the combination.

Option C:
Option C is incorrect because it combines A, B and D as wrong statements. Statements A and B are accurate descriptions of hacking and identity theft and should not be treated as wrong. Only D is incorrect, so this option misclassifies important concepts.

Option D:
Option D is correct because it isolates D as the sole wrong statement. It acknowledges that cybercrimes can occur entirely online and are not limited to physical theft of devices. Recognising A, B and C as correct descriptions of cybercrime types makes this option consistent with ICT security understanding.

Blended learning deliberately integrates face to face sessions with online components to optimise learning outcomes. Students may attend physical classes and also participate in virtual discussions or complete digital assignments. This approach seeks to leverage the strengths of both environments. Therefore, the appropriate term is blended learning.

Option A:
Option A is correct because blended learning is widely defined in educational technology literature as the combination of traditional and online instructional methods.

Option B:
Option B, distance, learning typically occurs entirely away from campus and may not involve regular face to face sessions.

Option C:
Option C, correspondence, learning is associated with print based materials sent by post, which predates modern ICT based online learning.

Option D:
Option D, remedial, learning focuses on addressing specific learning gaps and does not necessarily involve any mixture of delivery modes.

Decimal 0.375 equals 3/8. In binary, the fraction 1/4 is 0.01₂ and 1/8 is 0.001₂, so 3/8 is 1/4 + 1/8. The binary sum of 0.01₂ and 0.001₂ gives 0.011₂. Therefore, 0.011₂ is the exact binary representation of 0.375.

Option A:
Option A is correct because it has ones in the 2^-2 and 2^-3 positions, giving 1/4 + 1/8 = 3/8. This matches the decimal fraction exactly.

Option B:
Option B, 0.001₂, represents 1/8 or 0.125 in decimal, which is too small compared to 0.375. It lacks the 1/4 component.

Option C:
Option C, 0.01₂, equals 1/4 or 0.25 in decimal, still smaller than 0.375. It accounts for only one of the required fractional parts.

Option D:
Option D, 0.111₂, equals 1/2 + 1/4 + 1/8 = 7/8 or 0.875 in decimal, which is much larger than 0.375.

The operating system mediates interactions between users and hardware by providing a user-friendly environment and standardised services. Users issue commands via graphical or command interfaces, and the OS translates these into low-level hardware instructions. It shields users from the complexity of device management and memory handling. Hence it functions as an interface between the user and the hardware.

Option A:
Option A, a compiler, translates high-level programming code into machine code but does not manage overall user interaction with the system. It is a development tool that itself runs under the operating system. Therefore it cannot be regarded as the primary interface.

Option B:
Option B, network protocol, specifies rules for communication between networked devices. Protocols operate at communication layers and are implemented within or above the OS, but they are not themselves the general interface for all user–hardware interaction.

Option C:
Option C, firewall, is a security component controlling network traffic and is often implemented as part of system software. However, it plays a protective role rather than providing a broad user interface to all hardware resources.

Option D:
Option D is correct because the OS presents menus, windows and commands that allow users to control programs and hardware without dealing directly with low-level details. This intermediary role is accurately summarised as acting as an interface.

Data backup involves copying files or databases to secondary storage so that information can be restored after hardware failure, accidental deletion or other disasters. Regular backups are essential for organisational resilience. ICT policies usually specify backup schedules and methods. Hence, the practice described is data backup.

Option A:
Option A is correct because backup specifically denotes maintaining extra copies of data for recovery purposes.

Option B:
Option B, formatting, prepares a storage medium for use and usually erases existing data, which is the opposite of preservation.

Option C:
Option C, deletion, removes data and increases risk of loss rather than protection.

Option D:
Option D, fragmentation, refers to data being scattered on a disk, which may affect performance but is unrelated to safety copies.
