UGC NET Questions (Paper – 1)

Malware, short for malicious software, encompasses any program designed to infiltrate, damage or disable computer systems without the user's informed consent. Viruses, worms, Trojans, ransomware and spyware are all types of malware. Recognising malware as a broad category helps users understand that threats come in many forms. Hence, the harmful programs described in the stem are collectively malware.

Option A:
Option A, freeware, refers to software distributed without charge and is not inherently harmful; many reputable applications are freeware.

Option B:
Option B is correct because cybersecurity literature clearly defines malware as an umbrella term for hostile or intrusive software, and the examples listed in the question are standard subclasses.

Option C:
Option C, open source tools, emphasises licensing and code availability rather than malicious intent, so it does not fit the description.

Option D:
Option D, device drivers, are important system components that allow the operating system to communicate with hardware and are not necessarily malicious.

Bandwidth or data transfer rate on digital networks is usually measured as the number of bits transmitted per second. For broadband connections, speeds are often advertised in megabits per second, indicating millions of bits sent each second. Hence, Mbps is the most appropriate unit here.

Option A:
Kilogram is a unit of mass used for measuring physical weight, not digital data flow, so it is irrelevant to Internet speed.

Option B:
This option correctly identifies Mbps as the common unit for specifying Internet speeds in ICT contexts, reflecting that data is transmitted as bits and large volumes are expressed in kilobits and megabits per second.

Option C:
Hertz is a unit of frequency indicating cycles per second, used for CPU clock speeds or signal frequency, not for user-level data transfer rates.

Option D:
Litre per minute measures liquid flow such as water and has nothing to do with the rate of electronic data transmission.

A digital signature uses asymmetric cryptography to bind a person's identity to a digital document through a unique key pair. Verification processes confirm that the document originated from the claimed sender and has not been altered in transit. In many countries, digital signatures have legal validity for e-governance and e-commerce transactions. Hence, the cryptographic authentication method described is a digital signature.

Option A:
Option A, digital watermark, embeds information into media for ownership identification but does not necessarily authenticate the sender in formal transactions.

Option B:
Option B is correct because ICT security frameworks explicitly define digital signatures as providing authenticity, integrity and non-repudiation, aligning with the functions listed in the stem.

Option C:
Option C, simple password, offers only basic authentication and does not involve cryptographic binding of identity to a specific document.

Option D:
Option D, captcha code, distinguishes human users from automated bots but does not certify document origin or integrity.

Statements A, B, C, D and F offer a comprehensive view of knowledge management. Systems can store explicit documents, communities of practice exchange tacit know-how, metadata and tagging support retrieval, culture influences sharing and taxonomies/folksonomies are structures for organising resources. Statement E is false because documents should be reviewed and updated over time to remain accurate. Therefore all statements except E are correct, and the right combination is A, B, C, D and F.

Option A:
Option A is incorrect because it omits F and does not mention classification approaches, which are important for organising knowledge repositories. A, B, C and D are true but not exhaustive.

Option B:
Option B is incorrect because it leaves out B and thus ignores communities of practice as a channel for tacit knowledge sharing. A, C, D and F are correct, yet the combination is incomplete.

Option C:
Option C is correct because it includes all substantive elements of knowledge management while rejecting the notion that stored documents never need revision. It emphasises both technical and human dimensions of managing knowledge.

Option D:
Option D is incorrect because it includes E, which claims documents never need updating. This contradicts the principle of keeping knowledge current, so the presence of E makes the option wrong.

Statements A, C and D accurately portray core elements of digital citizenship, whereas B conflicts with ethical conduct. Responsible digital citizens act ethically, protect privacy and make informed choices about platforms. Anonymity does not justify harmful behaviour, so B must be excluded from the correct set. Hence, the combination A, C and D only is correct.

Option A:
Option A is correct because it selects exactly those statements that reflect responsible and informed digital behaviour and leaves out B, which normalises cyberbullying. It aligns with ICT education goals of promoting safe and respectful online participation.

Option B:
Option B is incomplete because it includes A and C but omits D. Understanding terms and privacy policies is also an important digital citizenship competence, so leaving out D gives an incomplete picture.

Option C:
Option C is incorrect because it groups B and C and treats both as correct. C is true but B condones hurtful anonymous comments, contradicting ethical norms, so this option wrongly accepts a harmful practice.

Option D:
Option D is incorrect because it treats all four statements as correct and thereby accepts B. Since digital citizenship explicitly rejects abusive behaviour, this combination is not acceptable.

Statements A, B and C correctly describe the public, private and hybrid deployment models in cloud computing, while D misrepresents the idea of community cloud. Public cloud is shared among many customers, private cloud belongs to one organisation and hybrid cloud combines both types. Community clouds are shared by several organisations with common concerns, not by a single individual user. Therefore, the combination that includes A, B and C but excludes D is the only fully correct option.

Option A:
Option A is correct because it recognises that statements A, B and C all align with standard definitions of cloud deployment models. It also implicitly rejects statement D, which wrongly claims that community cloud serves a single individual instead of a group of organisations. By covering the three major models without including the incorrect description, this option gives a complete and accurate picture.

Option B:
Option B is incorrect because it leaves out statement C about hybrid cloud. While A and B are true, excluding C ignores the important model where organisations mix public and private resources. Since the question asks for all correct statements, this incomplete combination cannot be accepted.

Option C:
Option C is incorrect because it includes statement D and omits A and C. Although B is true, D is wrong in limiting community cloud to an individual user. The absence of A and C further weakens this option, so it does not represent the full set of correct statements.

Option D:
Option D is incorrect because it accepts all four statements, thereby treating D as correct. Including D means accepting a false description of community cloud, and this invalidates the entire combination even though A, B and C are accurate.

Open access journals use the Internet to make research outputs widely available without subscription barriers for readers. Many apply licences that permit sharing and sometimes adaptation as long as attribution rules are followed. This model supports faster dissemination and greater visibility of research, especially in resource-constrained settings. Therefore, the option highlighting free online access with licence conditions captures the essence of open access.

Option A:
This option correctly reflects that open access concerns reader-side availability, not necessarily production cost. It emphasises that ICT infrastructure underpins such journals by hosting and delivering content globally.

Option B:
Option B describes traditional print-only access, which can limit readership and does not utilise ICT for wide distribution.

Option C:
Option C describes a closed, high-cost model that is the opposite of open access. Access barriers here are financial and institutional.

Option D:
Option D focuses on advertisements and lacks scholarly peer-reviewed content, so it does not qualify as a scholarly journal at all.

In hexadecimal notation, digits 0 through 9 map directly to decimal 0 to 9. After that, letters A, B, C, D, E and F represent decimal 10, 11, 12, 13, 14 and 15 respectively. Thus, decimal 12 is represented by hex digit C.

Option A:
Option A, A, corresponds to decimal 10 in hexadecimal notation. It is two less than 12 and therefore cannot represent decimal 12.

Option B:
Option B, B, stands for decimal 11, which is one less than 12. It is close but still not the correct mapping for 12.

Option C:
Option C, D, represents decimal 13 in hexadecimal. This is greater than 12 and therefore also not suitable.

Option D:
Option D is correct because the standard sequence assigns 12 to C. This mapping is used consistently in computer memory dumps, color codes and other hexadecimal contexts.

E-waste is a growing environmental concern resulting from rapid obsolescence of ICT devices. It includes any discarded or end-of-life electrical and electronic equipment and their components. Such waste can release toxic substances if not handled properly. Therefore, the option describing unwanted electronic equipment correctly defines e-waste in ICT contexts.

Option A:
This option focuses on organic agricultural waste, which is managed through separate environmental processes such as composting. It is not specific to ICT and does not involve electronic components. Hence, it does not represent e-waste.

Option B:
This option correctly identifies e-waste as encompassing various ICT hardware that has reached the end of its useful life. Items like computers, monitors and phones contain metals and chemicals that require specialised recycling. This aligns with standard environmental discussions on e-waste.

Option C:
Paper waste from printing is indeed a concern but falls under general solid waste or paper waste, not e-waste. It does not involve electronic circuitry or hazardous materials unique to ICT devices.

Option D:
Plastic bottles are a form of plastic waste and contribute to pollution but are not classified as e-waste. The term specifically refers to electronic items rather than general plastic products.

Statements A, B and D correctly describe IoT and its educational uses, whereas statement C is incorrect. A defines IoT as sensor-embedded physical objects that communicate over networks, which matches standard ICT usage. B is true because smart attendance systems and environmental sensors are typical examples of classroom IoT devices. D is also true, since data from such devices can be analysed for better campus and learning-space management. C is false because IoT applications depend on some form of network connectivity to exchange data and cannot always function in complete isolation.

Option A:
Option A is partly correct because statements A and B are true, but it omits D, which is also a correct and important statement. By excluding the role of analytics in using IoT data, this option does not capture the full set of true statements. Since at least one correct statement is missing, the option cannot be accepted as the best answer.

Option B:
Option B is correct because it includes exactly the true statements A, B and D and excludes the false statement C. It recognises the networked nature of IoT, its classroom applications and the analytical use of data for improvement. As it contains all and only the correct statements, it is the most accurate combination.

Option C:
Option C combines B and C and therefore mixes one true statement with one false statement. While B is correct about classroom IoT devices, C wrongly claims that IoT applications always work without connectivity. It also omits statement A and D, so this option is both incomplete and partially incorrect.

Option D:
Option D assumes that all four statements are correct, which would require accepting C as true. Because C misrepresents the need for network connectivity in IoT systems, including it makes the entire combination invalid. A correct option must exclude this false statement.

Statements A, B, C and E summarise key principles of data protection. Personal data is identifying information, data minimisation limits collection, access controls restrict who can see records and encryption protects data in transit and at rest. Statement D is false because unrestricted sharing conflicts with privacy obligations, and F is false since notices should clearly explain uses, not hide them. Thus A, B, C and E only are correct.

Option A:
Option A is incomplete because it omits E and does not mention how encryption supports confidentiality. A, B and C are true but do not cover all technical safeguards referenced in the question.

Option B:
Option B is incomplete because it leaves out B, ignoring the principle that institutions should not collect more data than necessary. A, C and E are correct, yet the combination is not exhaustive.

Option C:
Option C is correct because it includes conceptual and technical aspects of privacy protection while excluding permissive and opaque practices described in D and F. It aligns with responsible data management in education.

Option D:
Option D is incorrect because it introduces F, which advocates hiding information about data use. This contradicts transparency requirements, so mixing it with true statements makes the option wrong.

To convert 111.011₂ to decimal, we sum the weighted values of each bit. The integer part 111₂ equals 4 + 2 + 1 = 7. The fractional part .011₂ equals 0/2 + 1/4 + 1/8 = 0.375. Adding 7 and 0.375 gives 7.375. Therefore, the correct decimal equivalent is 7.375.

Option A:
If we interpreted the value as 7.25, the fractional part would need to be .01₂, which equals 0.25. However, 111.011₂ contains two fractional ones at positions 1/4 and 1/8, so the fraction is 0.375, not 0.25. Thus this option is not correct.

Option B:
7.375 matches the sum of 7 from the integer part and 0.375 from the fractional part .011₂. Each bit contributes correctly according to its negative power of two. This makes 7.375 the correct conversion from binary to decimal.

Option C:
A value of 7.5 would require the fractional part to be .1₂, corresponding to 0.5. Since the given binary fraction has bits in the 1/4 and 1/8 places instead, the value does not reach 7.5. Hence this option is incorrect.

Option D:
7.625 would correspond to .101₂ as the fractional portion, giving 0.625. The actual fraction .011₂ is 0.375, so 7.625 does not match the given binary fraction either.

Statement D is the only wrong statement because effective presenters typically avoid reading slides word-for-word and instead explain or elaborate key points. Statements A, B and C are consistent with good presentation design practices: concise text, controlled use of animations and high-contrast colours support attention and readability. Reading slides verbatim can disengage learners and reduce interaction. Hence the option that selects only D as wrong is correct.

Option A:
Option A is incorrect because it classifies both A and D as wrong, even though limiting text is a widely recommended practice. Too much text can overload learners and shift their focus away from explanations, so A should be considered correct.

Option B:
Option B is correct because it isolates D as the sole incorrect statement and thereby accepts A, B and C as design guidelines. It recognises that slide content should support rather than replace teacher explanation.

Option C:
Option C is incorrect because it treats C and D as wrong statements. C is true, since high-contrast colours (for example, dark text on a light background) generally improve readability. Grouping it with the false statement D makes this option invalid.

Option D:
Option D is incorrect because it labels B and D as wrong. While D is wrong, B is correct in noting that overuse of flashy effects can distract learners. Mixing a true statement with a false one prevents this option from being correct.

Statements A, B and C accurately describe how virtual labs extend experimental learning, whereas D is an overstatement. Virtual labs provide simulations and remote access that supplement physical labs and address resource constraints. They also support repeated practice and flexible access, especially in large or distance programmes. Yet, for some skills and disciplines, physical experimentation remains important, so D cannot be accepted as correct.

Option A:
Option A is correct because it selects the three true statements and excludes the extreme claim in D. It recognises virtual labs as powerful complements rather than complete replacements for physical laboratories. This balanced view is aligned with current practices in technology-enabled science education.

Option B:
Option B is incomplete because it includes only A and B and omits C. While A and B are true, statement C about data-logging and anytime access is also a common feature of virtual labs, so the set of correct statements is not fully represented.

Option C:
Option C is incorrect because it combines B and C with D and assumes all three are correct. Although B and C are true, D wrongly asserts that virtual labs make physical labs unnecessary in every discipline, which is not realistic.

Option D:
Option D is incorrect because it treats all four statements as correct and thereby accepts D. Since D conflicts with the complementary role of virtual and physical experimentation, this combination cannot be chosen.

Learning analytics collects traces of learner behaviour such as logins, page views, quiz attempts and assignment submissions. Dashboards and reports summarise these patterns and highlight students at risk or topics where many are struggling. Teachers can use this evidence to adjust pacing, provide remedial support or redesign assessments. Thus, its main purpose is to support data-informed improvements in teaching and learning.

Option A:
Randomly assigning grades would undermine fairness and academic standards. Learning analytics is introduced to make evaluation more evidence-based, not less.

Option B:
Deleting all activity records would remove the data needed for analysis and quality assurance. It contradicts the rationale for implementing analytics in the first place.

Option C:
Designing furniture and buildings is an architectural task. While enrolment numbers may influence space planning, this is not the central role of learning analytics in an LMS.

Option D:
This option correctly emphasises that analytics help teachers interpret patterns in student engagement and performance so they can make better pedagogical decisions.
