UGC NET Questions (Paper – 1)

Compression encodes data more compactly, so files occupy less storage and need less bandwidth, speeding up transfers and saving resources.

Option A:
Resolution and quality are set when data is created; compression cannot magically increase original resolution and may even reduce quality in lossy schemes.

Option B:
This option correctly states the main practical benefit: smaller files mean more efficient storage and transmission.

Option C:
Lossless methods preserve all information, but lossy methods discard some details; so not all compression is information-perfect.

Option D:
Malware protection is the domain of security tools like antivirus and firewalls, not compression algorithms.

The decimal 0.5 equals 1/2, which is exactly one power of 2 in the denominator. In binary fractions, 0.1₂ represents 1×2^-1, which equals 1/2 or 0.5 in decimal. Therefore, the correct binary representation of 0.5 is 0.1₂.

Option A:
Option A is correct because it assigns a 1 to the 2^-1 place and zeros elsewhere, giving 1/2. This matches the decimal fraction exactly.

Option B:
Option B, 0.01₂, represents 1×2^-2 which equals 1/4 or 0.25. This is smaller than 0.5 and cannot be the correct equivalent.

Option C:
Option C, 0.11₂, equal to 1×2^-1 + 1×2^-2, gives 1/2 + 1/4 = 3/4. This is larger than 0.5 and therefore incorrect.

Option D:
Option D, 1.0₂, equals 1 in decimal and represents a whole number rather than a fraction. It does not correspond to 0.5.

Under UGC guidelines, universities may approve certain SWAYAM or other recognised MOOCs and allow the credits earned to count towards a student’s degree. When a student formally enrols, completes assessments, earns credits and has them transferred into the university programme, it demonstrates proper regulated use of MOOCs for credit transfer.

Option A:
This option correctly shows a student completing an approved SWAYAM course, earning credits through assessment and having those credits added to their academic record in line with institutional and UGC rules.

Option B:
Randomly watching online videos without formal enrolment, assessment or institutional approval does not meet academic standards for credit, so this behaviour cannot legitimately earn degree credits.

Option C:
A university that refuses to recognise any online learning even when regulations permit limited MOOC credits is not using the credit-transfer provision at all, so this does not illustrate it.

Option D:
Banning students from using online platforms for supplementary learning goes against the spirit of integrating ICT and MOOCs into higher education and involves no credit transfer.

ICT tools like online quizzes can process responses instantly and display results on the screen, allowing teachers to respond in real time. This immediacy supports formative assessment by helping teachers identify misconceptions while the lesson is in progress. Immediate feedback also motivates learners because they see the results of their efforts quickly. Therefore, the primary benefit mentioned in the stem is that ICT enables immediate feedback.

Option A:
Option A refers to delayed feedback, which may occur when assessments are checked manually instead of using ICT; it does not capture the real time nature highlighted in the question. Delayed feedback can still be useful, but it does not leverage the speed of digital tools. Hence, it is less aligned with the main advantage described.

Option B:
Option B is correct because the defining feature of many ICT based assessment tools is their capacity to generate immediate responses to learner input. This immediate feedback loop allows for quick correction, adaptive teaching and increased engagement, making it the best fit for the blank.

Option C:
Option C suggests random feedback, which would confuse learners rather than support learning, and it does not reflect how ICT systems are programmed to return accurate results based on responses. Randomness contradicts the purpose of assessment.

Option D:
Option D, irrelevant feedback, would not be connected to the learning objectives and would undermine the effectiveness of ICT integration in teaching. ICT is adopted precisely to provide relevant, targeted feedback.

Statements A, B, D and E correctly describe plagiarism and academic integrity. Plagiarism is using others’ work without acknowledgment, citation prevents it, self-plagiarism can occur when reusing work without permission and instruction on citation and paraphrasing supports ethical writing. Statement C is false because accessibility does not cancel the need for attribution, and F is false since tools do not replace understanding of referencing. Therefore A, B, D and E only are correct.

Option A:
Option A is incomplete because it omits E and hence ignores the role of explicit teaching about citation and paraphrasing. While A, B and D are true, the set does not include all correct statements.

Option B:
Option B is correct because it includes all valid explanations of plagiarism and preventive education while excluding justifications for unacknowledged copying and overreliance on tools. It matches accepted academic norms.

Option C:
Option C is incorrect because it incorporates C, which claims copying from freely accessible websites without attribution is acceptable. This violates academic integrity, supporting the view that the combination cannot be accepted.

Option D:
Option D is incorrect because it omits A and thus fails to state the basic definition of plagiarism. Although B, D and E are correct, leaving out A means not all essential statements are included.

Statements A, B and D are standard recommendations for email security, while C encourages risky behaviour and is wrong. Phishing attempts often mimic banks, universities or service providers to harvest credentials. Users should inspect URLs and report suspicious messages so that filters can be updated and warnings issued. Urgency cues are commonly abused in scams and do not guarantee safety of attachments.

Option A:
Option A is incomplete because it lists only A and B and omits D. While recognising phishing patterns and checking links is important, reporting incidents also strengthens organisational defences.

Option B:
Option B is incorrect because it includes A, B and C and thus accepts C. Since attackers deliberately send urgent messages with harmful attachments, this advice would expose users to unnecessary danger.

Option C:
Option C is correct because it combines awareness of phishing, verification of links and the organisational step of reporting suspicious emails. By excluding C, it rejects the unsafe idea that urgency alone can justify opening unknown attachments.

Option D:
Option D is incomplete because it groups B and D only and leaves out A. Statement A provides the basic description of phishing, without which the rationale for the other actions becomes less clear.

SWAYAM Prabha leverages satellite and DTH technology to broadcast lectures and educational programmes for school, college and competitive exam preparation. The channels run round the clock with repeating schedules, allowing learners to watch according to convenience. This initiative complements Internet-based platforms by reaching households that may lack reliable broadband. Thus, the focus on educational DTH channels is central.

Option A:
This option accurately states that SWAYAM Prabha uses ICT-enabled broadcasting to deliver curriculum-based content on dedicated television channels throughout the day. It captures the core objective of the scheme.

Option B:
This option refers to commercial cinema distribution of entertainment movies, which is unrelated to government-supported educational broadcasting.

Option C:
This option about sports tournaments does not describe any content-delivery scheme and has no mention of ICT-based television learning.

Option D:
This option suggests relying only on printed books, contradicting SWAYAM Prabha’s emphasis on audiovisual digital content delivered via DTH.

Data backup strategies are implemented to ensure that information can be restored if the primary storage device fails or files become corrupted by malware or errors. By keeping copies on separate media or in the cloud, organisations reduce the risk of permanent loss. This is a key aspect of ICT risk management and continuity planning. Therefore, backups mainly protect against hardware failure and corruption.

Option A:
Option A is correct because hardware breakdowns and file corruption are among the most common causes of data loss, and backup systems are specifically designed to mitigate these problems.

Option B:
Option B, increased redundancy, describes having duplicates but does not fully capture the underlying threat; redundancy is the means rather than the risk being addressed.

Option C:
Option C, user convenience, may be a secondary benefit but is not the primary reason for systematic backup procedures.

Option D:
Option D, faster processing, relates to performance improvements and is not a direct outcome of creating backup copies.

A printer takes digital documents from a computer and converts them into printed output on paper or other media. It is therefore classified as an output device because information flows from the computer to the external world. Printers can use different technologies such as inkjet, laser or dot matrix. Thus the hard-copy device described in the question is a printer.

Option A:
Option A, mouse, is used for pointing and clicking and is an input device, not one that produces printed output. It helps control the computer rather than generate hard copies.

Option B:
Option B, microphone, converts sound into electrical signals and is used to input audio, so it cannot be the device mentioned in the stem.

Option C:
Option C, scanner, captures images or text from paper into the computer and is therefore an input device, opposite in function to a printer.

Option D:
Option D is correct because producing printed text or graphics is the primary function associated with printers in ICT and office environments.

A keylogger is designed to monitor and record keystrokes on a keyboard without the user's knowledge. The captured information is often sent to attackers who may misuse passwords, credit card numbers or personal messages. Such tools pose a serious risk to privacy and security, especially on shared or public computers. Hence, the malicious program described is a keylogger.

Option A:
Option A, worm, is a self replicating program that spreads across networks but does not necessarily log keystrokes. Its primary behaviour is to propagate, not to capture user input.

Option B:
Option B, Trojan horse, disguises itself as legitimate software but typically opens a backdoor or performs other hidden actions rather than exclusively recording keystrokes.

Option C:
Option C is correct because keyloggers are explicitly defined as programs that log and store keystrokes, which is exactly what the stem describes. They are often categorised as a form of spyware.

Option D:
Option D, antivirus, is defensive software used to detect and remove malware and is not itself a malicious program.

In octal 157₈, the digits are in the 8^2, 8^1 and 8^0 positions. The value is 1×64 + 5×8 + 7×1. This computes as 64 + 40 + 7 = 111. Thus, the decimal equivalent of 157₈ is 111.

Option A:
Option A, 107, is smaller than 111 and would result from a different combination, such as 151₈. It does not match the actual weighted sum.

Option B:
Option B, 108, also fails to equal 64 + 40 + 7. It appears to be a guess near the correct answer but is not supported by correct calculation.

Option C:
Option C, 110, is close but still one less than the correct value of 111. This again indicates a small arithmetic error.

Option D:
Option D is correct because the precise computation of 1×64 + 5×8 + 7 gives exactly 111. This follows the general method of converting from octal to decimal.

Feedback involves sending information back to the source about the effectiveness of a message or performance. In ICT based learning, quizzes that immediately show scores and explanations give students feedback on their understanding. This supports self regulation and instructional improvement. Hence, the communication function being supported is feedback.

Option A:
Option A is correct because feedback is recognised in educational communication models as the response that informs both teacher and learner about learning progress.

Option B:
Option B, control, can be a managerial function but does not specifically describe the information returned about learning outcomes.

Option C:
Option C, entertainment, may motivate learners but is not the central communicative function described.

Option D:
Option D, noise, refers to disturbances in communication, not to structured responses on performance.

Statements A, B, C and E capture key aspects of reliable backup strategies, whereas D and F are unsafe. Regular and documented backups to separate locations, along with test restorations, help institutions recover from failures or disasters. Keeping only one copy is not a backup at all, and performing backups only once a year ignores day-to-day data changes. Thus the correct set excludes D and F and includes A, B, C and E.

Option A:
Option A is incorrect because it omits A, which stresses regular backups to reduce loss, and it includes F, which wrongly suggests backups only once a year are sufficient. Therefore this set is not correct.

Option B:
Option B is incorrect because it includes F and omits C. Adding F suggests that annual backups are sufficient, which is inappropriate for dynamic institutional data. Leaving out C removes reference to documented schedules, so this option is not acceptable.

Option C:
Option C is correct because it encompasses regular backups, off-site storage, clear schedules and test restorations as a coherent strategy. It properly rejects D’s and F’s oversimplified approaches that expose data to unnecessary risk.

Option D:
Option D is incorrect because it includes F and omits B. Without B, there is no protection against local disasters, and including F implies very infrequent backups, so this combination cannot be correct.

Inclusive education aims to ensure that all learners can participate meaningfully in learning activities. ICT makes this possible through tools like screen readers, magnifiers, captioning and alternative input devices. When materials are provided in accessible digital formats, visually impaired students can use assistive software to access the same content as their peers. Therefore, offering screen-reader friendly electronic text is a strong example of ICT-based inclusion.

Option A:
This option correctly recognises that accessibility involves both content format and compatible technologies. By structuring text properly and avoiding unnecessary barriers, institutions can enable equal access to readings, lectures and assessments.

Option B:
Small print with no alternative formats creates barriers for students with visual difficulties. Without digital or larger-print options, they may be excluded from learning.

Option C:
Excluding students with disabilities from computer labs contradicts the principle of inclusion and wastes the potential of assistive technologies. The lab should be adapted, not restricted.

Option D:
Poor colour contrast or overly complex visual design can make content hard to read, especially for learners with low vision or colour blindness. Good ICT design emphasises readability and flexibility.

Converting 1729 to binary by repeated division by 2 gives the remainder sequence that reconstructs as 11011000001₂. Expanding 11011000001₂ as 1×1024 + 1×512 + 0×256 + 1×128 + 1×64 + 0×32 + 0×16 + 0×8 + 0×4 + 0×2 + 1×1 yields 1729. This confirms that the binary string exactly matches the decimal number. Thus option A is the correct representation.

Option A:
11011000001₂ uses bits set in positions corresponding to 1024, 512, 128, 64 and 1. Adding these values gives 1729, which matches the decimal number. The presence of zero bits in all other positions preserves this sum exactly, making this option correct.

Option B:
11011100001₂ includes an additional 256 contribution compared to the correct pattern because of the extra 1 in a higher position. Its expansion becomes 1024 + 512 + 256 + 64 + 1 = 1857, which is larger than 1729. Hence this pattern is not correct.

Option C:
11011000010₂ shifts one of the 1 bits to the 2¹ position instead of the 2⁰ position. That makes the total 1024 + 512 + 128 + 64 + 2 = 1730. Because 1730 is not equal to 1729, this option is numerically incorrect.

Option D:
10111000001₂ uses 1024 + 256 + 128 + 64 + 1 = 1473 as its decimal value. This is significantly smaller than 1729, showing that its pattern of ones in high-order bits differs from the correct one. Therefore it is not the correct representation for 1729.
