UGC NET Questions (Paper – 1)

JPEG and PNG are widely used raster image formats suitable for photographs and diagrams on the web and in presentations. JPEG supports lossy compression, making it good for photos, while PNG offers lossless compression and transparency. Both are supported by almost all browsers and presentation software. Therefore, they correctly represent typical image file formats.

Option A:
Option A is correct because ICT courses commonly cite JPEG and PNG as standard image formats, and their properties are tailored to visual media rather than text or audio.

Option B:
Option B, DOCX and XLSX, are office document formats for word processing and spreadsheets, not for storing standalone digital images.

Option C:
Option C, MP3 and WAV, are audio file formats used for sound recordings and cannot substitute for image formats.

Option D:
Option D, PDF and PPTX, represent document and presentation formats that may contain images but are not image formats themselves.

The hex number 16D₁₆ has digits 1, 6, and D. Using positional weights, we compute 1×16² + 6×16¹ + 13×16⁰ = 1×256 + 6×16 + 13×1 = 256 + 96 + 13 = 365. Therefore, 16D₁₆ equals 365 in decimal.

Option A:
Option A correctly interprets D as 13 and applies the weights 256, 16, and 1. The sum 256 + 96 + 13 yields 365, matching the result of a proper base-16 to base-10 conversion.

Option B:
Option B, 349, represents a different combination of digit values and weights and does not equal the computed sum of 1×256 + 6×16 + 13. It indicates an arithmetic or mapping error.

Option C:
Option C, 269, underestimates the value and would imply lower contributions from the hex digits than they actually have. It does not correspond to the given pattern.

Option D:
Option D, 285, neither matches the correct total nor any plausible misinterpretation that preserves digit order while using appropriate weights.

101011110101₂ has 1s at positions 11, 9, 7, 6, 5, 4, 2, and 0. So value = 2¹¹ + 2⁹ + 2⁷ + 2⁶ + 2⁵ + 2⁴ + 2² + 2⁰ = 2048 + 512 + 128 + 64 + 32 + 16 + 4 + 1 = 2805.

Option A:
Option A is correct because summing the powers of 2 for all set bits gives exactly 2805.

Option B:
Option B (3019) would require additional higher-order bits or different set-bit positions.

Option C:
Option C (3442) corresponds to a different binary pattern with larger contributions than present here.

Option D:
Option D (3285) also corresponds to a different set of bit positions and does not match this binary numeral.

Statements A, B, D and E describe key affordances and limitations of digital note-taking. Tools enable structured organisation, synchronisation across devices and quick retrieval through search, but they do not remove the need for selective recording and active processing by students. Statement C is false because many tools support images, links and even audio. Statement F is false since understanding depends on how notes are used for review and elaboration, not simply on the medium, so the correct set keeps A, B, D and E only.

Option A:
Option A is incomplete because it omits E, and thus fails to highlight the ongoing need for strategic note-making. A, B and D focus on features but not on learner responsibility, so the combination is partial.

Option B:
Option B is incorrect because it includes F, which suggests that using digital tools alone guarantees deep understanding. This ignores the importance of revision, reflection and practice, so adding F makes the set inaccurate.

Option C:
Option C is incorrect because it also includes F and leaves out A. Omitting A ignores organisational advantages, and accepting F exaggerates the effect of technology on learning outcomes. As a result, this option cannot be accepted.

Option D:
Option D is correct because it acknowledges both the power and the limits of digital tools. It captures organisation, access and search while insisting that students still must actively decide what and how to record, which matches educational research on note-taking.

Cascading Style Sheets separate the presentation of web content from its structure by allowing designers to define styles in one place and apply them across pages. CSS rules control layout, fonts, colours and other visual properties. This improves maintainability and consistency of websites. Hence, the styling language is Cascading Style Sheets.

Option A:
Option A is correct because Cascading Style Sheets is the standard expansion of CSS used in web development.

Option B:
Option B, Hyperlink Styling System, is not the recognised name and narrows the focus incorrectly to hyperlinks.

Option C:
Option C, Computer Style Script, is an invented phrase and not part of official web technology terminology.

Option D:
Option D, Content Sheet Syntax, does not accurately reflect the role or established name of CSS.

A Massive Open Online Course (MOOC) combines massiveness, openness and online delivery, allowing thousands of learners to enrol without traditional entry barriers. Content is typically accessed through videos, readings and quizzes on web platforms. MOOCs exemplify global reach and flexible participation enabled by ICT. Therefore, the type of course described in the stem is a MOOC.

Option A:
Option A, limited correspondence course, suggests restricted enrolment and postal-based communication rather than an open, internet-based model.

Option B:
Option B is correct because the full phrase massive open online course precisely matches the characteristics of being large scale, open and web-based described in the question.

Option C:
Option C, closed campus programme, indicates physical attendance and limited seats, which is opposite to the openness and scalability of MOOCs.

Option D:
Option D, local evening class, is tied to a specific location and schedule and does not utilise worldwide online access.

777₈ = 7×8² + 7×8¹ + 7×8⁰ = 7×64 + 7×8 + 7 = 448 + 56 + 7 = 511.

Option A:
Option A correctly computes the base-8 expansion to 511.

Option B:
Option B (512) equals 8³ and corresponds to 1000₈.

Option C:
Option C (343) is 7³ and unrelated to 777₈’s place weights.

Option D:
Option D (409) is not the correct positional sum.

The binary number system is defined as a positional system that uses only two symbols, 0 and 1, so its base must be 2. In any positional number system, the base equals the number of distinct digit symbols available. All place values in binary, such as 1, 2, 4, 8 and so on, are powers of 2. Therefore, the only correct base for the binary system among the options is 2.

Option A:
Option A is correct because binary has exactly two symbols and therefore a base of 2. Every binary position corresponds to 2 raised to some power, which shows that the base is 2. Without base 2, the structure of binary place values would not work correctly.

Option B:
Option B refers to base 8, which is used in the octal system, not in binary. Octal digits range from 0 to 7 and thus require eight different symbols. Therefore base 8 cannot describe a system that has only two digits, 0 and 1.

Option C:
Option C refers to base 10, which belongs to the decimal system, the usual system for everyday counting. Decimal uses ten symbols from 0 to 9, unlike binary which uses only 0 and 1. Hence 10 cannot be the base of the binary system.

Option D:
Option D refers to base 16, which is associated with the hexadecimal system. Hexadecimal uses symbols 0–9 and A–F to represent sixteen distinct values. This makes it unsuitable as a base for binary, which has only two symbols.

An Online Public Access Catalogue (OPAC) is a digital interface to a library's bibliographic database, enabling users to search holdings by various fields. It replaces traditional card catalogues and provides quicker, more flexible access to collection information. Modern OPACs may be accessible via the web from outside the library premises. Therefore, the system described in the stem is an OPAC.

Option A:
Option A is correct because the full form "online public access catalogue" is standard in library science, and the functions listed match those offered by OPACs.

Option B:
Option B, online personal article collection, is not a recognised term and would suggest a private store rather than a library's public catalogue.

Option C:
Option C, offline print accession card, refers to older manual cataloguing systems and does not involve computer interfaces.

Option D:
Option D, open password authentication check, sounds like a security procedure rather than a tool for searching library collections.

A digital signature uses algorithms and keys to bind the identity of a signer to a digital document in a way that tampering can be detected. It is legally recognised in many jurisdictions and supports secure e governance and e commerce. Unlike a mere image of a handwritten name, a digital signature has cryptographic strength. Thus, the method described is a digital signature.

Option A:
Option A is correct because digital signature is the standard term for cryptographically generated signatures used in secure electronic transactions.

Option B:
Option B, manual, signature refers to handwritten marks on paper and does not inherently support electronic verification or integrity checks.

Option C:
Option C, scanned, signature is just a picture of a manual signature and can be copied or altered without cryptographic safeguards.

Option D:
Option D, symbolic, signature is not a formal category in information security and could refer to any representation, lacking precise meaning.

Statements A, B and C correctly outline prudent backup and compression practices, while D contradicts basic safety principles. Backups should be redundant and ideally off-device, with cloud services offering off-site resilience. Compression is a common method to save storage space or bandwidth but does not replace the need for multiple copies. Relying on a single device creates a single point of failure, so D is not acceptable. Therefore, the correct combination is A, B and C only.

Option A:
Option A is incomplete because it includes A and B but omits C. Although backups are central, understanding compression as a complementary strategy for efficient storage and transfer is also important.

Option B:
Option B is incomplete because it lists B and C only and leaves out A. Statement A emphasises the broader rationale for backup practices and should not be excluded when discussing data protection.

Option C:
Option C is correct because it brings together all the true statements about backups and compression and excludes the unsafe recommendation in D. It reflects the need for multiple copies and thoughtful storage management in ICT use.

Option D:
Option D is incorrect because it mixes A and C with D and treats D as correct. Suggesting that a single copy on one device is a good backup strategy exposes data to high risk of loss, so this option cannot be correct.

Plagiarism detection tools use text-matching algorithms to highlight similarities between a student's work and existing documents. They generate similarity reports that help instructors judge whether proper citation has been used. Such tools support academic integrity policies by discouraging copying without attribution. Therefore the software described is best classified as plagiarism detection software.

Option A:
Option A, translation, focuses on converting text from one language to another and does not systematically compare submissions with source databases for similarity checks.

Option B:
Option B, scheduling, assists in organising timetables or tasks and has no role in analysing textual originality.

Option C:
Option C is correct because the key functionality mentioned—comparing files to large repositories to flag overlaps—is the hallmark of plagiarism detection systems like Turnitin or other university tools.

Option D:
Option D, bandwidth monitoring, tracks network usage and traffic flows and is concerned with resource management rather than academic writing practices.

Presentation software enables users to design slide shows with structured content, visuals and animations to support lectures and talks. It enhances the clarity and visual appeal of classroom communication. Because its primary purpose is to present information to audiences, it is called presentation software.

Option A:
Option A is correct because presentation software is the standard term for tools that create and display slide based visual aids, fitting the description in the question.

Option B:
Option B, statistical, software is used for advanced data analysis and does not focus on creating slides.

Option C:
Option C, antivirus, software provides security functions and has no direct role in preparing teaching slides.

Option D:
Option D, database, software manages structured data in tables and is not used primarily for presentations.

Statements A, B and D correctly describe how ICT can strengthen formative assessment, while statement C is clearly false. Online quizzes and response systems give immediate feedback and real-time snapshots of understanding, and analytics dashboards help teachers see trends and adjust instruction. Saying that ICT cannot provide data for improvement contradicts the very purpose of these tools. Therefore the accurate combination is A, B and D only.

Option A:
Option A is incomplete because it includes only A and B and omits D. While immediate feedback and in-class polling are important, learning analytics dashboards described in D also play a significant role in ongoing monitoring. Excluding D leaves out a major benefit of ICT-supported assessment.

Option B:
Option B is incorrect because it groups B and D only and ignores A. Statement A about online quizzes is central to formative assessment practice in many digital environments. Without it, the set of statements is incomplete.

Option C:
Option C is incorrect because it presents A, B and C as correct and thereby accepts C. Statement C negates the data-rich possibilities of ICT and conflicts with how formative assessment systems are used. Including it invalidates this combination.

Option D:
Option D is correct because it collects all the true statements and rejects C, which mischaracterises ICT-supported assessment. It highlights feedback, diagnosis and data-informed teaching as key outcomes.

Frequency Division Multiplexing divides the channel into multiple narrower frequency ranges, each allocated to a separate signal. This allows several users or data streams to share the same medium at the same time without interfering, provided the bands are carefully separated. It has been widely used in radio, television and older telephone systems. Hence, the technique described in the stem is frequency division multiplexing.

Option A:
Option A is correct because it explicitly states the idea of dividing available bandwidth into frequency bands, which exactly matches the definition of frequency division multiplexing.

Option B:
Option B, time division switching, suggests allocating different time slots rather than frequency bands and relates more to time based sharing.

Option C:
Option C, packet switching, involves breaking data into packets and routing them independently over digital networks, which is conceptually different from analog frequency sharing.

Option D:
Option D, encapsulation, refers to the process of wrapping data with protocol information as it moves down the layers of a protocol stack and does not involve dividing bandwidth.
