UGC NET Questions (Paper – 1)

Statements A, B, D and E accurately describe common features of collaborative document tools, while C and F are incorrect. Revision history and comments support transparent, iterative improvement, but do not guarantee error-free output. Offline sync broadens access, and flexible permissions control how participants interact with a document. Therefore, the combination A, B, D and E only is correct.

Option A:
Option A is incomplete because it leaves out E, thereby failing to acknowledge offline editing and later synchronisation—an important feature for users with intermittent connectivity.

Option B:
Option B is incomplete because it omits A, so it does not mention revision history and accountability for changes, which are central advantages of collaborative editing.

Option C:
Option C is correct because it groups all the true statements and excludes C’s claim about guaranteed perfection and F’s denial of integrations. It recognises collaborative tools as powerful yet still requiring human review.

Option D:
Option D is incorrect because it accepts F, which states that shared documents can never integrate with LMS or other systems. In practice, many platforms allow embedding or linking collaborative documents within course spaces.

Saving a document records the current state of the file on storage so that changes are not lost. Across many word processors, spreadsheets and other programs, Ctrl+S is the standard shortcut assigned to this action. This consistency encourages users to save frequently and avoid data loss. Thus, the shortcut for saving is Ctrl+S.

Option A:
Option A, Ctrl+O, is generally used to open an existing file rather than to save the current one.

Option B:
Option B is correct because software design guidelines often reserve Ctrl+S for the Save function, and users are trained to associate this combination with preserving their work.

Option C:
Option C, Ctrl+P, is linked with printing documents and opens a print dialogue, not a save dialogue.

Option D:
Option D, Ctrl+N, usually creates a new file or window and does not record the current document to disk.

E-waste refers to waste generated from discarded electronic devices, many of which contain hazardous substances such as heavy metals and plastics. Improper disposal can contaminate soil and water and affect human health. Responsible recycling and take-back policies are needed to manage e-waste sustainably. Hence, the materials described in the stem are e-waste.

Option A:
Option A, green energy, concerns renewable energy sources and does not describe discarded electronic devices.

Option B:
Option B is correct because environmental studies and ICT policy documents specifically label obsolete electronics as electronic waste or e-waste, emphasising their unique disposal challenges.

Option C:
Option C, biodegradable residue, refers to waste that can decompose naturally, whereas many electronic components persist in the environment for long periods.

Option D:
Option D, open data, denotes publicly accessible data sets and has no relation to physical waste.

A Local Area Network is designed to cover a limited geographical area such as a room, building or small campus. It provides high-speed connectivity among computers and devices within that confined space. LANs are common in schools, colleges, offices and laboratories for resource sharing. Therefore, this option accurately identifies the network type with a small physical scope.

Option A:
A Metropolitan Area Network covers a city or a large campus spread over tens of kilometres. It is much larger in scope than a single building. Because of this wider coverage, MAN does not best represent the small-area network described in the question.

Option B:
A Wide Area Network spans very large geographical areas, sometimes across countries or continents. The Internet itself is an example of a WAN. Since the question emphasises a single building or small campus, WAN is far beyond the required scope.

Option C:
A Virtual Private Network is a secure tunnel created over existing networks such as the Internet. It describes a method of secure communication rather than the physical size of the network. Hence, it does not directly answer the question about geographical coverage.

Option D:

To convert 345 to binary, we repeatedly divide by 2 and record remainders. This process yields the bit pattern 101011001 when read from last remainder to first. We can verify by expanding 101011001 as 2^8 + 2^6 + 2^4 + 2^3 + 2^0. This equals 256 + 64 + 16 + 8 + 1 = 345, confirming that 101011001 is correct.

Option A:
Option A, 100101001, corresponds to a different decimal value. If expanded, it sums to 256 + 32 + 8 + 1 = 297. Since 297 is not equal to 345, this binary representation is not correct for the given decimal number.

Option B:
Option B, 101011001, represents 256 + 64 + 16 + 8 + 1 = 345. This matches the target decimal value exactly. Both the division method and place value expansion confirm this match. Therefore, this is the correct 9-bit binary representation of 345.

Option C:
Option C, 101001011, gives yet another decimal value. Its expansion is 256 + 64 + 8 + 2 + 1 = 331. Because 331 differs from 345, this option cannot be the correct binary encoding for 345.

Option D:
Option D, 100011001, expands to 256 + 16 + 8 + 1 = 281. This again fails to equal 345. As a result, this binary pattern does not represent the required decimal number and must be rejected.

Operating systems can offer different styles of interaction. Command line shells take typed commands and display text output, offering powerful control for experienced users. Graphical interfaces present icons, buttons and menus that users can manipulate using a mouse or touch, making basic operations easier for beginners. This contrast in interaction mode is the central difference between CLI and GUI.

Option A:
This option incorrectly reverses the characteristics, claiming CLIs use pictures and GUIs use only text. In reality, CLI environments are textual while GUIs are graphical.

Option B:
Option C introduces handwriting as a requirement, which is not true for either interface type. While touchscreens may accept handwriting, it is not a defining feature of CLI or GUI.

Option C:
Option D is wrong because both interfaces typically support file management commands or actions, such as creating folders, copying files and deleting documents.

Option D:

Statements A, B and D provide a realistic view of VR and AR in education, while C dismisses their educational potential. VR and AR can create immersive and context-rich learning experiences, but their adoption is constrained by cost and complexity. Many educational simulations and visualisations already use these technologies. Thus, the correct combination includes A, B and D and excludes C.

Option A:
Option A is incomplete because it includes only A and B and ignores D. Recognising the challenges described in D is important for a balanced understanding of VR and AR implementation in real classrooms.

Option B:
Option B is incorrect because it groups B and C and treats both as correct. While B accurately describes AR, C falsely claims that the technologies have no educational relevance, contradicting current practice.

Option C:
Option C is incorrect because it combines A, C and D, thereby accepting C. Although A and D are true, C undermines the educational value of VR and AR, so the combination cannot be accepted.

Option D:
Option D is correct because it gathers the three true statements and sets aside C, which is inconsistent with the growing use of VR and AR in educational contexts.

Statements A, B, C, E and F summarise sound practices for participating in educational video conferences, while D is unnecessarily restrictive. Muting, making connectivity stable, protecting meeting links, using headsets and checking video setup all support clear and secure communication. Chat features are often encouraged for questions, especially in large webinars where voice interruptions can be disruptive. Therefore D is not correct, and the set of true statements is A, B, C, E and F.

Option A:
Option A is incorrect because it omits F, which highlights the importance of camera framing and lighting. While A, B, C and E are true, ignoring visual presentation overlooks a key aspect of professional online presence. Hence this combination does not include all correct statements.

Option B:
Option B is incorrect because it excludes C, thereby failing to acknowledge risks of posting meeting links publicly. Without C, the combination does not address security threats such as unwanted intrusions into educational sessions. As a result, it is incomplete.

Option C:
Option C is correct because it includes A, B, C, E and F, all of which promote effective and secure participation. It explicitly excludes D, which wrongly discourages the constructive use of chat for questions. This makes Option C the only set that aligns with recommended etiquette for educational video conferencing.

Option D:
Option D is incorrect because it leaves out A, which recommends muting microphones when not speaking. Although B, C, E and F are true, omitting A neglects a basic practice for maintaining audio clarity in group calls. Therefore this option cannot be the correct answer.

A screenshot records exactly what appears on the screen at a given moment, preserving the arrangement of windows and content. It is useful for documenting errors, creating tutorials or saving visual information. Most operating systems provide built in shortcuts or tools for taking screenshots. Hence, the captured display image is called a screenshot.

Option A:
Option A, bookmark, saves the address of a web page for later access and does not capture its visual appearance.

Option B:
Option B is correct because screenshot is the widely used term for an image of the screen taken by software rather than a camera.

Option C:
Option C, hyperlink, refers to a clickable reference that navigates to another resource, which is unrelated to image capture.

Option D:
Option D, wallpaper, is the background image displayed on the desktop, not a capture of current screen contents.

Statements A, B, C, E and F describe key assistive technologies and inclusive features, while D conflicts with proactive design. Screen readers, speech recognition and captions address specific impairments, and customisable visual settings and built-in tools help many learners. Considering accessibility only after a request can leave barriers in place and slow down support. Thus the correct set is A, B, C, E and F.

Option A:
Option A is incorrect because it omits F, thereby underestimating the value of built-in accessibility features for a broad user base. A, B, C and E are true but do not reflect the universal design perspective captured by F.

Option B:
Option B is incorrect because it omits A and adds nothing about screen readers. B, C, E and F are true, yet excluding A leaves out one of the most central assistive tools for blind learners.

Option C:
Option C is correct because it assembles statements about multiple assistive tools and emphasises that accessibility benefits many learners. It explicitly rejects D’s reactive approach by not including it.

Option D:
Option D is incorrect because it omits B and therefore fails to mention speech recognition. A, C, E and F are true, but leaving out B means the set is incomplete.

Statements A, B and C collectively show how ICT can widen access to teacher development programmes while promoting collaboration and flexibility. Online events and communities reduce logistical barriers and enable sharing of practice. Statement D is false because many professional development models still benefit from or deliberately include face-to-face components. Therefore the correct set of statements is A, B and C only.

Option A:
Option A is incorrect because it includes only A and B and omits C. While A and B are true, C is also correct in highlighting the benefits of flexibility and reduced travel costs. Excluding C gives an incomplete picture of ICT-based professional development.

Option B:
Option B is incorrect because it lists A and C only and leaves out B. Statement B is important in recognising the role of online communities and forums where teachers can learn from peers. Without B, the collaborative dimension is underplayed.

Option C:
Option C is correct because it groups A, B and C as true, covering content, pedagogy and logistics of teacher development. It deliberately excludes D, which wrongly assumes that online formats must completely replace in-person interaction.

Option D:
Option D is incorrect because it suggests that B, C and D are correct, thereby accepting D. In reality, blended models that mix online and face-to-face components are common and effective.

The decimal number 2047 is equal to 2¹¹ − 1, which is the largest number representable with eleven binary bits. In hexadecimal, this boundary value appears as 7FF. 7FF₁₆ expands to 7×16² + 15×16¹ + 15×16⁰ = 1792 + 240 + 15 = 2047. Therefore 7FF is the correct hexadecimal representation.

Option A:
7EF₁₆ equals 7×256 + 14×16 + 15 = 1792 + 224 + 15 = 2031. This value is slightly less than 2047, so it cannot be the correct representation.

Option B:
7FF₁₆ gives 1792 + 240 + 15 = 2047, matching the decimal in the question exactly. It highlights the pattern that just before a power of sixteen, all lower hex digits become F.

Option C:
8FF₁₆ stands for 8×256 + 15×16 + 15 = 2048 + 240 + 15 = 2303. Since this is larger than 2047, it overshoots the target and is not correct.

Option D:
6FF₁₆ represents 6×256 + 15×16 + 15 = 1536 + 240 + 15 = 1791. This is much smaller than 2047, so it cannot match the required decimal number.

Open source software is defined by the freedom to access and modify the source code, usually under licences that allow redistribution. This model encourages collaboration and community based development. In ICT education, open source tools are often promoted for flexibility and cost effectiveness. Thus, the description in the stem clearly refers to open source software.

Option A:
Option A is correct because open source directly captures the idea of accessible source code and the right to modify and share, which is central to the definition. Many operating systems, learning platforms and office suites used in education follow this model.

Option B:
Option B, proprietary, software keeps source code closed and restricts modification and redistribution, which is the opposite of what the question describes. Users must follow strict vendor licence terms.

Option C:
Option C, freeware, is free of cost to use but may still have closed source code and restrictive licences. Freeware does not guarantee modification rights.

Option D:
Option D, shareware, allows users to try software for a limited time or with limited features, often requiring payment later, and does not necessarily provide source code access.

In synchronous e learning, teacher and learners interact at the same time through digital tools such as webinars and live chats. Participants can ask questions, receive immediate feedback and collaborate while the session is in progress. A live webinar exemplifies this real time engagement. Consequently, the correct term to fill the blank is synchronous.

Option A:
Option A is correct because synchronous e learning is explicitly defined as real time online interaction, which matches the description of the webinar.

Option B:
Option B, asynchronous, would apply to activities like viewing recorded sessions or participating in forums at different times, not to live events.

Option C:
Option C, blended, refers to combining online and face to face methods and does not specify the timing of interaction.

Option D:
Option D, independent, study suggests self directed learning without real time interaction with teachers or peers.

Statements A, B and D accurately describe how online collaboration tools function, while statement C is false. Shared documents and wikis enable multiple users to co-author text, version histories show who changed what and commenting supports feedback. The claim that such tools cannot be used for group projects contradicts their widespread educational use. Thus, the combination A, B and D only is correct.

Option A:
Option A is incorrect because it includes only A and B and omits D. While A and B are true, D is also correct in highlighting the significance of commenting and annotation tools for feedback. Excluding D means the set is incomplete.

Option B:
Option B is incorrect because it groups A, B and C as correct statements. Including C is problematic because it denies the very purpose of collaboration tools in group work. Mixing a false statement with true ones prevents this option from being correct.

Option C:
Option C is incorrect because it lists B, C and D as correct. Statements B and D are accurate, but C is false, and any option that accepts C cannot be right. In addition, this combination leaves out statement A, which is also true.

Option D:
Option D is correct because it collects A, B and D, the three statements that fit real-world classroom use of collaboration platforms. It rejects C, which incorrectly restricts these tools, thereby giving a complete and accurate picture of their educational value.
