UGC NET Questions (Paper – 1)

Statements A, B and D present a realistic view of how mobile LMS apps support learning, whereas C is too extreme. Smartphones can extend access to course content and reminders, but they do not completely eliminate the usefulness of larger screens or specialised software on desktops and laptops. Designing resources for mobile delivery demands careful attention to limited space and connectivity. Therefore, the combination containing A, B and D but excluding C is correct.

Option A:
Option A is incomplete because it includes only A and B and omits D. While access and notifications are important, ignoring design considerations may lead to content that is hard to use on small screens.

Option B:
Option B is incomplete because it lists B and D only and leaves out A. Without acknowledging that many LMS platforms actually have mobile apps, statements about notifications and design lack context.

Option C:
Option C is incorrect because it groups A and D but also includes C as implied correct. Statement C wrongly claims that mobile access fully replaces other devices, which does not match real usage patterns where multiple devices coexist.

Option D:
Option D is correct because it assembles the three true statements, highlighting access, reminders and design constraints while rejecting the unrealistic claim in C. It reflects the blended ecosystem of devices used in higher education.

Statement D is the only wrong statement because mobile learning specifically emphasises learning beyond fixed computer laboratories using portable devices. Statements A, B and C correctly describe flexible access, micro-learning and interactive uses of mobile devices. The idea that mobile learning requires desktop labs contradicts the basic definition. Therefore, the option that selects only D as wrong is correct.

Option A:
Option A is incorrect because it marks both A and D as wrong statements. Statement A is central to the concept of mobile learning, highlighting anytime, anywhere access. Misclassifying this accurate statement as wrong makes the option untenable.

Option B:
Option B is correct because it identifies D alone as the wrong statement. It recognises that mobility and portability are fundamental to m-learning. By accepting A, B and C as true, this option reflects current educational uses of mobile devices.

Option C:
Option C is incorrect because it groups A, B and D as wrong. Both A and B correctly describe key benefits of mobile learning, while only D is false. Including true statements in the wrong set invalidates the combination.

Option D:
Option D is incorrect because it treats B, C and D as wrong statements. Statements B and C are accurate, as mobile tools can support micro-learning and in-class quizzes or polls. Mixing these with the false statement D means the combination cannot be correct.

Cascading Style Sheets is a style sheet language that controls how HTML elements are displayed, including fonts, colours, spacing and positioning. It allows developers to separate content from presentation, making web pages easier to maintain and redesign. Rules from multiple style sheets can cascade, determining final appearance based on specificity and order. Thus, the language described in the stem is Cascading Style Sheets.

Option A:
Option A, SQL, is used for managing and querying relational databases and does not influence the visual presentation of web pages.

Option B:
Option B, XML, is a markup language for representing structured data and is not primarily dedicated to styling HTML documents.

Option C:
Option C, PHP, is a server side scripting language used to generate dynamic content but does not itself specify how elements are styled in the browser.

Option D:
Option D is correct because CSS, or Cascading Style Sheets, is explicitly designed to define the look and formatting of HTML documents, as stated in the question.

Statements A, B, D, E and F present a balanced view of ICT in pedagogy. ICT can enable learner-centred and collaborative activities, blended models and multimedia support, and must be purposefully aligned with objectives and assessments. Statement C is false because technology alone cannot guarantee understanding; teacher facilitation remains essential. Therefore all statements except C are correct, so the right combination is A, B, D, E and F.

Option A:
Option A is incorrect because it omits F, ignoring the need to align ICT with objectives and assessment. A, B, D and E are true but do not reflect the full planning perspective required for effective integration.

Option B:
Option B is incorrect because it includes C, which exaggerates the power of ICT by suggesting automatic understanding. Including a false statement renders the whole option wrong even though other statements are correct.

Option C:
Option C is correct because it collects all positive and realistic statements about ICT’s role while excluding the overclaim in C. It recognises that ICT is a tool whose effectiveness depends on thoughtful design and alignment.

Option D:
Option D is incorrect because it omits A and adds no new correct statements. Without A, the emphasis on learner-centred interactivity is missing, and the combination does not contain the complete set of true statements.

Statements A, B and D correctly describe the nature and prerequisites of e-governance, while statement C is false. E-governance utilises ICT to deliver services and interact with citizens, often improving transparency and accountability. It also depends on adequate infrastructure and digital skills among users. Excluding mobile technologies, as claimed in C, contradicts practice because mobile platforms are now central to many e-governance services. Therefore, the combination A, B and D only is correct.

Option A:
Option A is correct because it collects the three statements that match current understanding of e-governance. It recognises the role of ICT in service delivery, the potential for transparency and the importance of citizen readiness. By excluding the incorrect claim about excluding mobile technologies, it reflects realistic e-governance strategies.

Option B:
Option B is incorrect because it includes only A and B and leaves out D. Statement D is also true in emphasising that infrastructure and literacy are essential for effective e-governance. Omitting a true statement makes the option incomplete.

Option C:
Option C is incorrect because it contains B, C and D and thereby accepts C as correct. Statement C wrongly asserts that e-governance does not use mobile technologies, which is inconsistent with many mobile-enabled government services. Including this false statement invalidates the option.

Option D:
Option D is incorrect because it assumes that all four statements are correct. Accepting C would imply that mobile technologies are always excluded, which is contrary to practice. Since one statement is false, the set of all four cannot be the correct answer.

To convert 947 to binary, we divide repeatedly by 2 and track the remainders or use powers of 2. The expansion 947 = 512 + 256 + 128 + 32 + 16 + 2 + 1 corresponds to bits set at those positions. Writing these powers in binary yields 1110110011₂, which is the shortest binary representation without leading zeroes. Therefore, option B correctly represents 947 in binary.

Option A:
Option A corresponds to a binary number slightly larger than 947 because it sets some higher-order bits that increase the value. When its powers-of-two expansion is computed, the sum exceeds 947. Hence, this binary string does not represent the required decimal number.

Option B:
Option C omits some of the powers of two needed to reach 947 and includes a different combination instead. Its positional value expansion produces a smaller decimal number than 947. Thus, it cannot be the correct binary representation of 947.

Option C:
Option B has ones exactly in the positions corresponding to 512, 256, 128, 32, 16, 2 and 1, whose sum is 947. No unnecessary leading zeros are present, so it is a minimum-length form. Every other combination of bits shown in the options changes this sum. Hence, 1110110011₂ is the valid minimal binary representation for 947.

Option D:
Option D rearranges the ones in a different pattern, leading to a distinct combination of powers of two. When expanded, its decimal value is less than 947, so it fails to match the given decimal number. Therefore, it is not the correct binary representation.

Statements A, B, D and E correctly link collaborative tools with academic integrity, while C and F are clearly unacceptable. Shared documents do support group drafting and require proper citation of external sources. Version history aids in tracking who contributed what, and institutional policies clarify boundaries of acceptable collaboration. Claims that plagiarism disappears in shared spaces or that unacknowledged copy-paste is acceptable are false, so any combination including C or F cannot be correct.

Option A:
Option A is incorrect because it omits E, which recognises the importance of institutional policies governing collaboration and plagiarism. While A, B and D are true, they do not fully capture the policy framework within which collaboration occurs. The absence of E makes this combination incomplete as an answer to the question.

Option B:
Option B is correct because it includes all and only the true statements A, B, D and E. It emphasises collaborative drafting, continued need for citation, traceability through version history and the role of policies. By excluding C and F, it rejects the mistaken belief that shared documents remove plagiarism concerns or legitimise unattributed copying.

Option C:
Option C is incorrect because it incorporates C along with otherwise true statements. Statement C falsely asserts that plagiarism is no longer a concern when everyone can edit a document. Including this statement normalises unethical behaviour, so the presence of C invalidates the whole combination.

Option D:
Option D is incorrect because it introduces F and omits A. Statement F condones unattributed copying, which contradicts academic integrity principles. Leaving out A also means ignoring the basic benefit of collaborative tools, so this set cannot be accepted as correct.

Cloud storage providers allocate space on networked servers and present it to users as if it were a drive accessible from many devices. Data stored there can be synchronised, shared and backed up automatically. This model reduces dependence on specific physical devices and supports collaboration. Therefore the services mentioned are instances of cloud storage.

Option A:
Option A, optical media, includes CDs and DVDs that are physical discs and require local drives; they are not internet-based services.

Option B:
Option B, removable storage, refers to USB drives or external disks that are attached directly to computers and do not inherently offer remote, multi-device access.

Option C:
Option C is correct because cloud storage explicitly denotes online file-hosting services where infrastructure is managed by third-party providers and users connect over the internet. The examples given in the stem are among the most widely used cloud storage platforms.

Option D:
Option D, local area storage, is not a standard term in cloud computing and suggests on-premises storage within a network rather than externally hosted services.

Each octal digit represents 3 binary bits because base 8 equals 2³. For a 12-bit binary number, we need 12 ÷ 3 = 4 octal digits to represent all possible combinations. This grouping covers all 12 bits exactly without wasted digits or missing bits. Therefore, the minimum number of octal digits required is 4, which makes option B correct.

Option A:
Option A, 3 octal digits, cover only 9 bits, which is insufficient for 12-bit numbers.

Option B:
Option B is correct because 4 octal digits represent 12 bits exactly (4×3).

Option C:
Option C, 5 digits, cover 15 bits and are not minimal.

Option D:
Option D, 6 digits, cover 18 bits and are far from minimal.

In hexadecimal, the letters A through F represent decimal values 10 through 15. Since 15 is the highest value represented by a single hex digit, it maps to F. Therefore, the hexadecimal representation of decimal 15 is F₁₆.

Option A:
Option A, E, represents decimal 14, which is one less than 15. It is close but not equal to the required value.

Option B:
Option B, D, stands for decimal 13 in hexadecimal notation. This is smaller than 15 and so cannot be correct.

Option C:
Option C, B, corresponds to decimal 11. It is further away from 15 and therefore not suitable.

Option D:
Option D is correct because F is defined as the symbol for decimal 15 in the hexadecimal system. This mapping is standard and widely used in memory and color code representations.

Everyday counting and most written arithmetic activities use the decimal system. This system is based on ten symbols, 0 through 9, and is therefore called a base-10 or decimal system. Historically it is linked to humans having ten fingers, which made grouping in tens natural. Thus, the decimal system is the usual human counting system.

Option A:
Option A is correct because decimal notation underlies standard arithmetic taught in schools and used in currencies and measurements. Its base 10 structure is reflected in common units such as tens, hundreds and thousands. This makes it the default system for human counting.

Option B:
Option B, binary, is primarily used inside digital circuits and computer processors where two distinct states are easy to implement. It is not the system used in ordinary human counting in daily life.

Option C:
Option C, octal, uses base 8 with digits 0 to 7 and is occasionally used as a shorthand for binary. However, it is not the dominant system for general human activities.

Option D:
Option D, hexadecimal, is a base-16 system widely used in computing for compact representation of binary values, but it is not used for routine human counting tasks.

Statements A, B and C correctly distinguish LAN, WAN and MAN by their geographical coverage. LANs serve limited areas like buildings, WANs can span entire countries or continents, and MANs typically cover metropolitan regions. Statement D is false because LANs can be implemented using wired, wireless or mixed technologies. Thus, the combination that includes A, B and C but excludes D is the correct answer.

Option A:
Option A is incorrect because it mentions only A and B as correct and omits C. While A and B are true, statement C is also correct in associating MAN with city-wide networks. Leaving out a true statement means this option does not present the full set of correct statements.

Option B:
Option B is correct because it brings together A, B and C, all of which are accurate descriptions of common network types. It rightly excludes D, which wrongly claims that LANs must always be wireless. Therefore this option aligns with standard ICT classifications of networks by scope.

Option C:
Option C is incorrect because it includes D alongside B and C. Although B and C are true, D is false because LANs may be wired, wireless or a combination. Including a false statement invalidates the combination.

Option D:
Option D is incorrect because it assumes all four statements are correct. Statement D misrepresents the nature of LAN technologies and should not be included among correct statements. A valid answer must exclude that incorrect statement.

One of the key goals of information security is ensuring that data remain accessible when needed, even in the face of hardware failure, accidental deletion or disasters. Backups enable organisations and individuals to restore lost data and resume operations quickly. This directly contributes to the availability and recoverability of information resources. Thus the practice described aligns with the availability and recovery aspect of security.

Option A:
Option A, confidentiality, focuses on preventing unauthorized access to information and is typically achieved through controls like encryption and access permissions rather than simply keeping copies.

Option B:
Option B, authentication, deals with verifying the identity of users or systems and is implemented using passwords, tokens or biometrics. Backups do not by themselves confirm identity.

Option C:
Option C, integrity checking, ensures that data have not been altered in an unauthorized way, often using checksums or hashes; although backups can help compare versions, their primary purpose is not real-time integrity verification.

Option D:
Option D is correct because regular backups are a classic countermeasure to threats against availability, allowing systems to recover data after failures and continue providing services.

A scanner is designed to capture images or printed text and translate them into digital data that a computer can store and process. It uses optical sensors to read the physical document and convert it into a bitmap or similar format. This process is central to digitising paper records and images. Hence, the device described in the stem is a scanner.

Option A:
Option A is correct because standard ICT classifications list scanners as input devices that bring external visual information into the computer system. They play an important role in document management and optical character recognition tasks.

Option B:
Option B, printer, is an output device that produces hard copies of digital documents rather than capturing physical documents into the computer. Its direction of information flow is opposite to what is described.

Option C:
Option C, speaker, outputs audio signals from the computer to the user and therefore cannot be used to input printed text or images.

Option D:
Option D, plotter, produces large-scale drawings or graphics on paper and is considered a specialised output device, not an input device.

Statement D is the only wrong statement because instructional design principles discourage overloading slides with text. Slides should support, not replace, verbal explanation and should be concise. Statements A, B and C correctly describe the benefits and cautions of multimedia use, including combining media types, avoiding overuse of effects and maintaining consistent design. Therefore, the option that chooses only D as wrong is correct.

Option A:
Option A is incorrect because it groups A and D as wrong statements. Statement A is correct in describing how multimedia can integrate different forms of content to enhance understanding. Including this true statement in the wrong set makes the option conceptually unsound.

Option B:
Option B is correct because it isolates D as the sole wrong statement. It acknowledges that text-heavy slides are not recommended and that slides should complement the presenter. By accepting A, B and C as accurate, this option matches good practice in multimedia presentations.

Option C:
Option C is incorrect because it lists A, B and D as wrong statements. Both A and B are valid descriptions of multimedia use and potential distractions. Since only D is actually wrong, this combination misclassifies true statements.

Option D:
Option D is incorrect because it groups B, C and D as wrong statements. Statements B and C are correct in warning against excessive effects and in promoting consistent design. Including them with the false statement D prevents this option from being the right answer.
