UGC NET Questions (Paper – 1)

Statement B is the only wrong statement because research shows that digital texts do not always produce deeper comprehension than print in every context. Statements A, C and D correctly identify features and possibilities of digital reading devices and platforms. Adjustable displays, annotation tools and analytics are advantages, but comprehension outcomes depend on task, design and learner characteristics. Thus, the option that selects only B as wrong is correct.

Option A:
Option A is incorrect because it treats both A and B as wrong statements. A is a true description of how digital reading devices can improve readability through adjustable settings. Including this accurate statement among the wrong ones makes the option invalid.

Option B:
Option B is correct because it isolates B as the sole incorrect statement and implicitly accepts the other three as true. It acknowledges that digital reading is not universally superior to print but does offer specific functional advantages. This matches nuanced understandings of ICT in reading.

Option C:
Option C is incorrect because it groups B and C as wrong, even though C is true. Annotation and highlighting tools are standard features of many e-readers and reading apps. Mixing a correct statement with the wrong one undermines this combination.

Option D:
Option D is incorrect because it labels B, C and D as wrong statements. Both C and D accurately describe capabilities of digital reading platforms, such as annotation and analytics. Including them with the false claim in B makes the option incorrect.

An IP address uniquely identifies a device on an IP-based network and allows data packets to be routed correctly. It contains information that helps determine the network and host portions of the address. Both IPv4 and IPv6 formats serve this purpose. Hence the numeric label described in the stem is an IP address.

Option A:
Option A, access server, refers to a machine that provides connectivity or services to clients but is not a numeric label. It can possess an IP address but is a physical or virtual device rather than the address itself.

Option B:
Option B is correct because IP addresses are defined in networking standards precisely as numerical identifiers for interfaces or hosts. Without them, communication using the Internet Protocol cannot be properly directed.

Option C:
Option C, domain alias, relates to human-readable names managed by DNS and may map to IP addresses, but the alias itself is not the numeric label assigned by the protocol.

Option D:
Option D, internet service, is a broad term for facilities provided by an ISP or application and does not denote an addressing scheme.

All four statements accurately describe widely used networking devices in ICT. Hubs do broadcast incoming data to all ports, switches selectively forward frames based on MAC addresses, routers connect and route between networks and modems perform modulation and demodulation for transmission over certain media. Since there is no incorrect statement among A, B, C and D, the combination that includes all four is the only correct answer.

Option A:
Option A is incorrect because it leaves out statement D and includes only A, B and C. Although these three are correct, statement D is also true about modems. Omitting a correct statement means this option does not represent the complete set of correct statements.

Option B:
Option B is incorrect because it restricts the set to B, C and D and omits A. Statement A is a true description of how hubs broadcast traffic. Excluding a correct statement prevents this combination from being fully accurate.

Option C:
Option C is correct because it includes A, B, C and D, all of which are true. Together, they cover the basic behaviours of hubs, switches, routers and modems in network communication. As there is no false statement in the list, selecting all of them is consistent with the question.

Option D:
Option D is incorrect because it includes only A and D and omits B and C. While A and D are true, leaving out two other true statements makes the combination incomplete. A valid answer should include all correct statements, not just a subset.

In two's complement, -1 is obtained by inverting all bits of +1 and then adding 1. For 8 bits, +1 is 00000001. Inverting gives 11111110, and adding 1 yields 11111111. Thus, the pattern 11111111 represents -1 in any fixed-width two's complement system, including 8 bits.

Option A:
Option A, 00000001, is the representation of +1, not -1. In unsigned binary and two's complement, this pattern always denotes a positive value. Therefore, it cannot be used for -1 in 8-bit two's complement.

Option B:
Option B, 10000000, represents the most negative value in 8-bit two's complement. Specifically, it corresponds to -128, derived from -2^(n-1). Because -128 is far from -1, this pattern is not correct for the given decimal number.

Option C:
Option C, 01111111, corresponds to the largest positive value, which is +127 in 8-bit two's complement. All leading bits except the sign bit are 1, making it a high positive integer. Thus, it cannot represent -1.

Option D:
Option D, 11111111, results directly from taking the two's complement of 00000001. It encodes -1 consistently in 8-bit signed arithmetic. This is why all bits set to 1 in two's complement signify -1, making this option correct.

Statements A, B and D present a realistic view of the digital divide, while statement C oversimplifies the situation and is incorrect. The divide involves inequalities in access to devices, networks and skills; income, education and infrastructure are key determinants; and digital literacy shapes meaningful use. Even if everyone owns a mobile phone, disparities in connectivity, affordability and skills may persist, so C must be excluded. Thus, the correct combination is A, B and D only.

Option A:
Option A is incorrect because it lists only A and B and omits D. While A and B are true, statement D is also correct in stressing the importance of digital literacy. Excluding D ignores the usage dimension of the digital divide.

Option B:
Option B is incorrect because it includes A, B and C as correct statements, thereby accepting C. The claim that phone ownership alone dissolves the divide fails to recognise quality, skills and usage gaps. Including this statement invalidates the option.

Option C:
Option C is correct because it combines the three true statements and leaves out the oversimplified one. It reflects a multidimensional understanding of the digital divide, including access, context and capability.

Option D:
Option D is incorrect because it groups B, C and D as correct, accepting C. While B and D are true, incorporating C’s misleading assertion makes the combination wrong.

Statements A, B, C, D and F correctly distinguish communication modes and their integration. Synchronous interactions occur in real time with tools like video chat, whereas asynchronous tools like email and forums allow time-shifted participation. Combining both modes can address varied interaction needs. Statement E is false because blended learning typically uses both synchronous and asynchronous tools, not just one type. Thus all statements except E are correct, so A, B, C, D and F form the right combination.

Option A:
Option A is incomplete because it omits F and does not mention the pedagogical value of combining both modes. A, B, C and D describe the categories but not their integrated use.

Option B:
Option B is incomplete because it leaves out B and therefore does not provide an example of synchronous tools, even though it includes A, C, D and F. Without B, the explanation is less concrete.

Option C:
Option C is incorrect because it omits A and fails to state explicitly that synchronous communication requires simultaneous participation. While B, C, D and F are true, excluding A makes the set incomplete.

Option D:
Option D is correct because it covers definitions, examples and the rationale for mixing communication modes, while excluding the misleading claim that blended courses avoid asynchronous tools.

Statements B, C and D correctly describe typical features of educational cloud storage services, while A is false. Cloud storage is designed to be accessed from multiple authorised devices over the Internet, not restricted to one device. Many services also maintain version history and support shared folders for collaboration. Therefore, the combination B, C and D only is the correct set of statements.

Option A:
Option A is incomplete because it includes only B and C and omits D. While remote storage and version history are important, shared folders for collaborative work are also a central reason institutions adopt cloud storage.

Option B:
Option B is correct because it gathers all three true statements and excludes A, which wrongly claims that access is limited to a single device. It accurately reflects how cloud storage is used for flexible and collaborative educational work.

Option C:
Option C is incorrect because it includes A, B and C as correct and thus accepts A. Since cloud services are typically available across multiple devices, accepting A contradicts the common design of such systems.

Option D:
Option D is incorrect because it assumes that all four statements are correct and therefore accepts the false restriction described in A. This combination misrepresents the multi-device accessibility of cloud storage.

Statements A, B and D capture key features of Learning Management Systems, whereas statement C is incorrect. LMS platforms typically organise learning materials and activities, monitor learner progress and can support both blended and fully online delivery. Many also integrate communication tools to facilitate interaction. Thus, the combination including A, B and D but excluding C is the correct one.

Option A:
Option A is correct because it selects A, B and D as true statements and leaves out C. It reflects the role of an LMS as a comprehensive platform for content delivery, tracking and flexible course design. Since it avoids the incorrect claim in statement C, this option is consistent with actual LMS capabilities.

Option B:
Option B is incorrect because it lists only A and B as correct, omitting D. Statement D is also true because LMS platforms are widely used to manage both blended and fully online courses. Leaving out D means the option does not cover all correct statements.

Option C:
Option C is incorrect because it groups B and C as correct, even though C is false. Many LMS platforms provide robust communication tools for teacher–student and peer interaction. Including C alongside B makes the answer partly wrong and incomplete.

Option D:
Option D is incorrect because it assumes that all four statements are correct. Accepting C would imply that LMSs never have communication tools, which is contrary to how they function in practice. Any correct option must therefore exclude that statement.

Shodhganga is a digital repository maintained by INFLIBNET where Indian universities deposit electronic versions of PhD theses and dissertations. It promotes open access to research and supports academic integrity. ICT infrastructure makes these works widely discoverable. Thus, the repository described is Shodhganga.

Option A:
Option A is correct because Shodhganga is the well known national repository for theses and dissertations in India.

Option B:
Option B, ShodhSindhu, is the e journal consortium and not the thesis repository.

Option C:
Option C, e Vidya, does not correspond to this specific initiative.

Option D:
Option D, GyanSagar, is not the official name of the repository.

Phishing typically involves sending deceptive emails or messages that appear to come from legitimate organisations to trick users into revealing confidential information. It relies on social engineering rather than purely technical attacks. Because it exploits human trust, it is a major ICT security concern. The practice described is accurately termed phishing.

Option A:
Option A is correct because phishing is the established name for fraudulent communication that attempts to lure users into providing sensitive data under false pretences.

Option B:
Option B, hacking, is a broader term covering unauthorised access to systems and may involve technical exploitation, not necessarily deceptive messages as in the question.

Option C:
Option C, debugging, involves finding and correcting errors in software and is a legitimate development activity.

Option D:
Option D, compiling, translates source code into machine code and has nothing to do with fraudulent acquisition of credentials.

Decimal 101 can be expressed as 64 + 32 + 4 + 1, corresponding to 2^6, 2^5, 2^2 and 2^0. This means that in binary the bits for these positions are 1 while others are 0. Writing them in order gives 1100101₂. Thus, 1100101 is the correct binary representation of 101.

Option A:
Option A, 1100011₂, equals 64 + 32 + 2 + 1 = 99 in decimal, which is smaller than 101 and lacks the 4's place contribution.

Option B:
Option B, 1100100₂, equals 64 + 32 + 4 = 100 in decimal and is one less than 101. It misses the 1's bit.

Option C:
Option C is correct because 1100101₂ equals 64 + 32 + 4 + 1 = 101, matching the required decimal value exactly.

Option D:
Option D, 1100111₂, equals 64 + 32 + 4 + 2 + 1 = 103, which overshoots the target. It has an extra 2's bit set.

Flipped classrooms invert the traditional pattern of lecture in class and homework at home. ICT makes it feasible to provide recorded lectures, interactive modules and readings online for self-paced study before class. Classroom meetings can then focus on application, clarification and collaborative tasks. This shift supports active learning and higher-order thinking.

Option A:
Option A correctly illustrates how ICT extends learning beyond classroom walls and frees up in-person time for richer engagement. It aligns with common implementations in universities and schools.

Option B:
Option B describes the traditional teacher-centred lecture approach, which the flipped model explicitly seeks to modify.

Option C:
Option C contradicts the idea of ICT-supported pedagogies; banning technology removes the means for flipping content delivery.

Option D:
Option D limits learning to library spaces and ignores the role of pre-class digital engagement and in-class interaction central to flipping.

Statements A, B and C correctly outline important aspects of email netiquette and safety, whereas statement D is clearly incorrect. A meaningful subject line, avoidance of sharing sensitive data and respectful language are all best practices in email communication. In contrast, attachments from unknown senders can carry malware or phishing attempts and are not automatically safe. Thus, the combination containing A, B and C only is the correct set of statements.

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 emphasising the role of respectful and concise language in email netiquette. Leaving out C means the option does not include all correct statements.

Option B:
Option B is incorrect because it groups A, C and D together as correct. Statement D is wrong, since unknown attachments may contain security threats despite email protections. Including D alongside A and C makes this combination partially false.

Option C:
Option C is correct because it brings together A, B and C, which are all valid guidelines for safe and polite email use. It excludes the dangerous advice in statement D about trusting all attachments. This balance between clarity, caution and courtesy matches recommended email practices.

Option D:
Option D is incorrect because it treats B, C and D as correct, thus accepting D. Although B and C are true, statement D misleads users into ignoring basic security precautions. A correct option must reject that claim.

Statement C is the only wrong statement because symmetric-key encryption requires the same secret key at both ends, not different keys. A rightly states that encryption transforms plaintext into ciphertext using an algorithm and key, B is correct about protecting confidentiality in transit, and D reflects the use of encryption in secure web protocols such as those used for online payments. Therefore the combination that selects only C as wrong is the correct answer.

Option A:
Option A is incorrect because it treats both B and C as wrong. B accurately describes the role of encryption in protecting confidentiality during transmission, so grouping it with the false statement C misidentifies a true property as wrong. This option therefore overstates the set of wrong statements.

Option B:
Option B is correct as it isolates C, which mischaracterises symmetric-key encryption as using different keys. By recognising that A, B and D are standard descriptions of encryption and that only C is false, this option precisely matches the requirement to select the wrong statement(s).

Option C:
Option C is incorrect because it considers A and C together as wrong. A is a fundamental definition of encryption, so including it among wrong statements contradicts basic ICT knowledge. Mixing one false statement with one true statement makes this combination invalid.

Option D:
Option D is incorrect because it treats C and D as wrong even though D correctly notes that secure web protocols rely on encryption. Since only C is wrong, adding D expands the set of wrong statements beyond what the question requires.

The 8-bit pattern 11111111₂ can be grouped into two nibbles: 1111₂ and 1111₂. Each nibble corresponds to the hex digit F (decimal 15). Combining them gives FF₁₆. Therefore, 11111111₂ maps to FF₁₆.

Option A:
Option A correctly uses nibble-to-hex mapping: 1111₂ = F, so 11111111₂ = FF₁₆.

Option B:
Option B, FE₁₆, would correspond to 11111110₂ and thus to decimal 254, one less than the maximum.

Option C:
Option C, F0₁₆, corresponds to 11110000₂, which is decimal 240 and not the full 8-bit maximum.

Option D:
Option D, 0F₁₆, corresponds to 00001111₂, a value much smaller than 11111111₂.
