UGC NET Questions (Paper – 1)

The flipped classroom model reverses the traditional sequence of teaching by moving direct instruction to the individual learning space through ICT, such as video lectures. Class time is then used for interactive activities, discussion and application of concepts. This approach leverages technology to free classroom time for higher-order learning tasks. Therefore, the pattern described in the stem is the flipped classroom model.

Option A:
Option A is correct because the term flipped classroom explicitly denotes switching where and how initial content delivery occurs, using ICT tools for out-of-class engagement and in-class active learning.

Option B:
Option B, transmissive, suggests one-way delivery of content from teacher to student and does not capture the restructuring of class and homework roles.

Option C:
Option C, remedial, focuses on support for struggling learners and can be organised in many ways that do not require flipping lecture and practice locations.

Option D:
Option D, examination oriented, refers to focus on test preparation rather than to a specific instructional design pattern involving ICT.

Binary Coded Decimal encodes each decimal digit separately as a 4-bit binary value. This allows decimal digits 0 through 9 to be represented by binary patterns from 0000₂ to 1001₂. Using 4 bits per digit is sufficient and convenient for hardware that interfaces with decimal displays. Therefore, each BCD digit occupies 4 bits.

Option A:
Option A, 3 bits, can represent only 8 distinct values, which is insufficient for ten digits 0 through 9. Thus, 3 bits cannot encode all decimal digits in BCD.

Option B:
Option B, 2 bits, allows only 4 combinations and is even more inadequate. It cannot uniquely represent all decimal digits.

Option C:
Option C is correct because 4 bits give 16 combinations, enough for digits 0–9 and some unused patterns. This is the standard sizing for BCD fields.

Option D:
Option D, 8 bits, would be wasteful for representing a single decimal digit, since 8 bits can represent 256 different values. BCD typically keeps the encoding compact with 4 bits per digit.

An OPAC replaces traditional card catalogues with a computerised interface that users can query by author, title, subject or keywords. It allows faster and more flexible searching for items in the collection. In some systems, the OPAC can be accessed remotely as well. Therefore, its primary function is to support searching the library’s holdings.

Option A:
Automated issue and return of books may be handled by circulation modules or self-check machines, which are separate though related systems. OPAC itself focuses on discovery, not on every circulation function.

Option B:
Playing online games is not an intended academic use of library computers and has nothing to do with catalogue searching. This behaviour does not represent the purpose of an OPAC.

Option C:
This option correctly identifies search as the core service offered by OPAC. It reflects modern practice in ICT-based library management where users locate items via terminals or web interfaces.

Option D:
Changing curricula is an academic governance task and cannot be done simply by interacting with the library catalogue.

Statements A, B and C correctly capture the fundamental relationship between hardware and software in ICT. Hardware is indeed the tangible part of the computer system, while system software like operating systems manages these resources and supports application software. Application software performs specific user tasks such as document creation or computations. Statement D is incorrect because hardware and software are interdependent and must interact for any ICT operation, so the correct combination of true statements is A, B and C only.

Option A:
Option A is incorrect because it recognises only statement A as correct and treats the others as incorrect by omission. While statement A is true, statements B and C are also true descriptions of system and application software. Leaving out B and C makes this option an incomplete and therefore wrong representation of the correct set of statements.

Option B:
Option B is incorrect because it includes only statements A and B. Although both A and B are true, statement C is also a correct description of application software performing user-specific tasks. By failing to include statement C among the correct statements, this option cannot be accepted.

Option C:
Option C is correct because it groups together all and only the true statements, namely A, B and C. These three statements collectively describe how hardware, system software and application software work together in an ICT system. They show the layered structure where hardware is controlled by system software and used by application software to fulfil user needs, while correctly excluding the false statement D.

Option D:
Option D is incorrect because it adds statement D to the otherwise correct group of A, B and C. Statement D is false, as hardware and software must interact closely within any ICT system for processing to occur. Including a false statement alongside true ones invalidates this combination as the correct answer.

Voice over Internet Protocol (VoIP) converts voice signals into digital packets that are transmitted over IP networks. This enables cost-effective voice communication and integration with other data services. Applications like internet calling and video conferencing rely heavily on VoIP technology. Therefore, the communication method described in the stem is VoIP.

Option A:
Option A, circuit switched telephony, refers to traditional public switched telephone networks that establish dedicated circuits for calls rather than using packet networks.

Option B:
Option B is correct because the full phrase voice over internet protocol precisely denotes transmitting voice using IP, which matches the description.

Option C:
Option C, fax over copper, would be an older method for sending documents over telephone lines and does not capture the move to IP networks.

Option D:
Option D, satellite broadcasting, is used to transmit television or radio signals and is not specific to voice calls over IP.

“BY” in Creative Commons licences requires attribution, meaning users must acknowledge the original author. “NC” stands for non-commercial, limiting use to contexts that do not involve direct commercial advantage or monetary compensation. Together, BY-NC licences support wide educational and personal use while restricting commercial exploitation. ICT platforms clearly display these terms so users understand their rights and responsibilities.

Option A:
Option A correctly interprets both parts of the licence code and aligns with official explanations from Creative Commons. It reflects how many educators share resources for teaching but not for resale.

Option B:
Option B ignores both attribution and non-commercial requirements, contradicting the licence conditions.

Option C:
Option C treats the resource as completely closed, whereas BY-NC explicitly allows many forms of reuse.

Option D:
Option D introduces mandatory fees, which are not a built-in feature of BY-NC licences; many such works are freely downloadable.

To convert 1111100111₂ to decimal, we sum the powers of two corresponding to each 1 bit. The pattern represents 2^9 + 2^8 + 2^7 + 2^6 + 2^5 + 2^2 + 2^1 + 2^0. This gives 512 + 256 + 128 + 64 + 32 + 4 + 2 + 1 = 999. Therefore, the decimal value of 1111100111₂ is 999.

Option A:
Option A, 995, is slightly smaller than the correct sum. If we recompute the place values, the total clearly comes to 999, not 995. Hence, this option does not preserve the exact equality required for base conversion.

Option B:
Option B, 997, is also close but still not equal to 999. A correct binary-to-decimal conversion must yield an exact match. Because the powers of two add up precisely to 999, 997 is not the correct result.

Option C:
Option C, 999, coincides exactly with the sum of all relevant powers of two. Both manual expansion and calculator verification confirm this equality. Thus, it is the correct decimal equivalent of the given binary number.

Option D:
Option D, 1001, exceeds the correct value by 2. It would correspond to a different combination of bits in the binary representation. Therefore, 1001 is not consistent with the pattern 1111100111₂.

Statements A and B correctly describe the core purposes of ERP systems in universities, while statements C and D are false. ERP integrates multiple functional areas and automates routine tasks, improving efficiency. It is not designed primarily for entertainment, and reporting is a key feature for decision support, contradicting D. Therefore, the combination A and B only is correct.

Option A:
Option A is incomplete because it mentions integration of processes but ignores the examples of automation given in B. While A is true, it does not alone capture the operational benefits associated with ERP in educational institutions.

Option B:
Option B is correct because it includes both A and B, which together summarise integration and automation roles of ERP systems. It excludes C and D, which wrongly portray ERP as purely entertainment-focused and incapable of reporting. This matches real ICT usage in universities.

Option C:
Option C is incorrect because it adds C to A and B and treats all three as correct. Statement C is clearly false, since ERP is a serious management tool rather than a system for entertainment. Including it makes the combination invalid.

Option D:
Option D is incorrect because it asserts that all four statements are correct, thereby accepting both C and D. As ERP systems are central to institutional management and reporting, these two statements are wrong and invalidate the option.

A search engine is a specialised information retrieval system that indexes web pages and ranks them in response to user queries. By typing keywords, users can quickly find relevant sites, documents and media from billions of resources. Algorithms evaluate relevance using factors like content, links and user behaviour. Hence the description in the stem clearly refers to a search engine.

Option A:
Option A, web browser, is a client program used to display web pages but it does not by itself search the entire web. Browsers can use search engines but their primary purpose is rendering content.

Option B:
Option B, web server, hosts websites and delivers pages to clients but does not provide keyword-based search across the web. Its role is to respond to HTTP requests rather than index external sites.

Option C:
Option C, social network, denotes platforms where users create profiles and interact socially. While they may have internal search features, they are not general tools for locating information across the whole web.

Option D:
Option D is correct because search engines are explicitly designed to respond to keyword queries with ranked lists of web resources, matching exactly what the stem describes.

To convert 45 to hexadecimal, we divide by 16. The quotient is 2 and the remainder is 13. In hexadecimal, 13 is represented by the digit D, so the number becomes 2D₁₆. Therefore, 2D is the correct hexadecimal representation of decimal 45.

Option A:
Option A, 2B₁₆, corresponds to 2×16 + 11 = 43 in decimal, which is less than 45. It has a smaller remainder than needed.

Option B:
Option B, 2C₁₆, equals 2×16 + 12 = 44, still one less than 45. The remainder of 12 does not match the required 13.

Option C:
Option C, 1D₁₆, represents 1×16 + 13 = 29, which is far from 45. It uses too small a multiple of 16.

Option D:
Option D is correct because 2×16 + 13 = 45. The mapping of 13 to D ensures that 2D₁₆ exactly matches the decimal value.

The integer part 100110₂ equals 1×32 + 0×16 + 0×8 + 1×4 + 1×2 + 0×1 = 32 + 4 + 2 = 38. The fractional part .101₂ equals 1/2 + 0/4 + 1/8 = 0.5 + 0.125 = 0.625. Adding both parts yields 38.625. Thus, the decimal equivalent is 38.625.

Option A:
Option A correctly interprets the integer and fractional bits and uses appropriate weights for each bit. The sum 38 + 0.625 = 38.625 is consistent with the structure of the binary number.

Option B:
Option B, 38.75, would require the fractional part to be .11₂ (0.75), which has both first and second fractional bits set. That does not match .101₂.

Option C:
Option C, 38.5, corresponds to a fractional part of .1₂ (0.5), ignoring the contribution of the 2⁻³ bit. This underestimates the true value.

Option D:
Option D, 39.125, suggests both an incorrect integer or fractional part, as 39.125 cannot be obtained from the given combination of bits without changing the pattern.

Base sixteen uses sixteen distinct symbols, typically 0–9 and A–F. This system is widely used in computing to represent binary data compactly. The standard name for the base-16 system is hexadecimal. Therefore, the blank must be filled with the term hexadecimal.

Option A:
Option A correctly names the base-16 system as hexadecimal. This term is the accepted terminology in mathematics and computer science.

Option B:
Option B, octal, refers to the base-8 system, which uses digits 0–7, not sixteen symbols.

Option C:
Option C, decimal, is base 10 and uses digits 0–9 only.

Option D:
Option D, binary, denotes base 2 with digits 0 and 1 only.

An information security policy sets out principles and rules to protect institutional information assets, including data, systems and networks. It covers issues such as user responsibilities, password management, incident reporting and sanctions for misuse. Such policies guide technical and administrative controls to mitigate risks. Therefore, the documents described in the stem are information security policies.

Option A:
Option A, cafeteria, policy would deal with canteen operations and is unrelated to network and password use.

Option B:
Option B is correct because the focus on acceptable use of ICT resources and security incident procedures is central to an information security policy as defined in standards and guidelines.

Option C:
Option C, transportation, policy would cover commute or vehicle regulations and has no connection with ICT networks.

Option D:
Option D, alumni, policy concerns engagement with former students and not security of digital resources.

USB provides a universal plug and play interface for many peripheral devices, simplifying connections and power delivery. The acronym stands for universal serial bus, reflecting its goal of replacing multiple legacy ports with a single serial connection standard. This terminology is used in hardware documentation and ICT textbooks. Therefore, universal serial bus correctly completes the expansion.

Option A:
Option A is correct because universal serial bus is the formal name of the USB standard defined by industry consortiums and technical specifications.

Option B:
Option B, unified storage board, narrows the focus to storage and is not a recognised industry term.

Option C:
Option C, universal system bus, sounds plausible but does not match the wording in hardware standards, which clearly state serial.

Option D:
Option D, user service bus, has no established meaning in computer hardware.

Statement C is the only wrong statement because ICT alone cannot automatically remove inequalities created by differences in access, skills and infrastructure. Statements A, B and D correctly describe realistic limitations such as cost, distraction and the need for teacher training. Even with ICT, learners from disadvantaged backgrounds may still face barriers. Hence, the option that selects only C as wrong best matches the conceptual understanding of ICT limitations.

Option A:
Option A is incorrect because it groups A and C together as wrong statements. Statement A is actually true since the cost of equipment, connectivity and maintenance can prevent effective ICT adoption in some institutions. Treating A as wrong misrepresents a genuine challenge faced in many educational contexts.

Option B:
Option B is correct because it isolates statement C as the sole wrong statement. It acknowledges that digital divide issues are not automatically resolved by simply introducing ICT tools. By accepting A, B and D as true limitations, this option properly identifies the single incorrect claim.

Option C:
Option C is incorrect because it lists B and C as wrong statements. While C is indeed wrong, B is true in pointing out that overuse or misuse of ICT and social media can distract learners. Mixing a correct statement with the wrong one makes this option conceptually inconsistent.

Option D:
Option D is incorrect because it marks A, C and D as wrong. Both A and D are valid statements: cost is a barrier and continuous teacher training is necessary for effective ICT use. Including these true statements in the wrong set prevents this option from being the correct answer.
