UGC NET Questions (Paper – 1)

When a user visits a website, the browser may save images, scripts and other components in a local cache. On subsequent visits, it can load these elements from the cache instead of downloading them again, reducing bandwidth use and improving loading times. This caching mechanism is a standard ICT technique for optimising user experience on the web.

Option A:
This option correctly describes how caching works: the browser keeps temporary copies of page elements so that later visits are faster and require fewer network requests. This improves performance and reduces bandwidth consumption.

Option B:
This option incorrectly suggests that a browser cache can permanently delete all websites from the Internet. A cache only stores local copies; it has no control over whether sites exist on remote servers.

Option C:
Associating the cache with hardware circuit design confuses software-level optimisation with physical network engineering. Router circuits are designed by engineers, not by browser caching mechanisms.

Option D:
Caching does not prevent pages from being reloaded; it simply affects where elements are loaded from. Users can always refresh pages, and servers can force new downloads when content changes.

SCORM defines how online learning content and LMSs communicate, enabling interoperability and tracking of learner progress across platforms. The acronym expands to Sharable Content Object Reference Model, emphasising the goal of creating reusable learning objects. Many LMSs support SCORM packages for compatibility. Therefore, the correct expansion is Sharable Content Object Reference Model.

Option A:
Option A is correct because official documentation for SCORM explicitly states Sharable Content Object Reference Model as the full form.

Option B:
Option B, Systematic Course Object Resource Method, resembles the acronym but is not the recognised phrase in e learning technology.

Option C:
Option C, Standard Course Online Resource Module, is not used in standards literature and fails to capture the idea of reference model.

Option D:
Option D, Structured Content Object Reuse Mechanism, hints at reuse but does not match the formal name of the standard.

The system that employs symbols 0–9 and A–F contains sixteen distinct digit symbols. A number system with sixteen symbols is called a hexadecimal system. It is widely used in computing to represent binary data compactly. Therefore hexadecimal is the correct name for this base-16 system.

Option A:
Option A is correct because hex means six and deci means ten, together implying sixteen. The symbol set 0–9 and A–F fits exactly with this description. This terminology is standard in computer science.

Option B:
Option B refers to the binary system, which uses only the digits 0 and 1. It has base 2 and not base 16, so it cannot match a system using sixteen symbols.

Option C:
Option C denotes the octal system, which uses digits 0–7 and therefore has base 8. Octal does not use letters A–F as part of its symbol set. Hence it does not fit the description.

Option D:
Option D is the decimal system, which is limited to digits 0–9 and has base 10. It lacks the letter symbols A–F that extend the value range to fifteen.

To convert 101101.011₂ to decimal, we split it into integer and fractional parts. The integer 101101₂ equals 1×32 + 0×16 + 1×8 + 1×4 + 0×2 + 1×1 = 32 + 8 + 4 + 1 = 45. The fractional .011₂ equals 0×1/2 + 1×1/4 + 1×1/8 = 0.25 + 0.125 = 0.375. Adding these gives 45.375. Hence, 45.375 is the correct decimal value.

Option A:
Option A carefully evaluates both the integer and fractional bits to obtain 45.375. It shows correct use of base-2 positional weights, including negative powers for the fractional part. Because both parts sum to 45.375, this option accurately reflects the binary input.

Option B:
Option B, 45.625, would require the fractional part to be .101₂ (0.5 + 0.125) instead of .011₂. Therefore it misinterprets which bits are set in the fractional portion. As a result, it slightly overestimates the correct value.

Option C:
Option C, 45.5, assumes the fractional part contributes only 0.5, which corresponds to .1₂, not .011₂. This ignores one of the lower-order fractional bits and therefore under-represents the actual value of the binary fraction.

Option D:
Option D, 46.375, incorrectly increases the integer part by 1, as if 101110₂ were used instead of 101101₂. This mismatch in the integer component significantly changes the total, so it does not represent the given binary number.

Statements A, B, D and E describe how ICT dashboards support institutional planning. Dashboards aggregate key indicators, visualisation reveals patterns, triangulation checks findings across sources and governance frameworks define how data are managed. Statement C is false because ignoring context can lead to misinterpretation, and F is false since data accuracy should be regularly verified. Thus the correct combination includes A, B, D and E only.

Option A:
Option A is incomplete because it omits E and so does not mention data governance, which is essential for responsible use of dashboards. A, B and D are true but insufficient.

Option B:
Option B is incorrect because it adds F, which wrongly claims that accuracy checks are unnecessary once a dashboard exists. Including this false assumption invalidates the option.

Option C:
Option C is incomplete because it leaves out A and includes only B, D and E. Without A, there is no explicit mention of the dashboard’s role in aggregating institutional data.

Option D:
Option D is correct because it integrates the descriptive, analytic and governance aspects of dashboard use while rejecting simplistic views that ignore context or data quality. It represents a sound approach to data-informed decision-making.

A scanner captures information from physical documents and transmits it to the computer as digital data. This process feeds information into the system rather than sending results out to the user. In classification of hardware, such devices are grouped as input devices. Hence, the blank must be filled with input.

Option A:
Option A is correct because input devices are defined as hardware components used to enter data and instructions into a computer, and a scanner clearly performs this role by digitising paper content.

Option B:
Option B, output, devices such as monitors and printers present processed information to the user and do not capture external data.

Option C:
Option C, storage, devices primarily hold data over time and are not directly involved in acquiring it from outside sources.

Option D:
Option D, processing, refers to components like the CPU that manipulate data but do not acquire it from the external environment.

Statement D is the only wrong statement because open burning or dumping of e-waste releases toxic substances and is not environmentally safe. Statements A, B and C correctly describe what constitutes e-waste, the dangers of improper disposal and the need for recycling and proper management. Sustainable ICT practice emphasises minimising harm through responsible handling of discarded devices. Thus, the option that selects only D as wrong is correct.

Option A:
Option A is incorrect because it labels A and D as wrong. Statement A is true, as e-waste comprises various discarded electronic devices. Including a correct statement in the wrong set makes this combination invalid.

Option B:
Option B is incorrect because it groups B and D as wrong. While D is wrong, B is correct in noting the environmental and health risks of improper e-waste disposal. Mixing true and false statements prevents this option from being right.

Option C:
Option C is incorrect because it lists A, B and D as wrong statements. Both A and B correctly define e-waste and highlight associated hazards, so they should not be treated as wrong. Only D is incorrect.

Option D:
Option D is correct because it isolates D as the sole wrong statement. It reflects the scientific understanding that unsafe disposal practices harm people and ecosystems, and that responsible recycling and management are necessary.

Digital India envisions reliable high-speed connectivity, digital identity, electronic service delivery and widespread digital literacy. These pillars support e-governance and ICT-based education by giving citizens the tools and skills to access resources. By framing digital infrastructure and services as utilities, the mission aims to make technology an integral part of daily life. This goal aligns closely with ICT in education and governance.

Option A:
Option A succinctly captures the three core vision areas often cited for Digital India and relates them to citizen empowerment. It shows how ICT systems form the backbone of modern service delivery and learning.

Option B:
Option B reverses the mission by advocating the closure of online services and a return to purely paper-based processes, which would undermine digital transformation efforts.

Option C:
Option C emphasises entertainment while blocking education, which is inconsistent with public policy objectives aimed at inclusive development.

Option D:
Option D proposes restricting technology use, directly contradicting the aim of digital inclusion and empowerment.

Dividing 2024 repeatedly by 8 yields remainders that form the octal digits 3, 7, 5 and 0, leading to 3750₈. Expanding 3750₈ as 3×8³ + 7×8² + 5×8¹ + 0×8⁰ equals 1536 + 448 + 40 + 0 = 2024. Hence 3750 is the correct octal representation of 2024.

Option A:
3750₈ corresponds exactly to 3×512 + 7×64 + 5×8 + 0 = 2024. This confirms it as the correct octal form of the given decimal number. Its digits reflect the sequence of remainders from the division process.

Option B:
3740₈ represents 3×512 + 7×64 + 4×8 + 0 = 1536 + 448 + 32 = 2016. Since 2016 is less than 2024, this option is not correct.

Option C:
3570₈ equals 3×512 + 5×64 + 7×8 + 0 = 1536 + 320 + 56 = 1912. This decimal value is far from 2024, so the digit pattern is not appropriate.

Option D:
3650₈ gives 3×512 + 6×64 + 5×8 + 0 = 1536 + 384 + 40 = 1960. As 1960 is below 2024, this cannot be the correct conversion.

Encryption converts plaintext into ciphertext using an algorithm and key so that only authorised parties can recover the original information. It safeguards confidentiality when data is stored or transmitted over insecure networks. Modern ICT systems rely heavily on encryption for secure web browsing, email and payment transactions. Therefore the process described is encryption.

Option A:
Option A, compression, reduces the size of data to save bandwidth or storage but does not by itself prevent unauthorised reading. Compressed data is usually easily decompressed without secret keys.

Option B:
Option B, virtualization, refers to creating virtual instances of hardware or operating systems and is unrelated to coding data for secrecy. It addresses resource utilisation rather than confidentiality.

Option C:
Option C is correct because encryption specifically targets security by scrambling data based on cryptographic techniques. Without the appropriate decryption key, intercepted ciphertext should be unintelligible to attackers.

Option D:
Option D, defragmentation, reorganises files on storage media to improve access speed and has no role in preventing others from understanding the content.

Statements A, B, D and E together present a realistic view of ICT-supported administration. Automation can speed up fee processes, timetable tools support complex scheduling, workflows streamline approvals and staff training ensures that systems are used correctly. Statement C is false because automated systems can contain errors and still require verification. Statement F is also false since parallel paper records may be required in some regulatory contexts and are not inherently illegal, so the accurate set is A, B, D and E only.

Option A:
Option A is incomplete because it omits E, overlooking the human factor in successful automation. Even well-designed systems can fail without adequate training and change management. Therefore, A, B and D alone do not capture all the true statements.

Option B:
Option B is correct because it acknowledges both technical tools and the need to build staff capacity. It excludes unrealistic ideas that automation eliminates accuracy checks or automatically bans all paper documentation. As such, it reflects balanced administrative practice.

Option C:
Option C is incorrect because it includes F, implying that maintaining any paper is always illegal. Legal and policy frameworks differ across institutions, and many require some paper documentation, so F is not universally true. This makes the whole combination wrong.

Option D:
Option D is incorrect because it leaves out B, thereby ignoring timetable generation as an important application area of ICT in administration. While A, D and E are correct, omitting B makes the answer incomplete.

To convert 7F₁₆ to decimal, we use positional weights of base 16. The digit 7 is in the 16¹ place and F represents 15 in the 16⁰ place. So the decimal value is 7×16 + 15×1 = 112 + 15 = 127. Therefore, the correct decimal equivalent of 7F₁₆ is 127.

Option A:
Option A, 119, would correspond to a different combination of hex digits because 119 is not 7×16 + 15. It implies an incorrect evaluation of the place values or the value of F. Thus, it underestimates the contribution of the least significant digit.

Option B:
Option B, 125, is close to the correct value but still results from a miscalculation of 7×16 + 15. It might arise from incorrectly adding 112 + 13 instead of 15, showing an error in interpreting F. Hence 125 does not match the precise conversion.

Option C:
Option C correctly applies the base-16 positional rule: 7×16 = 112 and F = 15, giving a total of 127. This option not only uses the right weights but also interprets F as 15, which is crucial in hexadecimal arithmetic. Therefore it is the accurate decimal representation of 7F₁₆.

Option D:
Option D, 129, overshoots the correct value and would imply the least significant digit contributed 17 instead of 15. That is not possible because a single hex digit ranges from 0 to 15. Therefore, 129 cannot be the correct conversion of 7F₁₆.

Statement C is the only wrong statement because modern search engines do not order results simply by alphabetical order of site names. They use complex ranking algorithms based on relevance, content and many other factors. Statements A, B and D correctly describe crawling, phrase searching and advanced filtering capabilities. Hence, the correct option is the one that chooses only statement C as wrong.

Option A:
Option A is incorrect because it groups A and C as wrong statements. Statement A is true since crawlers or spiders are indeed used for indexing pages. Labeling this as wrong contradicts how search engines build their indexes.

Option B:
Option B is correct because it isolates C as the sole wrong statement. It accepts that quotation marks can enforce phrase matching and that advanced search options enable filtering. Recognising C as the only incorrect claim aligns with actual search engine behaviour.

Option C:
Option C is incorrect because it combines A, B and C as wrong statements. Both A and B are accurate descriptions of search engine features, and only C is false. By including true statements in the wrong set, this combination fails.

Option D:
Option D is incorrect because it lists B, C and D as wrong, even though B and D are correct. Phrase searching and advanced search filters are standard features of modern search engines. Mixing correct statements with a wrong one makes the option invalid.

For 321₄, the digits correspond to 3×4² + 2×4¹ + 1×4⁰ = 3×16 + 2×4 + 1 = 48 + 8 + 1 = 57. Therefore, the decimal representation of 321₄ is 57.

Option A:
Option A correctly computes the contributions from each digit using powers of 4. It sums the products to obtain 57, consistent with the rules of base-4 positional notation.

Option B:
Option B, 61, arises from an incorrect addition or mis-weighting of digits and does not match the computed sum.

Option C:
Option C, 45, underestimates the result and suggests one of the digits was underweighted or omitted.

Option D:
Option D, 49, is too small and fails to account for the full value contributed by the highest place.

A uniform resource locator provides a structured way to specify the location and access method for a web resource. It typically includes protocol, domain name and optionally path and query parameters. Browsers use URLs to request the correct resource from web servers. Therefore the web address described is known as a URL, or uniform resource locator.

Option A:
Option A, universal resource number, is not a standard technical term and does not appear in web standards. It loosely resembles the acronym but is incorrect.

Option B:
Option B, unified routing link, again sounds plausible but is not the accepted term in networking or web technologies. It lacks formal recognition.

Option C:
Option C, universal record locator, may suggest a database concept but is not what web protocols specify for addressing resources. It is a distractor.

Option D:
Option D is correct because uniform resource locator is the official name used in standards like RFCs to denote web addresses such as those beginning with http or https. This matches the example provided in the stem.
