UGC NET Questions (Paper – 1)

Statements A, B and D give a correct picture of open access journals, while statement C is incorrect. Many open access journals are peer-reviewed and maintain quality standards while offering free access to readers. Creative Commons licences often define how content may be reused. By increasing accessibility, open access can enhance visibility and citations. Therefore, the set A, B and D only is correct.

Option A:
Option A is incorrect because it includes only A and B and leaves out D. While A and B are true, statement D is also correct in explaining the impact of open access on visibility and citations. Excluding D makes this option incomplete.

Option B:
Option B is incorrect because it groups A, B and C as correct, accepting C. Statement C is wrong because peer review and open access are independent decisions; many journals are both open and peer-reviewed. Including C therefore invalidates the combination.

Option C:
Option C is incorrect because it lists B, C and D as correct. Although B and D are true, C is false and claims that open access implies lack of quality control. Any combination that accepts C cannot be the right answer.

Option D:
Option D is correct because it chooses A, B and D, which accurately describe free access, licensing and enhanced visibility. It excludes the misleading idea that open access negates peer review and so matches current scholarly communication practices.

A web browser is client software that sends requests to web servers using protocols such as HTTP and displays the returned pages to users. It interprets HTML, CSS and scripts to render interactive content. Examples include Chrome, Firefox, Edge and Safari. Thus, the type of software described in the stem is a web browser.

Option A:
Option A, web server, is software or hardware that responds to browser requests by delivering web pages, so it operates on the server side rather than on the user's device.

Option B:
Option B is correct because browsers are explicitly designed to access, retrieve and display information from the World Wide Web, matching the description given.

Option C:
Option C, search engine, is an online service that indexes web pages and helps users find content but is accessed through browsers rather than being the client program itself.

Option D:
Option D, firewall, is a security system that filters network traffic and has no direct role in rendering web pages.

Cloud computing means using shared remote resources (servers, storage, applications) on demand over the Internet. Hosting LMS and files in the cloud lets users log in from anywhere without local installation.

Option A:
This describes typical cloud use: remote servers provide applications and storage, accessed via the Internet, scalable and centrally managed.

Option B:
Purely local installation with no networking is the opposite of cloud: no shared online infrastructure or on-demand services.

Option C:
Purely printed notes with no digital component do not use any cloud resources at all.

Option D:
A single offline desktop concentrates everything in one machine and has none of the elasticity or remote access of cloud computing.

The internet is often described as a network of networks because it interconnects diverse networks worldwide using the TCP/IP protocol suite. It enables services such as the World Wide Web, email and file transfer. This global connectivity supports communication, commerce and education on an unprecedented scale. Hence the system described in the stem is the internet.

Option A:
Option A, intranet, refers to a private network within an organisation that may or may not be connected to the wider internet and does not span all sectors and countries.

Option B:
Option B is correct because definitions of the internet explicitly mention its global scope and use of standard protocols to interlink heterogeneous networks. The wide range of participating entities listed in the stem matches the actual composition of the internet.

Option C:
Option C, local area network, is restricted to a small geographic area such as a campus or office building and cannot be equated with the worldwide structure.

Option D:
Option D, personal area network, covers connections among devices close to an individual, such as Bluetooth accessories, and is far smaller in scale than the network described.

Antivirus software scans files and system areas for signatures or behaviours associated with malware such as viruses, worms and Trojans. It can quarantine or delete infected components and often provides real-time protection against new threats. Regular updates keep its detection capabilities current. Therefore the software described in the stem is best identified as antivirus software.

Option A:
Option A, graphics, is concerned with image creation and manipulation and has no function in detecting malicious code. It is unrelated to system protection.

Option B:
Option B, utility, is a broader category that includes maintenance and optimisation tools; although antivirus is a kind of utility, the stem points to a more specific label. Using the general term would not be as precise as naming antivirus.

Option C:
Option C, spreadsheet, is used for numerical calculations and data analysis, not for protecting systems from malware infections.

Option D:
Option D is correct because antivirus programs explicitly target malicious software and are marketed for security purposes, matching the intent described in the question.

A firewall acts as a barrier between trusted internal networks and external networks such as the Internet. It filters incoming and outgoing packets according to defined policies, blocking suspicious or prohibited connections. This reduces the risk of intrusions, data theft and malware spread. The option explains this traffic filtering function accurately.

Option A:
This option correctly highlights inspection and rule based control as the main tasks. It shows that firewalls are preventive measures designed to enforce organisational security policies at network boundaries.

Option B:
Processing speed depends on hardware and system configuration and is not directly increased by installing a firewall. In some cases, heavy filtering may even introduce slight delays.

Option C:
Automated writing of research papers is outside the scope of any security device. Firewalls are concerned with access, not content creation.

Option D:
Converting digital data into printed books is a documentation strategy and has nothing to do with network packet filtering.

Statements A, B and C capture the defining characteristics of synchronous and asynchronous communication. Video conferencing is synchronous because all participants interact in real time, and synchronous communication generally requires participants to be online together. Email is asynchronous because messages can be sent and read at different times. Statement D is wrong because asynchronous communication, by definition, does not require everyone to be online at the same time, so the correct combination is A, B and C only.

Option A:
Option A is correct because it includes precisely the three true statements A, B and C. Together they distinguish real-time interaction in video conferencing from time-shifted interaction in email and highlight that synchronous modes require simultaneous online presence. No false statement is included in this set, which matches the requirement of the question.

Option B:
Option B is incorrect because it restricts the set of correct statements to A and C only, omitting B. Statement B is a correct description of email functioning as an asynchronous communication tool where messages can be read later. Excluding B therefore fails to identify the full set of correct statements about synchronous and asynchronous communication.

Option C:
Option C is incorrect because it includes D along with B and C. While B and C are true, statement D is false as asynchronous communication does not require all participants to be online at the same time. By adding a false statement into the combination, this option cannot be considered correct.

Option D:
Option D is incorrect because it considers all four statements to be correct. Asynchronous communication is explicitly characterised by the absence of a requirement for simultaneous online presence, which contradicts statement D. Including this wrong statement alongside the three true ones invalidates the combination.

SaaS delivers applications over the Internet, with providers hosting and maintaining the software on their servers. Users access the service through thin clients such as browsers and do not manage underlying infrastructure or platform components. A hosted LMS exemplifies this model, as teachers and students simply log in to use its features.

Option A:
This option correctly illustrates outsourced application delivery and the client–server relationship central to SaaS, similar to Google Workspace or hosted LMS platforms widely used in education.

Option B:
This describes an on-premises or Infrastructure-as-a-Service style deployment where the institution manages its own servers and software, so it is not SaaS.

Option C:
Hardware assembly is concerned with building devices, not with cloud-based application delivery over the Internet.

Option D:
Physical book storage in a cupboard is unrelated to cloud computing and does not involve web-delivered software services.

E content encompasses all forms of digital instructional materials that can be accessed via computers or mobile devices, including text, audio, video and interactive applications. It is a key component of ICT based teaching and learning environments. The term emphasises that the content is electronic rather than print based. Thus, the digital resources described are called e content.

Option A:
Option A is correct because e content is widely used in ICT and education policy documents to denote electronic instructional materials.

Option B:
Option B, micro finance, relates to small scale financial services and has no connection with digital teaching resources.

Option C:
Option C, blended finance, is a term from development finance, not from educational technology.

Option D:
Option D, field work, refers to data collection or learning activities conducted in real world settings and is not inherently digital.

Statement B is the only wrong statement because sharing passwords and ignoring privacy settings actually increase vulnerability to cyberbullying and other abuses. A, C and D correctly describe the nature of cyberbullying, steps in reporting incidents and institutional responses. Safe practices emphasise protecting accounts and configuring privacy settings carefully. Therefore, the option that selects only B as wrong is the correct answer.

Option A:
Option A is incorrect because it treats A and B as wrong. A is a standard definition of cyberbullying and should not be classified as incorrect, so pairing it with B misidentifies a correct statement as wrong.

Option B:
Option B is incorrect because it groups B and C as wrong statements. C is correct in recommending preservation of evidence for reporting, so including it among wrong statements contradicts good practice.

Option C:
Option C is correct because it isolates B, the unsafe recommendation, as the sole wrong statement and implicitly recognises A, C and D as accurate. It reinforces the importance of secure behaviour and institutional policies in addressing cyberbullying.

Option D:
Option D is incorrect because it lists A, B and C as wrong, misclassifying both the definition of cyberbullying and the value of evidence. Since only B is actually wrong, this combination cannot be accepted.

In hexadecimal, 9 corresponds to 1001₂ and C corresponds to 1100₂. Combining these 4-bit groups yields 1001 1100₂. Therefore, the binary equivalent of 9C₁₆ is 10011100₂.

Option A:
Option A, 10011010₂, would correspond to hex 9A₁₆, not 9C₁₆, because the last four bits represent 1010₂.

Option B:
Option B, 10010110₂, maps to hex 96₁₆, as the last group 0110₂ equals 6. It does not match C, which is 1100₂.

Option C:
Option C, 10011000₂, corresponds to hex 98₁₆, where the last group 1000₂ equals 8. This again differs from C.

Option D:
Option D is correct because 1001₂ for 9 and 1100₂ for C concatenate to 10011100₂. This is the standard grouping method for hex to binary conversion.

Statements A, B and C correctly describe what databases and DBMSs do in ICT systems. They highlight that databases store structured data, DBMSs manage and control access to it and relational models use tables with rows and columns. Statement D is clearly false because a DBMS is software, not a hardware cupboard for printed documents. Thus the combination A, B and C only is correct.

Option A:
Option A is incorrect because it includes only A and B and omits C. While A and B are true, statement C is also correct in describing relational storage structures. Leaving out C means the option does not capture all the valid statements.

Option B:
Option B is incorrect because it groups A, B and D as correct, thereby accepting D. Statement D completely misrepresents a DBMS, so any combination that treats it as true is invalid.

Option C:
Option C is incorrect because it lists B and C only and leaves out A. Statement A is fundamental in defining a database as an organised collection of data. Excluding this definition makes the combination incomplete.

Option D:
Option D is correct because it selects A, B and C, all of which align with standard database concepts. It correctly excludes D, which confuses software with physical storage and printed documents.

To represent 0 to 255, we need 256 distinct binary codes. The number of patterns provided by n bits is 2^n. Since 2^7 is only 128 and 2^8 is 256, 8 bits are necessary. Thus, 8 bits form the standard byte that exactly represents this range.

Option A:
Option A suggests 5 bits, which give only 2^5 = 32 patterns. These patterns can represent decimal values only from 0 to 31. This is far less than the required upper limit of 255, so this option is not correct.

Option B:
Option B suggests 6 bits, which give 2^6 = 64 patterns. With 64 combinations, the range is only 0 to 63. Because 255 is much larger than 63, 6 bits cannot represent all the required integers.

Option C:
Option C suggests 7 bits, which give 2^7 = 128 patterns. That represents values from 0 to 127. Since 255 is beyond 127, 7 bits still fall short of the needed representation range.

Option D:
Option D uses 8 bits, producing 2^8 = 256 unique patterns. These map naturally to the integers 0 through 255. This makes 8 bits the minimal and correct choice for representing all values in this interval.

The National Digital Library of India aggregates metadata and links to millions of digital resources from different Indian institutions and publishers. It offers a single-window search facility for books, articles, theses and learning objects across disciplines. This initiative supports students, teachers and researchers by making academic content widely accessible. Hence, NDLI is a prominent ICT-based digital library initiative in Indian higher education.

Option A:
This option correctly names NDLI as a national-level digital library project supported by government agencies. Its platform leverages ICT to provide 24x7 access to a variety of academic materials. This scale and integration distinguish it from isolated departmental efforts or informal collections.

Option B:
A random social media page may share information but is not curated or comprehensive enough to serve as a national academic repository. Its content may be informal and unverified, which limits its academic reliability. Therefore, it cannot be equated with a formal digital library initiative.

Option C:
A single notice board with printed circulars is a traditional communication tool and does not exploit ICT for wide dissemination or search. Its scope is limited to local announcements and does not provide integrated access to books and academic resources.

Option D:
A personal blog may contain useful insights and teaching materials but is based on individual initiative. It lacks the breadth, institutional collaboration and standardisation found in national digital library projects. Thus, it is not the correct answer.

To represent an unsigned decimal number N in binary, the minimum number of bits n must satisfy 2^n > N−1. For N = 100, 2^6 = 64 which is less than 100, while 2^7 = 128 which is greater than or equal to 100. Therefore 7 bits can represent all numbers from 0 to 127, including 100, and 6 bits are insufficient. Hence, 7 bits is the smallest bit-length that can encode the decimal number 100 in binary.

Option A:
Option A suggests 6 bits, but 6 bits can represent numbers only from 0 to 63, which does not include 100. Since 100 exceeds 63, 6 bits are not enough to encode it in binary. Therefore, 6 bits underestimate the required capacity.

Option B:
Option B gives 7 bits, and 7 bits can represent values from 0 to 127, easily covering 100. It is also the smallest n such that 2^n ≥ 101, so it is the minimal correct choice. Thus, 7 bits is the correct minimum bit-length for representing 100 in binary.

Option C:
Option C suggests 8 bits, which can represent values from 0 to 255 and therefore can represent 100, but it is not the minimum number of bits required. While 8 bits are sufficient, the question asks specifically for the minimum, making this option excessive. Hence, 8 bits is correct in range but not minimal.

Option D:
Option D suggests 9 bits, which can represent an even larger range from 0 to 511, including 100. However, it is even more excessive than 8 bits and clearly not minimal. Therefore, although 9 bits would work, it does not satisfy the requirement of minimum bit-length.
