UGC NET Questions (Paper – 1)

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 and D correctly illustrate e-governance in higher education. ICT systems support academic and administrative work, online platforms make processes more efficient and transparent, and student information or learning management systems are typical e-governance tools. Statements C, E and F are false because e-governance encourages digital records, still needs human oversight and must respect data security and privacy regulations.

Option A:
Option A is incorrect as it omits D, thus not explicitly recognising student information systems and LMS as key components of e-governance in academic settings.

Option B:
Option B is correct because it brings together A, B and D, the three true statements about ICT-supported processes, efficient online services and typical systems used, while excluding C, E and F, which contradict basic principles of e-governance.

Option C:
Option C is incorrect because it includes C, which claims records must remain only on paper, and therefore misrepresents the digital shift that defines e-governance.

Option D:
Option D is incorrect because it introduces E, which wrongly suggests that human decision-making disappears completely, and therefore misleads about the role of judgement in technology-enabled governance.

Statements A, B, D and E all describe common and recommended features of online examination systems. Randomisation, authentication, time limits and data security are central to maintaining fairness and integrity. Subjective questions can be delivered online and may be graded manually or with rubrics, so C is false. Invigilation or proctoring policies are still needed to address identity and misconduct issues, so F is also false, leaving A, B, D and E as the correct combination.

Option A:
Option A is incomplete because it omits E, which emphasises that secure storage of responses and personal data is a crucial institutional responsibility. Although A, B and D are correct, leaving out E underestimates the importance of privacy and security in online assessment. Therefore this option does not capture all the true statements.

Option B:
Option B is correct because it collects the technical and policy aspects that are widely accepted in online examinations. It includes randomisation, authentication, configurable timing and the need for secure storage, while excluding the extreme claims that online exams cannot host essays or do not require proctoring. This makes it the most accurate representation of the situation.

Option C:
Option C is incorrect because it adds F to an otherwise correct set. Accepting F would imply that once an exam is online, invigilation can be ignored, which contradicts concerns about impersonation, collusion and rule violations. The inclusion of this false statement invalidates the whole option.

Option D:
Option D is incorrect because it relies on B, D, E and F and leaves out A. It also includes F, which is wrong regarding the need for proctoring policies. Missing the explicit mention of randomisation and accepting a problematic statement means this combination cannot be correct.

Encryption transforms plain text into cipher text using algorithms and keys, protecting the confidentiality of information during storage or transmission. Only parties possessing the correct key can reverse the process through decryption. This practice is fundamental to secure communication over public networks. Consequently, the process described is encryption.

Option A:
Option A, decryption, is the reverse operation that converts cipher text back into readable form and does not describe the initial protection step.

Option B:
Option B is correct because encryption is defined as the act of encoding information so that only authorised users can access its content, matching the description in the question.

Option C:
Option C, compression, reduces file size to save space or bandwidth but does not prevent unauthorised reading.

Option D:
Option D, authentication, confirms the identity of users but does not itself convert data into unreadable form.

Encryption uses mathematical algorithms to transform plaintext into ciphertext that appears meaningless without the correct key. This protects the confidentiality of sensitive data as it travels over networks or resides on storage devices. Even if attackers intercept the data, they cannot easily interpret it without decryption keys. Thus, the protective process described in the stem is encryption.

Option A:
Option A, compression, reduces the size of data for efficient storage or transmission but does not intentionally hide the content from unauthorised viewers.

Option B:
Option B is correct because encryption is explicitly defined as encoding information to prevent unauthorised disclosure and is a cornerstone of contemporary ICT security practices.

Option C:
Option C, formatting, prepares storage media or arranges document appearance and does not inherently provide confidentiality.

Option D:
Option D, duplication, involves making copies of data, which can actually increase exposure rather than protect against access.

Statements A, B, D and E accurately reflect the role of e-governance and MIS. A is true because automation of key processes is a central purpose of e-governance. B is true since MIS integrates data to support planning and monitoring. D is true as data security and privacy are essential when handling sensitive information. E is true because dashboards summarise key indicators for leadership. C is false because e-governance generally enhances transparency through traceable records, and F is false since manual or alternative backup mechanisms remain important in emergencies.

Option A:
Option A is incorrect because it excludes E and therefore does not mention how dashboards present data in actionable formats for institutional leaders.

Option B:
Option B is incorrect because it omits A, leaving out the automation of core transactional processes, which is a primary reason for e-governance adoption.

Option C:
Option C is incorrect because it fails to include B and instead focuses only on subsets of statements, thus not capturing the full picture of both decision support and automation.

Option D:
Option D is correct as it brings together A, B, D and E, covering automation, information use, security and dashboards, while rejecting C and F, which wrongly describe e-governance as reducing transparency and eliminating all manual backups.

Statements A, B and D accurately compare cloud and local storage options. Cloud storage relies on remote servers and authenticated multi-device access, while local disks can be used without Internet connectivity. Statement C is incorrect because no system can absolutely guarantee zero risk of data loss or security breaches. Hence, the combination that includes A, B and D but excludes C is the correct answer.

Option A:
Option A is incorrect because it lists only A and B as correct statements and omits D. Statement D is also true, since local disks can be accessed offline, so leaving it out underrepresents the correct information about storage types.

Option B:
Option B is correct because it groups A, B and D, which together provide a balanced view of cloud and local storage. It acknowledges the benefits of remote access and the independence of local drives while not overstating security guarantees. By excluding C, it remains conceptually accurate.

Option C:
Option C is incorrect because it includes only B and D as correct and omits A. Statement A is fundamental in defining cloud storage as use of remote servers. Excluding it results in an incomplete description.

Option D:
Option D is incorrect because it accepts A, C and D together and treats C as true. Statement C overclaims the safety of cloud storage, ignoring potential vulnerabilities and failures, so any option including it cannot be correct.
