UGC NET Questions (Paper – 1)

A database management system provides mechanisms for defining data structures, storing records, querying information and enforcing integrity constraints. It is widely used in institutions to manage student records, library catalogues and research data. Because it manages databases rather than just individual files, it is called a database management system.

Option A:
Option A is correct because the phrase database management system matches the acronym DBMS and accurately describes software used to organise and retrieve structured data.

Option B:
Option B, e mail client, handles messages and not general purpose structured datasets.

Option C:
Option C, operating system, manages hardware and other software but does not specialise in database operations.

Option D:
Option D, graphics editor, is designed for image creation and editing, not for tabular or relational data management.

The hard disk drive is a primary form of secondary storage that retains data even when the computer is powered off. It holds the operating system, applications and user files. Whether implemented with spinning platters or solid state technology, it is still referred to as a hard disk drive in common usage. Hence, the correct term for the blank is hard disk.

Option A:
Option A, random access, by itself does not specify a storage device and more often describes the way memory is accessed. It is therefore incomplete and ambiguous.

Option B:
Option B is correct because hard disk drive is the established name for the non volatile storage device described, widely used in ICT literature and everyday practice.

Option C:
Option C, optical, refers to technologies such as CDs and DVDs, which are different categories of storage media.

Option D:
Option D, cache, denotes a smaller, faster memory used to speed up access to frequently used data and does not typically store large amounts permanently.

Statement C is wrong because fabricating or altering data is a serious ethical violation, regardless of the supposed clarity it might bring to conclusions. Statements A, B, D and E are correct: data should be stored securely, retained for reasonable periods, restricted to authorised users and anonymised when appropriate to protect participants. Therefore, C alone is the incorrect statement.

Option A:
Option A is incorrect because it treats C and D as wrong, even though D correctly states that access to identifiable data should be restricted to authorised persons. Including D among wrong statements misrepresents a key confidentiality safeguard.

Option B:
Option B is correct since it singles out C as the only unethical statement and implicitly affirms the ethical principles expressed in A, B, D and E. It highlights that integrity and confidentiality are central to responsible data management.

Option C:
Option C is wrong because it pairs A, which correctly emphasises secure storage, with C, implying both are wrong. This not only fails to isolate the unethical behaviour but also discourages proper data security.

Option D:
Option D is also incorrect because it misclassifies B and D alongside C as wrong, even though B and D describe good practice in data retention and access control. This combination confuses ethical and unethical actions.

Statements A, B, D, E and F cover essential aspects of research data management, while C contradicts good practice. Plans outline processes for collection, storage and sharing, consistent naming improves organisation and access controls protect sensitive data. Metadata and retention rules support reuse and compliance. Avoiding backups purely to save storage is unsafe, so C must be excluded, leaving A, B, D, E and F as the correct set.

Option A:
Option A is correct because it gathers all the statements that align with recognised research data management principles. It addresses planning, organisation, security, documentation and retention obligations. By rejecting C, it also signals that backups are indispensable despite storage costs.

Option B:
Option B is incorrect because it omits F, thereby ignoring legal and ethical considerations in retention periods. Although A, B, D and E are true, leaving out F makes the picture of data management incomplete.

Option C:
Option C is incorrect because it excludes A, which defines what a research data management plan does. B, D, E and F are true, but without A, the role of a formal plan is not acknowledged.

Option D:
Option D is incorrect because it omits B, removing the idea of consistent naming conventions. A, D, E and F are correct, yet overlooking organisation practices makes the answer incomplete.

Statements A, C, D and E are correct and align with ethical standards in data management, whereas B is false. Secure storage protects confidentiality, anonymisation or pseudonymisation reduces re-identification risks and selective reporting of only significant results can seriously bias the literature. Pre-registering analysis plans is one strategy to limit data-driven decisions that distort findings. Statement B is wrong because sharing identifiable data without consent violates privacy and ethical norms.

Option A:
Option A includes A, C and D but omits E, overlooking the role of pre-registration in promoting transparency and reducing bias. Because it leaves out a true statement, this option is incomplete.

Option B:
Option B lists C, D and E but omits A, failing to mention the basic requirement of secure data storage, which is fundamental to confidentiality. As a result, it cannot be considered fully correct.

Option C:
Option C is correct as it gathers together all the true statements and excludes B, which endorses unethical public sharing of identifiable data. It presents a comprehensive view of ethical data handling and reporting.

Option D:
Option D includes B, thereby accepting the idea of sharing identifiable data without consent, which is ethically unacceptable. Even though other statements are true, the presence of B invalidates the option.

Option E also contains B and thus repeats the same ethical error, making the entire combination incorrect.
