UGC NET Questions (Paper – 1)

Interactive communication is characterised by ongoing feedback and adjustment between participants. In the stem,the teacher listens to students’ questions and changes explanations accordingly. This shows active two-way influence and adaptation. Therefore,the communication is best described as interactive.

Option A:
Ritualistic communication occurs when routines are followed without much concern for meaning,such as formal greetings; it does not describe responsive teaching.

Option B:
Mechanical communication would imply rigid,unthinking transmission of information,which is the opposite of adapting explanations based on student reactions.

Option C:
Interactive communication helps align teaching with learners’ needs,so option C correctly captures the nature of the classroom described.

Option D:
Unidirectional communication suggests one-sided flow without meaningful feedback,which conflicts with the teacher’s active use of student reactions in the stem.

Social media platforms enable users to produce, comment on and exchange content in a networked environment. They emphasise user profiles, follower relationships and interactive features such as likes and shares. These characteristics distinguish them from one-way broadcasting media. Therefore the applications described in the stem are best classified as social media.

Option A:
Option A is correct because the term social media directly encapsulates the social networking and media-sharing functions of platforms like Facebook and Instagram. These sites exemplify the shift toward participatory Web 2.0 environments.

Option B:
Option B, search engine, is focused on information retrieval and does not primarily host user timelines or social interactions, even though some social elements may appear.

Option C:
Option C, operating system, is system software that manages hardware and provides a platform for applications and is quite different from online social platforms.

Option D:
Option D, firmware, is embedded software inside hardware devices and has no resemblance to the interactive websites described.
