UGC NET Questions (Paper – 1)

The channel in communication is the medium through which the message travels from sender to receiver. Audio-visual tools like slides and microphones carry words,images and sound to students. Therefore in the classroom situation described,these tools function as the communication channel.

Option A:
Noise is any interference that distorts the signal,such as static or background sound; the tools themselves are not noise unless malfunctioning. So this option does not match the role mentioned.

Option B:
Feedback is the receiver’s response returning to the sender,not the physical path of the message. Slides and microphones transmit signals but do not themselves respond,so feedback is incorrect here.

Option C:
The channel can be oral,written,visual or electronic,and audio-visual equipment combines several of these in one medium,which fits the stem well.

Option D:
Context refers to surrounding conditions like physical setting or culture,not to equipment carrying the message. Thus context is not the right completion.

The channel is the medium through which an encoded message travels from sender to receiver. A messaging app carries text,images or audio from the teacher to students. Thus it functions as the channel in this communication situation.

Option A:
The sender is the teacher who creates and sends the notes,not the app itself.

Option B:
The receiver is the student who reads the notes and interprets them. The stem asks about the medium,not the person.

Option C:
The notes themselves are the message that contains content,not the pathway along which they travel.

Option D:
Channel correctly labels the technological path enabling transmission,making it the right completion here.
