ICT noise in communication – UGC NET Question

Noise in communication theory refers to any interference that distorts the message as it travels from sender to receiver. In ICT contexts, this may include electrical interference, data corruption or irrelevant on screen distractions. Noise reduces the effectiveness of communication by obscuring intended meaning. Thus, the disturbances described are known as noise.

Option A:
Option A is correct because noise is the standard term used in communication models to denote unwanted disturbances in the channel.

Option B:
Option B, redundancy, can sometimes help overcome noise by repeating information and is not itself a disturbance.

Option C:
Option C, protocol, defines rules for communication and is not a form of interference.

Option D:
Option D, feedback, is a response from the receiver to the sender and contributes to clarity rather than causing distortion.
