In this Class 9 Artificial Intelligence topic from Communication Skills-I, students learn how communication moves from a sender to a receiver through a message and a suitable channel, and how feedback completes the cycle. They explore the roles of encoding and decoding, recognise the importance of context, and see how noise or other barriers can affect meaning. The topic helps them understand clear, effective communication in everyday and AI-related interactions.
Correct answer: D. Communication barrier
Explanation: Poor internet interrupts the channel through which a message is being transmitted. It can delay, distort, or prevent delivery, so it is a communication barrier, specifically a technical barrier. The message is the content, while the sender and receiver are the communicating people.
Correct answer: A. To convey information
Explanation: A message is the information, idea, feeling, or instruction that the sender wants to communicate. Its main purpose is to convey that intended meaning to the receiver through a suitable channel. Increasing noise, removing the channel, or stopping feedback would weaken communication rather than fulfil the message’s purpose.
Correct answer: B. Whether the message was understood
Explanation: Feedback gives the sender information about the receiver’s response. A reply, question, nod, or facial expression may show whether the message was understood, misunderstood, or needs clarification. The channel’s colour, the receiver’s age, and the size of noise do not describe the communicative purpose of feedback.
Correct answer: C. Encoding
Explanation: When a speaker selects a language and particular words, the speaker is encoding an idea into a form that can be sent. The choice should suit the receiver and situation so the meaning is clear. Noise is interference, the receiver interprets the message, and feedback is the later response.
Correct answer: D. Decoding
Explanation: Decoding is the receiver’s process of interpreting the words, signs, or sounds in a message and giving them meaning. Listening and understanding what a speaker intends is therefore decoding. Sending is transmission, encoding is done by the sender, and noise is an interference that may make decoding difficult.
Correct answer: A. Telephone
Explanation: A telephone is a communication channel because it carries a message from the sender to the receiver. In the communication cycle, the channel is the route or tool used to transmit information, such as a telephone, email, letter, or face-to-face speech. A reply is feedback, an idea is part of the message, and a person may be the sender or receiver, so option A is correct.
Correct answer: B. Feedback
Explanation: A nod is a non-verbal response to a message. Depending on the situation, it may communicate agreement, attention, or understanding, so it can function as feedback. It is not the channel carrying the message, the sender who begins communication, or noise that interferes with communication.
Correct answer: D. Ask for clarification
Explanation: If the receiver does not understand a message, asking for clarification is the most effective response. It provides feedback to the sender and gives the sender an opportunity to repeat, simplify, or explain the unclear point. Stopping the conversation leaves the problem unresolved, increasing noise makes understanding harder, and removing the channel prevents communication. Thus, option D is correct.
Correct answer: A. To create and send the message
Explanation: The sender begins the communication process by forming an idea, encoding it into understandable words, signs, or symbols, and transmitting it through a chosen channel. The sender may later receive feedback, but that is not the main role. Creating noise or blocking the channel prevents communication rather than initiating it. Therefore, option A correctly describes the sender’s role.
Correct answer: B. To receive and understand the message
Explanation: The receiver gets the transmitted message and decodes it by interpreting its words, signs, or sounds. The receiver may then provide feedback to complete the cycle. Blocking the message or increasing noise prevents understanding, while choosing the channel is generally part of planning the communication.
Correct answer: C. To deliver the message properly
Explanation: A communication channel is the route or tool used to carry a message, such as speech, a phone call, or email. Choosing a suitable channel helps the message reach the intended receiver clearly and at the right time. The other choices would reduce clarity or interfere with the communication cycle.
Correct answer: A. Channel
Explanation: In this situation, the announcement is the message, the principal or announcer is the sender, and the listening students are receivers. The loudspeaker is the device that carries the sound from the sender to the receivers, so it functions as the communication channel. It is not the content or a person.
Correct answer: B. Sender
Explanation: The principal is the person who prepares and delivers the announcement, so the principal acts as the sender. The announcement itself is the message, the loudspeaker may be the channel, and students who hear it are receivers. Feedback would be a later response from the students, not the principal’s role here.
Correct answer: C. Receiver
Explanation: The students are the people for whom the announcement is intended and who receive its sound and meaning. Therefore, they are receivers. The principal is the sender, the loudspeaker or speech is part of the channel, and noise would be any unwanted sound that makes the announcement difficult to hear.
Correct answer: D. Message
Explanation: The holiday information is the actual content that the announcer wants students to know, so it is the message. The announcer is the sender, students are receivers, and the loudspeaker or spoken announcement is the channel. Identifying the content separately from the people and tool is essential in the communication cycle.
Correct answer: B. Listen or read carefully
Explanation: The receiver should pay attention and listen or read carefully so that the message can be decoded accurately. Focusing on the words and context reduces mistakes and supports useful feedback. Blocking the message or increasing noise prevents understanding; changing the channel is needed only when the existing channel is unsuitable.
Correct answer: C. In an unclear message
Explanation: An unclear message can have more than one possible interpretation, so the receiver may understand a meaning different from the sender’s intention. Clear wording, a suitable channel, and proper feedback reduce this risk. Therefore, the unclear message is the situation in which misunderstanding is most likely.
Correct answer: D. It becomes difficult to understand the message
Explanation: Noise is any unwanted disturbance that interferes with sending, receiving, or interpreting a message. It can make words inaudible, hide important details, or create confusion, so understanding becomes difficult. It does not necessarily shorten the message, change the sender, or produce feedback automatically.
Correct answer: A. Channel
Explanation: In this situation the phone connection, which carries the sound between participants, is not working properly. That makes the communication channel or medium the affected element. The sender, receiver, and topic may still exist, but the message cannot travel clearly through the faulty connection.
Correct answer: C. Communication
Explanation: Communication is the process of sharing or exchanging ideas, information, feelings, or messages between people. It includes a sender, message, channel, receiver, and often feedback. Decoding is only the interpretation stage, noise is an interference, and a symbol is only one possible form of a message.
Correct answer: D. Feedback
Explanation: Feedback gives the sender evidence of the receiver’s understanding through a reply, question, gesture, or expression. Without it, the sender may send a message but cannot confidently judge its effect. The channel carries the message, while noise interferes; neither directly confirms understanding.
Correct answer: A. Visual message
Explanation: A picture communicates through something that can be seen, so information conveyed by it is a visual message. It may use images, signs, diagrams, or symbols instead of spoken words. An oral message depends on speech, noise interferes with meaning, and feedback is a response to a message rather than the picture’s type.
Correct answer: D. The receiver may not understand the message
Explanation: Language should match the receiver’s level and background. If a message uses unfamiliar or very difficult words, the receiver may misinterpret it or fail to understand it, creating a language barrier. Difficult language does not speed up the channel, change the sender, or guarantee positive feedback.
Correct answer: B. Clear message
Explanation: A clear message expresses the idea in words or symbols that the intended receiver can understand. Clarity reduces ambiguity and makes useful feedback more likely. More noise, unnecessarily difficult language, and the absence of feedback can create barriers, so they do not support effective communication.
Correct answer: A. Sender
Explanation: The person who originates, encodes, and sends a message is called the sender. The receiver gets and interprets it, the medium carries it, and feedback is the response. Identifying who begins the communication helps distinguish the sender from the other elements of the cycle.
