Communication cycle and its elements

Correct answer: D. Continuous two-way exchange

Explanation: Listening is followed by questions and suggestions, so participants are not merely receiving a message; they are responding and contributing new messages. This creates a continuing two-way exchange, with roles changing as different people speak. The example therefore contradicts one-way communication, absent feedback and permanently fixed roles.

Correct answer: A. Sender

Explanation: The sender generally initiates communication by having an idea, purpose or information to share. The sender encodes that idea and prepares the message for transmission. The receiver, feedback and possible noise occur as the message moves through the cycle, so they do not normally begin the basic sequence.

Correct answer: C. Encoding

Explanation: Encoding is the process of changing an idea, feeling or intention into a communicable form such as words, symbols, pictures or gestures. The sender performs this step before sending the message. Decoding is done by the receiver, feedback is the response and noise is anything that interferes with communication.

Correct answer: D. Decoding

Explanation: Decoding is the receiver's process of interpreting the words, symbols, sounds or gestures in a message and assigning meaning to them. Encoding happens earlier when the sender creates the message. The medium carries it and transmission refers to its movement, so neither describes the act of understanding.

Correct answer: A. Channel

Explanation: Email is a channel or medium because it provides the route through which a message travels from sender to receiver. The message is the actual information, the sender creates or sends it, and feedback is the reply. Context is the surrounding situation, so none of these replaces the channel role of email.

Correct answer: B. Feedback

Explanation: The teacher's question is the original communication, and the student's answer responds to it. Therefore the answer is feedback, because it gives the teacher information about the student's understanding or opinion. Although the answer is also a new message in a broader exchange, its function in this situation is specifically feedback.

Correct answer: C. Noise

Explanation: Loud unwanted sound interferes with the signal and makes the spoken message difficult to hear or interpret. In the communication cycle, such interference is called noise, which is a barrier to effective communication. Context describes the situation, feedback is a response and the sender is the person who initiates the message.

Correct answer: D. Feedback

Explanation: Feedback closes the loop by informing the sender about the receiver's response, understanding or need for clarification. A sender, message and channel are also necessary for communication to occur, but without feedback the basic exchange is not confirmed as a complete cycle. Feedback makes communication interactive and measurable.

Correct answer: A. Message

Explanation: The information, idea or feeling that the sender prepares and transmits is called the message. The sender is the person who initiates it, the medium is the route used to carry it and feedback is the receiver's response. Noise interferes with the message rather than being the information itself.

Correct answer: B. Channel

Explanation: The mobile network carries or transmits voice signals between the people taking part in the call, so it functions as the channel. The speakers are the sender and receiver at different moments, their spoken content is the message and their replies are feedback. The network is not the information itself.

Correct answer: C. Decoding

Explanation: A symbol has already been sent, but the receiver assigns it the wrong meaning. The stage in which the receiver interprets words, symbols or gestures is decoding, so the error occurs there. Encoding concerns creating the symbol, transmission concerns carrying it and feedback is the response after interpretation.

Correct answer: D. Inappropriate encoding of message

Explanation: The sender has chosen language that does not match the receiver's knowledge level. Since encoding means converting an idea into understandable words or symbols, unsuitable vocabulary is inappropriate encoding for this audience. A channel is present, feedback is not excessive and the receiver's location alone does not explain the misunderstanding.

Correct answer: A. Verbal communication

Explanation: The teacher is expressing ideas through spoken words, so the communication is verbal. Students may also observe gestures or visual aids, but those additional cues do not change the main form described in the question. It is not written-only, and it cannot be classified as only non-verbal when speech is the stated method.

Correct answer: B. Purpose of communication

Explanation: Before composing a message, the sender should know the purpose: to inform, request, instruct, persuade or achieve another goal. This decision helps determine what to say, how to say it and which channel to use. Feedback comes later, while medium cost and room size are not the first defining consideration.

Correct answer: C. Letter

Explanation: A letter carries information in written words, so it can serve as the medium for a written message. A gesture, facial expression and eye contact are non-verbal cues used mainly in direct interaction. They may support communication, but they are not the clearest answer when the question specifically asks for a written medium.

Correct answer: B. Technical noise

Explanation: Poor internet interrupts the transmission of sound between the sender and receiver. This is a technical barrier, also called technical noise, because the problem is caused by the network or device rather than by the meaning of the message. Message clarity, feedback, and context do not describe the internet failure itself.

Correct answer: D. The message was not understood correctly

Explanation: When a student performs a different task from the one requested, the instruction was probably misunderstood or interpreted incorrectly. The student’s action provides feedback about the result of communication. It does not prove that the message was successful, that no channel was used, or that feedback is always correct.

Correct answer: A. So the message can be made understandable

Explanation: A sender should adapt vocabulary, examples, detail, and pace to the receiver’s knowledge level. This makes the message easier to understand and reduces the chance of confusion. A suitable message need not be long, the channel may sometimes need changing, and effective communication should encourage rather than prevent feedback.

Correct answer: B. Medium

Explanation: The correct answer is Medium. In communication, the medium or channel is the means used to transmit a message from the sender to the receiver. Here, the announcement is the message and the loudspeaker carries or broadcasts it to listeners. Feedback is the receiver’s response, decoding is interpreting the message, and context is the surrounding situation, so none of those describes the loudspeaker.

Correct answer: C. Feedback has been given

Explanation: A question sent back by the receiver is feedback because it responds to the original message. It may also show that the receiver needs clarification or wants to check understanding. Asking a question does not by itself prove that noise has ended, that the context changed, or that the original sender changed.

Correct answer: D. Language barrier

Explanation: When the sender and receiver do not share a language or understand words differently, the message may not be decoded correctly. This is a language barrier, a communication barrier related to words and meaning. A physical barrier involves space or surroundings, a technical barrier involves equipment or networks, and a visual channel is a medium, not a barrier.

Correct answer: A. Sender

Explanation: The student who creates and sends the birthday invitation is the sender. The friend who receives and reads it is the receiver, while the phone, app, or message service may act as the channel. Noise would be anything that interferes with delivery or understanding. Therefore, the student’s role is sender.

Correct answer: B. Feedback

Explanation: The friend’s confirmation is a reply to the invitation, so it is feedback in the communication cycle. It tells the sender how the receiver has responded to the message. Context is the situation surrounding communication, encoding is converting an idea into words or symbols, and noise is anything that disturbs communication.

Correct answer: C. The chance of misunderstanding decreases

Explanation: A brief and clear message focuses attention on the important information and makes the intended meaning easier to understand. As a result, the receiver is less likely to interpret it incorrectly. Conciseness does not require the sender to speak more, does not stop feedback, and does not make the chosen channel useless.

Correct answer: D. The message will not reach the intended receiver

Explanation: Sending a message to the wrong number creates an addressing or receiver-selection error. The intended receiver may never receive the information, so the communication cannot achieve its purpose even if the wording is clear. It does not improve encoding or guarantee quick feedback; the message may reach a different person or nowhere useful.
