III.       Short answer questions.
1. Briefly explain the communication cycle.
Answer: The communication cycle comprises of the following basic elements:
a.   Sender: The sender is the person or entity who wants to send a message and is the source or originator of the communication.
b. Message: This is the information or idea that the sender wishes to convey to the receiver.
c.   Encoding: This refers to the process whereby the sender uses some means like a language or symbols to translate the information in the form of the message.
d.   Channel: Channel is the medium by which the message is sent.
e.    Receiver: The receiver is the person or entity to whom the message is sent.
f.     Decoding: This is the process whereby the receiver interprets and understands the message.
g.    Feedback: The receiver’s response to the message is called feedback.

2.     Why is feedback so important in the process of communication?
Answer: The following are some points that show the importance of feedback in the communication process:
ü Feedback is an integral part of communication process.
ü Feedback makes the communication meaningful.
ü Feedback completes and sustains the communication process.
ü Feedback enables us to evaluate the effectiveness of our message.
ü By analyzing the feedback we can determine whether the communication has produced the desired effect on the receiver or not.

3.     What do you understand by specific and non-specific feedback?
Answer:
Specific feedback: It is a type of feedback that provides detailed or specific information on what the employee did well or poorly. For example, after reading your essay on energy conservation your teacher may say, “You presented all major points related to energy conservation in a logical order with accurate facts and figures. Well done!”
Non-specific feedback: It is a general type of feedback that does not mention the specific reason of the feedback. In the above example, if your teacher had only said, “Well done” or “Good job”, it would have been a non-specific feedback, as it did not specify exactly what was liked about the essay.

5.  4. What is the difference between formative feedback and summative feedback?
      Answer: 
      Formative Feedback: The feedback can be formative. This means that it can be given continuously throughout a year, a session during which time a task is continuing.
       Summative Feedback: Feedback can also be summative. Summative feedback is given at the end of a year or at the end of the duration of the task.
5.   
      5. Give one example each of the verbal and non verbal feedback.
       Answer: 
        Feedback through the voice is called verbal feedback.
        A smile would be a non-verbal feedback.
                                                                (Session-3)     
      1. What is the meaning of communication barriers?
Answer: Anything that makes the message ambiguous or prevents the smooth delivery of the message and /or its reception at the sender’s or the receivers end is called a communication barrier. Communication barriers may arise at any stage of the communication process and create misunderstanding and ambiguity.

2. Explain the environment-based communication barriers with two examples.
Answer: Environment based barriers are also called physical barriers. The major environmental barriers are time, place, space, climate and noise. Some of these are easy to take care of whereas; some may prove to be tough obstacles in the process of effective communication.
Causes of communication barriers:
1.   Lack of trust:  Lack of trust or understanding between the sender and the receiver may act as a communication barrier and hinder the communication between them. Lack of attention, interest, distractions and irrelevance of the messages to the receiver are some other factors that cause communication barriers.
2. Language differences: Language differences and the difficulty in understanding unfamiliar accents are also barriers to communication.
        3. Explain intra-personal communication barriers with the help of a suitable example.
        Answer: There are several factors within ourselves that act as barriers to communication. These are known as the intrapersonal communication barriers. These types of barriers can be our own personality, our attitude, our values, or knowledge etc.
        4. How does the lack of trust affect communication between two parties?
        Answer: Lack of trust or understanding between the sender and the receiver may act as a communication barrier and hinder the communication between them.
        5. Discuss any two measures to over come the barriers in communication.
        Answer: Clarify the ideas before communication: Any message to be communicated to a receiver should be clearly and complete.
        Have clarity in your thoughts: The communicator should be very clear about the objective and what needs to be conveyed to another person.
