For example  when we send message on smart-phone to someone  the message is encoded in the form of
            s and  s and is transmitted through satellite.

           Channel:  hannel is  a medium  through which the information is  transferred. It can be air  oral   wire
            telephone   satellite  e-mail   etc.
           Decoding:  he process of converting encoded information                    OMM NI
           into understandable form is called  ecoding. For example
           when  we  receive  a  message  on  our  smartphone   the
           message  is  decoded  from  the   s  and   s  form  to  the
                                                                         S N       COMMUNICATION           I
           language that we understand.                                                  CYCLE

           Receiver:  eceiver is a person to whom the message is
           directed.
           Feedback:  Feedback  is  a  response  of  the  receiver  after
           perceiving the message. It enables the sender to evaluate                   F
           the effectiveness of the message.


        Importance of Feedback
         hen you wear a new dress and ask your mother  “how am I looking in this dress ”  then your mother replies
        with  the feedback. In communication  feedback is an important part. It is defined as the response given to the
        sender by the receiver.  he feedback makes the sender aware  whether the message is received successfully
        or not  whether the receiver liked it or not  whether the choice of the channel was appropriate or not.

        Specific information in the form of written comments and oral conversation is  descriptive feedback.  his type
        of feedback is often shared by teacher and student in order to help the student improve further.
        Specific feedback provides specific and detailed information and is more focused on a particular topic after
        observation  whereas non-specific feedback is very general as the receiver does not think about the message
        in depth. For example  the expressions such as “good  ob ”  “you did great ”  etc. No feedback is also treated
        as a feedback that indicates agreement of views and ideas.

        Feedback is like a backbone in the entire process of communication. It is important as:
           It shows the receiver is interactive.
           It sustains the communication process.

           It is a basis of measuring the effectiveness of communication.
            ositive feedback motivates an individual to do the task even better.
           Negative feedback helps to improve the task and enhance the performance of the sender.


           BARRIERS IN EFFECTIVE COMMUNICATION

         he process of communication has multiple barriers.  arriers are obstacles or di culties that come in the
        way of communication.  hey are the hurdles or problems which affect the transmission of information
        from the sender to the receiver in the communication process. No matter what the nature of obstacles in
        communication is  all the obstacles are clubbed under a common label  i.e.  “NOIS ”.

        Noise is an undesirable input due to which communication barriers enter the communication process and
        cause distortion of the message.
