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.
