Q & A
What is the Shannon-Weaver model of communication?
-The Shannon-Weaver model, also known as the Shannon Weaver model, is a mathematical model of communication that was created by Claude Elwood Shannon and Warren Weaver in 1949. It is a foundational model in the field of information theory and describes the process of communication as a linear sequence of steps involving a sender, an encoder, a channel, a decoder, and a receiver, with noise as a potential source of interference.
Who are Claude Elwood Shannon and Warren Weaver, and what are their contributions to the field of communication?
-Claude Elwood Shannon was an American mathematician and electrical engineer who laid the theoretical foundations for digital circuits and information theory. He is known for his work on mathematical communication models. Warren Weaver was an American scientist, mathematician, and science administrator, recognized as a pioneer in machine translation and for his role in creating support for science in the United States.
What is the role of the sender in the Shannon-Weaver model?
-In the Shannon-Weaver model, the sender is the information source that initiates the communication process. The sender can be a person or a machine that converts ideas into signals or binary digits, which are then encoded for transmission.
What is the function of the encoder in the communication process?
-The encoder in the Shannon-Weaver model is responsible for converting the ideas or information from the sender into a format that can be transmitted through the channel. This can be in the form of signals, binary digits, spoken or written words, or actions.
Can you describe the channel in the Shannon-Weaver model?
-The channel in the Shannon-Weaver model is the infrastructure that carries the information from the sender to the receiver. It can be a physical medium like cable or electrical wires, or it can be a wireless medium, and it is the pathway through which the encoded message travels.
What is meant by noise in the context of the Shannon-Weaver model?
-In the Shannon-Weaver model, noise refers to any interference or distortion that can disrupt the communication process. It can be physical, such as a car horn in the example provided, or it can be conceptual, such as misunderstandings or misinterpretations of the message.
What is the purpose of the decoder in the communication process?
-The decoder in the Shannon-Weaver model is responsible for converting the received signals back into a format that the receiver can understand. It decodes the message, allowing the receiver to interpret the information that was sent.
Who is the receiver in the Shannon-Weaver model?
-The receiver in the Shannon-Weaver model is the end point of the communication process. It is the person or system that receives and interprets the message. The receiver's role is to understand and act upon the information received.
How does the concept of feedback differ in the initial and modified Shannon-Weaver models?
-In the initial Shannon-Weaver model, there is no concept of feedback, meaning the sender does not receive any information about whether the message was correctly understood by the receiver. In the modified model, which includes the concept added by Norbert Wiener, feedback is introduced, allowing for a more interactive and cyclical communication process.
What is the significance of feedback in the communication process as described in the modified Shannon-Weaver model?
-Feedback in the modified Shannon-Weaver model is significant because it allows for the sender to know whether the message has been correctly understood by the receiver. It enables the communication process to be interactive and cyclical, correcting any misunderstandings and ensuring effective communication.
Can you provide an example from the script that illustrates the Shannon-Weaver model in action?
-In the script, an example is given where Thompson calls his assistant and says, 'Come here, I want to see you.' However, a car horn interrupts the call, and the assistant only hears 'I want.' The assistant's inquiry, 'What do you want, Thompson?' serves as feedback in the communication process, illustrating the elements of the Shannon-Weaver model in a real-world scenario.

Highlights
Introduction to the Shannon-Weaver model of communication, created by Claude Elwood Shannon and Warren Weaver in 1949.
Claude Elwood Shannon was an American mathematician and electrical engineer who laid the theoretical foundations for digital circuits, information theory, and mathematical communication models.
Warren Weaver was an American scientist, mathematician, and science administrator, recognized as a pioneer of machine translation and an important figure in supporting science in the United States.
The Shannon-Weaver model includes the sender (information source), encoder, channel, decoder, receiver, and noise as key elements.
The encoder converts ideas into signals or binary digits, while a person can also encode ideas into spoken or written words or actions.
The channel serves as the infrastructure that transmits information from the sender to the receiver.
Noise is an element that interrupts the communication process.
The decoder is a device that decodes the message and converts received signals into a format the receiver can understand.
The receiver is the endpoint of the communication process, where the message is received.
The initial Shannon-Weaver model lacks a feedback mechanism, which has been criticized for omitting an essential element of communication.
Norbert Wiener added the concept of feedback to the Shannon-Weaver model, transforming it from a linear to a cyclical or interactive model of communication.
The modified Shannon-Weaver model includes the sender, encoder, channel, noise, decoder, receiver, and feedback.
Feedback allows the sender to know if the recipient has correctly understood the message.
Example given: Thompson calls his assistant, but noise from a car horn interrupts the call, leading to a misunderstanding and the need for clarification.
In the example, Thompson is the sender, the telephone is the encoder, the cable or electrical wires are the channel, the car horn is the noise, the assistant's telephone is the decoder, and the assistant is the receiver.
The assistant's question 'What do you want, Thompson?' serves as feedback in the communication process.
The distinction between the initial and modified Shannon-Weaver models is important, as most preferences only include the initial model without a feedback loop.
Encouragement for students to continue learning about communication models.

hello students we will now talk about
the second model of communication the
shannon beaver model this was created by
claude elwood shannon and warren beaver
in 1949
and who are
claude elwood shannon was an american
mathematician and an electrical engineer
who laid the theoretical foundations for
digital circuits and information theory
and mathematical communication model
while warren weber
was also an american scientist and
mathematician and a science
administrator he is widely recognized as
one of the pioneers of machine
translation and as an important figure
in creating support for science in the
united states
they are the proponents of the sun and
beaver model let's have the initial
model developed by shannon and paper
it has the following elements we have
the sender who is the information source
we have the encoder which is a machine
that converts the idea into
signals or binary digits
then we have
however it can be a person also
a person that converts the idea into
spoken or written words or actions and
we have the channel which is an
infrastructure
that gets the information from the
sender and then go there through the
decoder end receiver it is the medium of
communication we also have the element
of noise that interrupts
the communication process a decoder is a
device that decodes the message
and
converts
the
signals the received signals into a
message or into a format that the
receivable will
understand
then the receiver is the end point of
the communication process that is the
time that he or she gets the message
just like the aristotle's model this
model
has no concept of feedback so it has
been criticized for missing
the
essential element feedback without it
the sender will not know whether the
recipient gets the correct context of
the message or net
so
here comes
norbert weiner who added a seven con
concept in the shannon lever model which
changed it from a linear model to a
cyclical or interactive model of
communication
now here is the modified model of
uh shannon weber
weiner added the element of feedback so
from the sender we have the encoder the
channel the noise the decoder the
receiver in
additionally we have feedback
let's have this example thompson called
this assistant and said come here i want
to see you during his call a car
suddenly horned and his assistant only
heard i want the assistant inquired what
do you want thompson
again what are the elements
in the shannon weaver model we have the
sender the encoder the channel the noise
the decoder and the receiver who is the
sender
thomson
our encoder would be the telephone of mr
thomson the channel would be the cable
or the electrical wires
then we have the noise the car horn the
decoder is the telephone used by the
assistant and of course our receiver is
the assistant additionally again we have
the feedback
which is the question from the assistant
what do you want thompson so that is the
feedback
once again the initial model of shannon
weaver and the modified model of shannon
weaver model of communication please
take note of the distinction because
most of the
preferences only include the initial
model of communication which doesn't
have the feedback loop
once again thank you and keep on
learning
