What is Communication? Models of Communication
Transmission or process model
This model was dominate
Derived it during 1940s in the Bell Labs
Concerned about communication and ability to communicate well
Tremendous boom after WWII driven by militaries
Coming at it from a mathematical/engineering perspective
Looks at what model suggests
Wanted to make sure appropriate amount of sources were used to be
successful
Can transmit along a channel to a receiver to the destination
Information source is brain, through lungs and vocal cords (transmitter),
noise will travel along channel as sound waves, receiver is ears as we have
the ability to decode it, destination is others brains
Looked as a process of transmitting a message to a receiver
E.g. landline telephone
Information source: person
Transmitter: phone – combination between a microphone and the electronic
system that takes sounds and converts it into electronic signals
Channel: wires
Receiver: second phone
Destination: microphone and speaker to desired contact
E.g. cell phone
Information source: person

Transmitter: phone – message from brain to encode it through texting and
clicking send
Channel: goes through radio satellite
Receiver: another cell phone to decipher it
Noise source: an interference between the 2 speakers (a disruption)
Interferes with message being encoded
Metaphor for anything interrupting to reach destination
Linear and one directional
Doesn’t go straight, could go up and down
Doesn’t have room for the destination to respond
Doesn’t allow for feedback to see if message has been received
Lacking how to conceptualize the content of communications
Noise in regards to computer: pop up ads, poor wifi connection
Shannon and Weavers Three Main Problems in Study of Communication
Technical: How accurately can symbols of communication be transmitted?
Concerned with limited and advantages of a particular medium
Different technical issues while using phone, television, radio
“the medium is the message” – refers to technical constraints of the medium
Semantic: How accurately do transmitted symbols convey desired
meaning?
Misinterpretation of messages
If your using language not understood by audience, it wont be understood

Different words can mean different things in different contents
Meanings that symbols can convey or transmit
Effectiveness: Does the received meaning affect behavior in the desired
way?
Connected to time in which model appears
Issue: one way communication, communication does something to recipient
Makes it look like communication is dominated by propaganda
Is the message being received correctly?
Channel: the physical means by which a signal is transmitted
Medium: The technical or physical means of converting the message into a
signal capable of being transmitted along the channel
Plural of medium is media
Types of Media
Presentational Media
Media that is present
Making the presentation in person being present
E.g. conversation
Representational Media
Re-presents something
Makes something present when it isn’t present
Re-present in different place or time
