|Communication only occurs when there is a
successful transfer of information from a sender to a receiver, and that
information is understood. If I speak Gailic to person who only
speaks French, the message could be successfully sent and received.
However, due to the lack of understanding, no means for the receiver to
decode or interpret the intended message, the result is no communication
result in information and data transfer. A desired message from a source
must go through some kind of process in order for that
message to be materialize or received at the desired destination in a
form to be utilized for a larger intent. Sometimes, the output doesn't
exactly match the input due to miscommunications of some sort or
communication breakdown. How many times have we used the words;
"misunderstood", "misinterpreted", or "that's not what I meant"?
As a system, the process must be monitored and controlled in a
manner so that the process can be adjusted to insure the desired output
is achieved. This can be achieved if the results of the monitored
process can cycle feedback back into the process so that process
can make the necessary adjustments. For example check out this little
video on how you can assist in receiving the proper intended message:
(Sometimes the miscommunication is the result of the receiving end,
that is why feedback is so important)
All communication systems
are meant to do at least one of the following:
- Inform - as in news papers, radio
- Educate- through communication via
teachers, documentaries, medical articles and so on people can gain
- Entertain- music, movies, sitcoms
- Persuade - advertising and lobbyist
are examples of this means of communication purpose.
- Control - CNC/CAM, thermostats and
timers are just a couple of examples of such controlling
Communication systems fall under
either living or nonliving (machine) communication. Living
communication happens between animals, animal to animal. Machines can
communicate with other machines, and obviously, as you are using a
computer to do this lesson, people (animals) can also communicate
with machines. So there are really 3 sets of communication systems,
animal to animal, animal and machine, or machine to machine.
Living or animal
communication may be verbal or nonverbal.
Animal communication Humans are animals as well. We
communicate with animals (including ourselves) through emotional
sounds (whimpers and groans) along with gestures (which may be
through facial or body language). We have also developed
sophisticated language, whether verbal speech or non verbal written
language, sign language, or symbols found on labels and signs .
Unlike other animals, we utilize technologies to extend the
capabilities of our bodies to communicate with one another over
distances and to vast numbers in an instant that no other animal
could comprehend. Through the use of news papers, magazines, radio,
television and internet, mass communication
|If we were follow the evolution of
communication technology throughout history,
we would see that communication has evolved at an exponential
rate, just as other technology systems.
Each era marked was marked by radical social change as a result
of technological intervention, whether it be production,
transportation or communication etc; Each category of
technical systems radically shifted direction at approximately
the same time in history largely due to the interdependence they
have for one another. Don't forget that although production tech
systems, communication systems and transportation systems are
separate categories, they are connected. For example; today's
communication technology (CNC, robots, lasers) play a large role
in production systems, as due transportation systems that move
the product. Transportation systems rely on production systems
to produce the vehicles and communication systems to schedule
and monitor things as well.
The significant characteristics that identify the change for
communication systems for each
era are as follows:
||-began with the development of verbal
language-3200BC,and everything leading up to the
printing press of the mid 1400's(a precursor to
trans Atlantic transmission fr. Nfld -1901,Bell's
telephone, radio, television. All of which are
electronic devices that are independent mediums and do
not provide much interaction.
||Computers-1960's, Internet- 19 Computer
and digital capability based technology that permits
multi medium and interactivity. For example; to be able
to watch TV, listen to the radio and write an e-mail all
at once on the same machine.
illustrates the basic components that make up all communication systems.
- The following is an example of living communication system
- Animal & machine communication
People can also communicate with machines not just though using
machines. When you set a thermostat, you tell it what temperature to
keep the room. the thermostat communicates to the furnace when to
turn off and on to maintain that temperature. When you want your
computer to perform a task, you have to make that communication with
your computer through the use of your mouse, keyboard, etc.
Machine to machine People have developed machines ability to
communicate as well. Again, a thermostat monitors the
temperature of the room by a spring that reacts to changes in
temperature, and tells (informs) your furnace when it's time
to turn on or off to control the environment inside your
house . You are also causing different computer components to
communicate as you navigate through this website.
component of any communication system model can be broken into 5 parts :
any message (such as a thought, a sound or an image) that is
converted for the purpose of transmitting. Encoding devices may be a
microphone, cameras, computers, or
even your brain as you encode your thought to be expressed through
voice or on paper.
transmitter- the device or means of
sending the decoded message from sender to receiver
such as electronic transmitters, sometimes with antennas for TV and
radio, recoding heads,
modems, people's use of writing utensils and keyboards, as well as
cameras etc, for the purpose of conveying a message.
is the carrier or the pathway that transports the transmitted
(sometime referred to as the signal). Examples include air, wires,
fiber-optic cables, film,
video and audio tape, as well as paper.
accepts the transmitted encoded message over the particular channel.
Receivers consist of electronic receivers (with antennas for
wireless), modems, VCR, DVD & MP
players, film negatives, your ear, your eyes and so on.
translates the the coded message, that has been received from the
incoming transmission, into an understandable format. Speakers
decode electric signals into sound, monitors and projectors decode
electric messages into light images, your brain decodes
electric signals into thoughts, imagery etc.

So, we can see that people and animals can communicate through
sound/language and sign or body language, and people can communicate to
machines just as machines can communicate to other machines.
Using a basic model and the
situation where you are trying to communicate to a deaf person that
there is something hanging from their nose. You obviously don't want to
touch it. So in this person to person non verbal communication system,
illustrate how you might get your output to match your input.
In an expanded model, identify the components of
the process that would occur when your mother calls you in for dinner.
What evolutionary characteristics of
communication technology were so important that they became some of the identifying factors that clearly separated history
into different eras? In other words, what communication capabilities
changed the world so dramatically that things were never the same again?
Give 4 different examples how communication systems play a big role in
other technology systems.

Communication systems can do a lot more than simply store
information. Information is any collection
of data, static data in storage or to be distributed.
Knowledge on the other hand, is the
application of that information where it is to be processed or put to
use. For example; let's say someone's four wheeler broke down. The
manual that contains parts lists, instructive material and so-on, is
nothing more than a collection of data, information. The four-wheeler
will never get fixed just because it came with a book. But the person
with the help of the book may be able to fix it if they pool that
information with their experience and understanding of mechanics and
