Transcript What is Communication?

Welcome to Grade 10
Communications
Technology
…quite possibly the coolest course
you’ll take in high school!

General Computer Lab Policies
No food or drink near computers.
No book bags or coats (leave in your locker if possible).
Internet for school use only.
No games on computers.
Save all work in your folder on the “G” drive. Back-up
work saved on the USB Drives. Work saved elsewhere
will or may be deleted.
Back up your work regularly (save to a USB memory
stick). You’re not the only person using your machine.
Other Things You Should Know…
All equipment must be inspected before use and checked by
your teacher when returned.
Students must sign in and out when working outside the
classroom (ex. video project). You must also list the location
where you will be working in case we need to find you.
Video cameras must be handled with care (they are VERY
expensive). Use proper techniques when filming.
Clean up starts 5 min. before end of class (NO SOONER)!
Failure to treat the room and equipment with respect will
result in a general state of ugliness (you’ll see a side of your
teacher you really don’t want to).
Other Things You Should Know…
Other teachers will likely drop by from time to time,
so be careful. They are relatively harmless, but they
can sense fear. Whatever you do, don’t look them
directly in the eyes (makes ‘em edgy).
Be aware – we are going to make video critics of
each and every one of you. You’ll never be able to
watch TV, movies or animated cartoons the same
way again. Sorry in advance! We cannot be held
responsible for the psychological damage that may
ensue.
Other Things You Should Know…
Comm Tech teachers tend to do not-so-bright things
once in a while, so be patient with us. We are
human after all (or at least that’s the rumor). We,
your teachers, may not always set the best example
so please exercise YOUR better judgment.
Above All.
Treat the class, your classmates and your
teacher with respect and this will be a really
fun semester for everyone!
And now…
Your First “Official”
Comm Tech Note!
Let the games begin!

Universal Systems Model of
Technology
One way of studying the
technological system is by examining
the inputs, processes, and outputs of
that system.
You can think of a communications
system like a car. The gas you put into a car is the
input. When the engine burns the gas, it processes the
"input." When the car moves, you have output.
Universal Systems Model of
Technology
Feedback is an important part of the
process. It allows the sender to know
whether or not the output was
understood correctly by the receiver.
Feedback can take many forms. A
common example would be a person
repeating back what they just heard from
the sender.

What is Communication?
sending and receiving of information
or messages
this text is a message. If you read
and understand the words, you have
received the message and
communication has occurred.
What is Communication?
If this message was written in a
language you couldn't read,
communication would not occur
because you couldn't receive the
message correctly.
Today communication Technology is
used to help people communicate
faster, farther and more often than
ever before.
What is Communication?
It is used to exchange information
with people, machines and animals.
At work people use it to become
more creative and productive.
In school we are using it to learn new
things and to explore our interest and
abilities
What is Communication?
At home we use it to stay
informed, to be entertained and
to keep in touch with family and
friends.
Communication affects nearly
every aspect of our life.
What is Communication?
Just think about what your life would
be like without communication.
No one would speak to you.
There would be no television
no newspaper, or no internet.
No messages would be sent, no
messages would be received.
Why do we communicate?
Humans have basic needs.
Babies cry because they’re hungry.
Food is a basic need for survival,
along with shelter and security.
Communication enables us to meet
our basic needs.
Why do we communicate?
Communication System Model
First their must be a message, it
can be a picture, a sound or the
written word.
Communication System Model
Next, there must be a sender to
“launch” the message.
This message travels through a
communication channel to the
receiver.
Channels can take many forms
(wires, paper, air, etc.).
5 Main Reasons to Communicate
1. To inform (newspapers, news programs).
2. To educate (teachers, journals, newspapers,
textbooks, documentaries).
3. To persuade (ads, salespeople, lawyers).
4. To entertain (huge industry – music, movies,
books, magazines, TV, games, CD-roms).
5. To control (propaganda, machine to machine,
timers, thermostats).
Good exam or test question??
The Communication Process
All messages are designed to reach a specific
AUDIENCE.
Ex. 1 – An ad for retirement planning probably
won’t work well in a magazine for Canadian
teens.
Ex. 2 – Loud hip-hop music may be effective for a
soft drink ad that appears on Muchmusic, but it
wouldn’t be very useful for an insurance ad
during “60 Minutes”.
The Communication Process
We need to consider audience and cost
when designing any form of communication.
Effective communication requires
planning, organization and analysis.
Each of these applies to what you will do in
class, e.g., thumbnails (rough work) –
composite drawing (reworked rough work
in colour)
Modes of Communication
Human-to-human communication: speaking,
gesturing, writing, etc.
Human-to-machine communication:
computers, telephones, musical instruments,
etc.
Machine-to-machine communication: CNC
machines, thermostats, timers, automatic
switches that can sense unsafe conditions
and stop tool motion, etc.
Modes of Communication
Machine-to-human communication: fire
alarms, alarm clocks, gauges, gameboy,
machines that warn of necessary
service or breakdown, etc.
Supplementary types of
communication: ESP, magnet, compass,
etc.
Types of Communication Systems
Data Communication - Computer
systems
Technical Design - Engineering,
architecture and industrial designers....
Optics - Photography, holograms...
Graphic Production - Ink on paper,
plastic metal or fabric...
Audio and Video - Television, radio...
The Problem Solving Method
The Problem Solving Method
This problem solving method is used all of the
time in the area of communication
technology.
Graphic designers use it to develop eyecatching messages
Fiber optic engineers use it to invent new
ways of sending messages. Whether you are
taking photographs, producing a video, or
printing a business cards, there will be
problems to be solved
Congratulations!
You survived your first comm
tech note. Was that so bad?
