The Unit Big Idea
The designed world is the product of
a design process, which provides
ways to turn resources - materials,
tools and machines, people,
information, energy, capital, and
time - into products and services.

Systems Model
 Information and Communication systems follow
the systems model and require inputs,
processes, outputs and feedback.
 Example: Text messaging
 Inputs: a phone, a person operating the
phone, cell phone service, etc.
 Process: transmitting the message using
phone, landlines and/or satellite, phone
 Output: message sent
 Feedback: undeliverable message or
confirmation of message sent

System Components
 Information and communication systems can
be further broken down into the:
 Source
 Encoder
 Transmitter
 Receiver
 Decoder
 Storage
 Retrieval
 Destination

Email Example
 Source: Person typing the message
 Encoder: CPU used to translate the keyboard
strokes to programming language
 Transmitter: Wireless connection, modem,
phone line
 Receiver: router on other
computer

Email Example
 Decoder: CPU used to translate binary code to
software application
 Storage: Inbox, hard drive, server
 Retrieval: Software application which pulls up
email, such as Outlook, gmail, etc.
 Destination: Other person
reads the email

Reflection
 Can you think of other I&C systems and
identify the inputs, process, output and
feedback?
 Can you identify the source, encoder,
transmitter, receiver, decoder , storage,
retrieval , and destination?
