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

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?
