4. 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
