Systems Model q Information and Communication systems follow the systems model and require inputs,

Systems Model q Information and Communication systems follow the systems model and require inputs, processes, outputs and feedback. q Example: Text messaging q Inputs: a phone, a person operating the phone, cell phone service, etc. q Process: transmitting the message using phone, landlines and/or satellite, phone q Output: message sent q Feedback: undeliverable message or confirmation of message sent © 2011 International Technology and Engineering Educators Association, STEM Center for Teaching and Learning™ Foundations of Technology
