Communication Technology Main Ideas: 1. Information is an essential resource for design (1 of the 7 inputs). 2. Communication technology significantly impacts the way we live. IOT 2-1 POLY ENGINEERING Into which column does each of the technologies below go? Alarm Clock Thermostat Telephone IOT T.V. Remote 2-1 POLY ENGINEERING Into which column does each of the technologies below go? Alarm Clock – communicates the time (with a sound) to a human. Thermostat – measures the temperature and turns the furnace on or off. Telephone – a human speaks in one side, a human hears it on the other. T.V. Remote – a human pushes a button, a signal is send to the television. Into which column does each of the technologies below go? Alarm Clock – communicates the time (with a sound) to a human. Thermostat – measures the temperature and turns the furnace on or off. Telephone – a human speaks in one side, a human hears it on the other. T.V. Remote – a human pushes a button, a signal is send to the television. ASSIGNMENT 1 Instructions: Create the following chart. Fill it in with at least 8 entries in each column. Example technologies are on the next screen. HINT: with any technology, ask yourself what is communicating (human or machine) and what is getting the communication.

POLY ENGINEERING Communication Technology Technology has changed the nature of communication in our society. What are some ways contemporary communication impacts your life? IOT 2-1 POLY ENGINEERING Communication Technology Worldwide market of cell phone users has outstripped all predictions. A world population of 6.9 Billion How many cell phones? First public trials of cell phone use in 2-1 1978 IOT POLY ENGINEERING Cell Phone Users Worldwide At end of 2007: 3.3 Billion 48% of World Population IOT 2-1 POLY ENGINEERING Cell Phone Users Worldwide At end of 2007: Is this exponential or linear? 3.3 Billion Does it look like a line? (It is exponential). 48% of World Population IOT 2-1 POLY ENGINEERING Cell Phone Users Worldwide What is Communication Technology?

IOT 2-1 POLY ENGINEERING Telephone Communication One of the simplest devices in your house What part of this technology system is an example of Human to Machine communication? IOT 2-1 POLY ENGINEERING ASSIGNMENT 2 Example Follows LETTER THIS ASSIGNMENT Radio, T.V., Cell Phone, Internet, GPS, Remote Control For the 6 above technologies analyze the components (the goal, source, encoder, transmitter, receiver, decoder, storage, retrieval, and destination). You will need to research the devices in order to complete this assignment. Provide references. IOT 2-1 POLY ENGINEERING ASSIGNMENT 2 – Example Radio: Goal: Inform Persuade Entertain Control Manage Educate Source: Sounds and Information Encoder: Devices convert sound and info into modulated sine waves Transmitter: Antennas radiate the radio waves into air (medium) Receiver: Antennas capture the radio waves from air Decoder: Devices convert radio waves back into sounds and data [Storage: Recording devices store sounds and data for playback] [Retrieval: Stored data can be accessed and played] IOT Destination: Consumers’ ears and eyes 2-2 POLY ENGINEERING
