IOT POLY ENGINEERING 2-1 Into which column does each of the technologies below go? Telephone T.V. Remote Alarm Clock Thermostat

Into which column does each of the technologies below go? 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. Alarm Clock – communicates the time (with a sound) to a human. Thermostat – measures the temperature and turns the furnace on or off.
