Soon every device you own — and nearly every object you can imagine — will be connected to the Internet.
Your refrigerator, smoke detector, doorbell and air freshener may already be. Next, clothes, traffic lights and pedestrian walk buttons — and every part of a factory — and even your home's windows, will all be connected, sharing information to make you healthier, your commute shorter, and everything more efficient.
Technology consulting firm Gartner projects that 6.4 billion connected things will be in use worldwide this year, up 30 percent from last year. And Gartner forecasts that number will grow by more than three times, to nearly 21 billion by the year 2020.
