Several hundreds of millions of devices will be online



Vint Cerf : computer scientist
"I'm anticipating that several hundreds of millions of devices will be online. A lot will be very small things - sensors, for example, for local ambient information such as temperature, humidity and possibly the detection of biohazards. Or they might be used to monitor and control building conditions or security devices."
