C. The Internet of Things (IoT) is a computing concept. It mainly describes a world where almost every physical object
can be connected and communicate in an intelligent fashion. In other words, with the IoT, the physical world is becoming
one big information system. The IoT is significant because an object that can represent itself digitally becomes something
greater than the object by itself. 26 does the object relate just to you, but is now connected to surrounding objects
and database data.
A thing, in the IoT, can be a person with a heart monitor implant, an automobile with built-in sensors to alert the
driver, or any other natural or man-made object that can be assigned an IP address and provided with the ability to
27 data over a network. For example, we can build bridges with smart cement: cement equipped with sensors to
monitor stresses, cracks, and warpages. This is cement that alerts us to fix problems before they cause a catastrophe. If
there’s ice on the bridge, the same sensors in the concrete will detect it and communicate the information via the wireless
Internet to your car. Once your car knows there’s a 28 ahead, it will instruct the driver to slow down, and if the
driver doesn’t, then the car will slow down for him.
The IoT revolves around machine-to-machine (M2M) communication; it’s built on cloud computing and networks of
data-gathering sensors. It is mobile, virtual, and it provides 29 connection. In the M2M connection, what really
matters is the sensor; the IoT really comes together with the connection of sensors and machines. The real value that IoT
creates is at the intersection of gathering and leveraging data. And the cloud functions as a(n) 30 in place to
analyze the data in real time. The IoT doesn’t function without cloud-based applications to interpret and transmit the data
coming from all the sensors.
