Computers and smartphones aren't the only devices connecting to the internet. Everyday objects such as lights, televisions, major appliances, cars, and even doorbells are being brought online. The Internet of Things (IoT) refers to the networks of devices and objects that communicate with other devices in the same network via connections to data centers.
What is the Internet of Things?
Although there is plenty of overlap among general technology, cloud computing, and the IoT, pure-play IoT companies are relatively rare. Any company that makes consumer electronics devices, sensors, or chips for industrial or commercial purposes has at least some exposure to IoT technology. Software platforms that manage IoT devices and cloud computing companies are also engaged with the IoT sector.
