Simply put, IoT is the concept of basically connecting any device with an on and off switch to the Internet (and/or to each other). This includes everything from cellphones, coffee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of. This also applies to components of machines, for example, a jet engine of an airplane. IoT enabled Big Data. The Internet of Things (IoT) consists of all the web-enabled devices that collect, send and act on data they acquire from their surrounding environments using embedded sensors, processors and communication hardware. These "connected" or "smart" devices, can sometimes talk to other related devices and act on the information they get from one another.
