To better understand this new symbiosis, let's find out what this means and how it all started.

What is IoT and How Does it Work?

The Internet of Things (IoT) is also referred to as the Internet of Everything (IoE). In simple words, the IoT can be described as a network of interconnected devices. Yet, to understand the true nature of it, we need to dive deeper into the concept.

So, what is IoT and how does it work? The IoT consists not of separate devices, but of the whole ecosystem of interconnected gadgets. These devices are equipped with various sensors and processors that allow for information to be collected from surrounding environments and sent over the network. This process happens without any human-to-human or human-to-computer interaction.

The Internet of Things use cases are numerous – from smart thermostats and bulbs, to car trackers, and even health monitors. For example, a thermostat can detect the temperature in a room and send data to the cloud. After that, the data can be sent to an application on the user’s device so that they can decide to either turn the temperature up or down through the app or manually. The system can also automatically perform necessary actions based on predefined user preferences with no human interaction. The latter option is called machine-to-machine (M2M) communication.

IoT devices make our everyday life more comfortable and allow us to automate things that are routine. The next step of their evolution is penetration into other industries, including healthcare. This is where we can speak about the Internet of Medical Things (IoMT).
