Internet of Things (IoT)

Internet of things or IoT is a hot topic nowadays. It’s also being hailed as a disruptive technology. Basically, IoT is a system of interrelated computing devices or things that have the ability to communicate with each other over a network without requiring human interaction.

These things can be anything, ranging from your fan, light or even your wallet. When these things can communicate with each other or with other things , for instance a mobile, this creates an IoT architecture. There are several IoT architectures. The most common one is discussed below:


Here, we have a central cloud or a server, that connects to the things as well as the user. The user can control and monitor through a mobile app or a web based browser. So commands can be sent to the things via the cloud by the user through the app. Similarly, the things can also send status back to the user via the cloud/server. The things could also communicate with each other via server without any app or use control.

So this is a theoretical view of the internet of things. I will be covering the practical implementation of IoT in future posts.
