The following are the most important features of IoT on which it OPERATES: 

• Connectivity: Connectivity is the most important aspect of IoT. The IoT ecosystem (i.e. sensors, compute engines, DATA hubs, etc.) cannot operate properly without seamless communication among the interrelated components or objects. There are many ways to connect IoT devices including radio waves, Bluetooth, Wi-Fi, and Li-Fi.
• Analyzing/Sensing: Once all the relevant things are connected, the next step is to analyze data that is being collected and use it to build effective business intelligence. It is very important to extract knowledge from the generated data. A sensor, for example, generates data, but those data won't be of much use unless they are INTERPRETED properly by us.
• Active Engagements: A lot of today's interactions with connected technology occur via passive engagement. Through IoT, multiple products, cross-platform technologies, and services work together on an active engagement basis. The use of cloud computing in blockchain enables active engagements among IoT components in general.
• Scalability: Each DAY, more and more elements are connecting to the IoT zone. IoT setups should therefore be able to handle massive expansion. The data generated as a RESULT is immense, and it should be handled correctly.
• Artificial Intelligence: The IoT essentially makes things such as mobile phones, wearables, vehicles, etc., smart and enhances life by making use of data collection, artificial intelligence algorithms, and networked technologies. For example, if you have a coffee machine whose beans are going to end, it will order coffee beans from the retailer of your choice.
