Connectivity is the method in which an IoT device provides and receives information. The devices are connected to the Internet through Wi-Fi, Bluetooth, cellular network, or LPWAN (low-power wide-area network). The devices provide their data to an IoT Gateway, which acts as a hub that sends and sends data to an edge device for cloud or processing.

In most real -time IoT applications, edge computing is employed so that quick decisions can be made when data is generated. It is beneficial in smart cities, distance healthcare or intelligent traffic management systems.

• Data Analysis

Once data is gathered and sent, it is analyzed and processed to reveal valuable information. Only critical information is employed to identify patterns, provide suggestions, or warn users of emerging issues before they escalate.

Numerous systems employ artificial intelligence (AI) and machine learning (ML) nowadays to make analysis more intelligent and accurate. Such technologies assist with predictive maintenance, energy management, and tracking of customer behavior.

• Graphical User Interface (UI)

The last component of the IoT system is the user interface. It may be a web dashboard or an app on their mobile device that makes it easy for users to manage their smart devices. Users can register their devices, provide commands, track performance, and view reports in real-time using the UI.

This makes it easier for IoT technology to be easily used and managed by anyone, even non-tech experts.
