                 How Data Flow in an IoT System?

                 In an Internet of Things (IoT) system, smart devices and AI work together to collect, process, and use data
                 to make life easier and smarter. The process starts with sensors that collect data from the environment, the
                 user, and smart devices like smartwatches, refrigerators, or cars. This data is then sent to mobile phones,
                 tablets, or other smart devices, which forward it to cloud servers using the internet. In the cloud, the data
                 is processed and analysed to understand what is happening in real-time. The results are shown to the user
                 through notifications, suggestions, or visual displays like graphs and charts. The processed data is also stored
                 safely for future use. Throughout this process, the system tries to understand the context or situation (called
                 context discovery) so that it can provide more accurate and helpful responses. This flow of data and smart
                 decision-making is what makes IoT systems intelligent and useful in daily life.
