The Internet of Things (IoT) is an ecosystem of interconnected physical devices embedded with sensors, software, and network connectivity. These devices collect and exchange data, enabling remote monitoring and control.
In simple terms, IoT devices are everyday objects connected to the internet, such as smart thermostats, fitness trackers, and home appliances. They analyze data to optimize tasks—like a smart thermostat learning user preferences or a fitness tracker providing health insights.
While IoT revolutionizes industries like healthcare, agriculture, and manufacturing, it raises concerns about privacy, security, and data misuse.
