Internet of Things (IoT) refers to the network of physical objects embedded with sensors, software, and other technologies that connect and exchange data with other devices and systems over the internet. These objects range from ordinary household items to sophisticated industrial tools. IoT enables these devices to collect and share data, which can be analyzed to gain insights and improve functionality. Common applications include smart homes, wearable devices, industrial automation, and smart cities. IoT devices often use protocols such as MQTT, CoAP, and HTTP for communication, and they may be powered by various technologies like Wi-Fi, Bluetooth, Zigbee, and cellular networks. Security is a significant concern in IoT, as these devices can be vulnerable to hacking and data breaches. Privacy issues also arise, as IoT devices can collect sensitive information about users. Despite these challenges, IoT continues to grow, driven by advancements in technology and increasing demand for connected devices.
