2. What is the Internet of Things? The Internet of Things (IoT) is a vast network of interconnected physical devices, vehicles, home appliances, and other items embedded with sensors, software, and other technologies. These embedded components allow these objects to connect and exchange data over the internet, effectively giving them a "digital life." This connectivity enables them to communicate, collect data, and respond to their environment without direct human intervention, transforming ordinary objects into intelligent entities. Embedded Technology Sensors, software and connectivity components Data Exchange Objects can communicate and share information Intelligence Respond to environment without human intervention Connectivity Interconnected over the internet 2 / 10
