What layer in IoT architecture consists of all hardware components like sensors and RFID tags, crucial for data collection?

  1. Access gateway layer

  2. Edge technology layer

  3. Internet layer

  4. Middleware layer

The correct answer is: Edge technology layer

The edge technology layer is central to the IoT architecture as it includes all the physical hardware components critical for data collection, such as sensors, actuators, and RFID tags. This layer is responsible for gathering real-time data from the environment, which is essential for the functioning of IoT systems. By capturing various environmental parameters, these devices facilitate the initial data input that forms the foundation for further processing and analysis. In contrast, the access gateway layer typically manages the connectivity between the local devices and the internet, ensuring that data collected by edge devices can be transmitted to cloud services or local data processing units. The internet layer primarily focuses on the transmission of data across the network, while the middleware layer handles data management and application services, providing a bridge between data collected by edge devices and the software applications that process that data.
