What kind of devices does edge technology primarily focus on in an IoT architecture?

Cloud servers
Data centers
Hardware components
Application servers

The correct answer is: Hardware components

Edge technology in an Internet of Things (IoT) architecture primarily focuses on hardware components that are located at the edge of the network, closer to where data is generated. This includes devices like sensors, gateways, and smart devices that collect, process, and analyze data on-site before sending it to the central data centers or cloud for further analysis. Using hardware components at the edge allows for quicker data processing and reduced latency, enhancing the overall efficiency and responsiveness of IoT systems. This approach is particularly beneficial in scenarios requiring real-time decisions, as it minimizes the need to send all data to a centralized location before action can be taken. In contrast, while cloud servers, data centers, and application servers play significant roles in the broader IoT ecosystem—handling storage, processing, and application hosting—they do not embody the direct operational focus that edge technology emphasizes. Edge computing is all about maximizing the capabilities of the devices that operate in close proximity to the source of data generation.
