Bob has secretly installed smart CCTV devices (loT devices) outside his home and wants to access the recorded data from a remote location. These smart CCTV devices send sensed data to an intermediate device that carries out pre-processing of data online before transmitting it to the cloud for storage and analysis. The analyzed data is then sent to Bob for initiating actions.

Answer: C

Explanation:

In the context of IoT architecture, the component that collects data from IoT devices and performs data preprocessing is typically referred to as a Gateway. This device acts as an intermediary between the IoT devices and the cloud infrastructure. It is responsible for aggregating data, performing initial processing, and then transmitting the data to the cloud for further storage and analysis. Gateways are crucial for reducing latency, providing local data buffering, and ensuring that only necessary data is sent to the cloud, thereby optimizing network and storage resources.
