Question
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. Identify the component of loT architecture that collects data from loT devices and performs data pre-processing.

Explanation
A gateway is a component of IoT architecture that collects data from IoT devices and performs data pre-processing. A gateway acts as a bridge between the IoT devices and the cloud platform, and it can filter, aggregate, compress, encrypt, or transform the data before sending it to the cloud for storage and analysis. A gateway can also perform edge computing, which means processing the data locally and providing real-time feedback or actions. A gateway can support various communication protocols, such as WiFi, Bluetooth, Zigbee, or cellular, and it can enhance the security and reliability of the IoT system. A gateway is the component that matches the description given in the question.
