Explain the concept of data aggregation in IoT.

• Data aggregation in IoT is the process of deleting data from devices to save storage.

• Data aggregation in IoT is the process of collecting and summarizing data from multiple devices to provide a comprehensive view for analysis and decision-making.

• Data aggregation in IoT is the method of transferring data to a single device for processing.

• Data aggregation in IoT refers to the individual analysis of each device's data without summarization.

What are the challenges of data dissemination in IoT?

• Data storage optimization techniques

• Challenges include limited bandwidth, data privacy, heterogeneous devices, scalability, and real-time processing.

• Unlimited bandwidth availability

• Uniform device compatibility

What are the main components of an Arduino platform board?
