Which of the following is a key characteristic of an IoT device?

It can sense its environment and exchange data over a network

It must have a keyboard and screen for user interaction

It requires a constant wired connection to the internet

It must be powered by a battery

A smart building system uses sensors to control lighting and HVAC. The system currently sends all data to a cloud platform for processing. The building manager wants to reduce latency and ensure the system continues to operate if the internet connection fails. Which change should be made?

Increase the cloud platform's processing power

Move processing to a local gateway or edge device
