Name the three basic layers in the IoT architecture; describe the function of each one, in addition to the technologies and the protocols used.

$$ Then, briefly explain each layer and its role in the IoT architecture. Provide examples of devices or applications that utilize each layer.

$$ Create a diagram or flowchart that illustrates the various layers of IoT architecture and how they interact with each other.

A company launched an IoT$$based application called CureMe for the monitoring and management of healthcare of chronic disease patients in a city. The CureMe application is designed for:

$$ A Personal usage as the mobile platform is capable to generate alerts for caregivers when something goes wrong about the vital sign readings of chronic disease patients

$$ B Government agencies with the provisioning of the web platform to analyze disease trends in the city

Considering the implementation perspective of an IoT system, provide a clear architecture diagram of CureMe application. All five IoT building blocks are required to be shown in this IoT$-$based healthcare architecture diagram. Moreover, working details of all involved components $($for CureMe Application$)$ are required to be explained.
