What are different layers of the IoT protocol stack? Write the classification of IoT protocols.

Answer»

Internet of Things (IoT) PROTOCOLS are ways of protecting data and ensuring it is exchanged securely between devices via the Internet. IoT protocols define how data is transmitted across the internet. By doing so, they ensure that data being exchanged between connected IoT devices is secure.  

Classification of IoT Protocols-
