Why we use OSI reference model and how does the OSI model work in the real world?
Let's say I have made a development board which has a microcontroller, inbuilt bluetooth module, wi-fi module and ethernet module.
When i will send data from board to pc via uart with RS232 interface. Does it come in physical layer?
What can I do with my board, which comes in physical layer and data link layer
