When I read anything about the OSI model it always reminds me of this article https://news.ycombinator.com/item?id=26607983 https://news.ycombinator.com/item?id=26607983 > I have said before that I believe that teaching modern students the OSI model as an approach to networking is a fundamental mistake that makes the concepts less clear rather than more. The major reason for this is simple: the OSI model was prescriptive of a specific network stack designed alongside it, and that network stack is not the one we use today. In fact, the TCP/IP stack we use today was intentionally designed differently from the OSI model for practical reasons.
