The OSI Model by Example - The Backend Engineering Show with Hussein Nasser

In this episode of the Backend Engineering Show, I’ll explain the OSI Model with an example. I start with the physical layer which is often ignored moved up to the application layer, presentation layer, session layer, transport layer, IP layer, and data link layer. I believe every software engineer should understand the OSI Model as it helps cement the fundamental understanding of networking applications.
