Explore the often overlooked upper layers of the OSI model in this informative video. Delve into the functions and real-world applications of the Session, Presentation, and Application layers (5, 6, and 7). Learn how these layers contribute to data transmission between computers, with examples like HTTP cookies and ASCII encoding. Understand why these layers are frequently combined in modern networking models and gain insights into the layers of abstraction in networking. Discover how different protocols like HTTP and FTP implement these layers independently. Perfect for those seeking a deeper understanding of networking fundamentals and data movement through the internet.
