TCP/IP Model Concepts and Protocols

The video tutorial provides an in-depth look at the TCP/IP protocol suite, comparing it with the OSI model. It explains the layers of both models, highlighting the differences and similarities. The tutorial also covers the various protocols associated with each layer of the TCP/IP model, such as HTTP, DNS, and TCP. Additionally, it introduces the concept of Protocol Data Units (PDUs) and their significance in data transmission. The session concludes with an activity to reinforce understanding of the PDU path.
