CertMike Explains TCP/IP and the OSI Model 

Absolutely love this guy! I have learned so much from Mike by watching his LinkedIn learning videos and buying his study guide from Amazon. Thanks Mike !

Thank you, I bought your CISSP book and Q/A book, this is the best book on CISSP

Love this video, very clear explanation. The only bit that I wonder about: I thought that the first layer in the TCP model was called the Link layer not the Network Interface Layer?
