IOS Concepts

I am having a hard time understanding the concepts of OSI layers and how the devices maps into different layer. I have read the books and understood to some extend. I am looking for someone who can instill this concepts deep into my mind as a second nature.

Re: IOS Concepts

To gain this understanding, I recommend you read the book called "TCP/IP Illustrated Volume One" by Richard Stevens. This is the definitive book on TCP/IP and really teaches about the OSI model. Granted, the book is a little dated but basic IP protocols (version 4) have not changed that much over the last 10 years. This book is really a great starting point and a MUST READ!
