TCP/IP and OSI Networking Models...

... go together like horse and carriage. or something like that.

There's no doubt the OSI and TCP/IP networking models are important in all aspects related to networking. No matter what platforms, OSI and TCP/IP are a mainstay in the industry and you have to know and understand what it is, for troublshooting purposes, testing purposes, and for cocktail hour discussion.

Here are some notes and multitudes of sources I use to supplement the information I have from my CCNA exam guide:

1.) TCP/IP Model from Wikipedia
2.) OSI Model from Wikipedia
3.) Need I use more sources than the mighty wiki?

For more info, I just go to the bottom of each pages of the above sources and follow additional links.
Of course, it wouldn't be complete without the obligatory, accompanying images:



I kinda like this one cause it has the encapsulation headers on the layers




Here's a comparison of OSI to TCP/IP model
