In my quest to get my CCNA, I found that I needed something to help me better visualize various concepts. The diagrams in the books are great, but they don’t exactly fit my style of learning, so I’ve come up with a few diagrams of my own. Plus, for me, the process of creating the illustrations helps cement the information in my mind. Hopefully you’ll find them useful as well.
The first one is an overview of the encapsulation de-encapsulation process.
And the second is how Ethernet Frames and IPv4 Packets are encapsulated. Most diagrams show one or the other, but not how both fit together, which I find helpful, so here you go.
For those who like/prefer mindmaps:
I’ll be adding more study helps, including MindMaps, so be sure to check back.
