Hi,
I've got a secret for you, since several years. I'm a developer and I'm a mess in understanding network things! :'(
It's hard to not understanding things that anyone seems to understand and understanding network concepts can be difficult or time-consuming, specially for developers. That the reason I started to create sketchnotes about Network concepts. I think it could be a good way, more visual, to explain it.
In this first article, let's talk about L4 and L7 layers and OSI model.
As usual, if you like theses sketchnotes, you can follow me, and tell me what do you think. I will publish others sketchs shortly :-).
If you are interested, I already published sketchnotes about Kubernetes, Docker and Istio.

People do tend to forget the difference between L4 & L7 inspite of working with it daily so thanks for the excellent visual notes, Aurelie :)
thanks :)
UDP is another popular protocol that operates in Layer4. So, if you'd like to expand your sketch, you could draw another road for UDP over IP, which in turn could prompt yet another sketch to explain the differences between TCP and UDP.
thanks Fernao, good idea! :-)
Thank you for explaining and also sketchnotes are very nice..
Very sweet
Thanks Majed ♥️
Short but sweet, I like it! I also constantly mismatch / forget the different layers, thanks for the reminder, Aurélie!
me pleasure :-)
Hope you'll like others articles ^^
You should talk about the tcp model as well in comparison to OSI. I believe it has 5 layers instead of the OSIs 7.
Thanks csgeek, I'll think about this point :-)
thanks for this.
