I've got a secret for you, since several years. I'm a developer and I'm a mess in undestanding 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.
