HI FRIENDS. In December, I started writing a zine about computer networking! In it, I explain everything that happens when you download this image from the internet, in as much detail as I can fit in 24 pages.
Have you been seeing cool drawings about networking concepts on Twitter from me, and wondering “Julia, I really want to have all of these in one place, how can I get that??“? This is what I was working on!
Here’s the (amazing) cover, by rad programmer Liz Baillie.
This zine explains:
- how packets are put together
- all the steps to download a cat: DNS, sockets, TCP connections, HTTP, and TLS
- networking notation
- networking layers
- what even is a “port”
- and more!
I’m really excited about this – I spent a really long time being confused about how any of this networking stuff worked AT ALL, and I’m hoping this zine will help some people understand a few more things.
Also I am worried about what is happening in the world this week, and I wanted to do a small thing to help.
Read the networking zine today! It’s at https://jvns.ca/zines/#networking-ack.
