For anyone who is interested, the author of this diagram also made a Linux disk I/O diagram (

Shout out to the brilliant and generous work of the author!
Do you know if there is a English version of the book?
If the author agrees, I could try to learn Serbo-Croatian (I'm Polish, good with languages) and translate it to English. I'm kinda a burnout Linux geek, who cannot look at computers much more. Translating a book would be fun, but I would need some sponsoring. Amadeusz at [the old name of icloud].com
