This article was translated from Japanese by Claude Code.

As a new hire intern (when I was just starting programming), I worked on Java server-side stuff, but recently I’ve been focused solely on app development, so I started reading this book to expand my knowledge in other areas.
What’s Roughly Covered#
As mentioned in the product overview on Amazon, it’s an “introductory book to IT infrastructure centered on servers, networks, and security,” covering a wide range of topics. From CPUs and GPUs to packets, IP addresses, and how network security is ensured. I didn’t reach “I understand it all!” on my first read, so I think I’ll need to revisit and reread it occasionally.
Summary#
For those who studied Computer Science and similar subjects in college, much of the content might be things you already know. But for me, it felt like I could easily learn new things in an understandable way.
