## What is Network Handbook?

Network Handbook is an essential app for anyone looking to deepen their understanding of computer networking. Whether you are a student, IT professional, or simply curious, this app offers clear and detailed explanations across eight core networking topics. Explore the OSI Model’s seven layers, learn how TCP/IP powers the internet, and understand DNS and web protocols like HTTP/HTTPS. The app also covers IP addressing, including IPv4 and IPv6, simplifies subnetting, and explains common ports, protocols, and network security fundamentals. Built-in tools like a subnet calculator, a searchable common ports reference, and a network glossary make learning practical and interactive. You can also view your device information directly within the app. Designed for comfortable reading, Network Handbook features a clean dark interface with markdown-formatted content and expandable sections to learn at your own pace. Best of all, it works completely offline, so you can access critical networking knowledge anytime, anywhere.
