Namaste Computer Networks — Complete Tutorial Index

Hey everyone! Welcome to Namaste Computer Networks! 🙏

Every time you load a page, send a message, or hit an API, a small miracle happens: data hops across routers, oceans, and machines and arrives in milliseconds. This series demystifies that miracle. We focus on the parts that matter most for developers and interviews — HTTP, TCP/IP, DNS, and REST APIs — taught the simple way, with lots of pictures and analogies.

Every topic is taught the same way: plain-English idea → ASCII picture → real-world analogy → trace it by hand → gotchas table → interview Q&A.

How to Use This Series

1. Go in order — HTTP makes more sense after TCP and DNS.
2. Keep the "type a URL" deep dive as your mental map for how
   every piece connects.
3. Do the Interview Questions out loud.
4. TCP vs UDP, the 3-way handshake, DNS, and HTTP status codes
   are the interview favorites — know them cold.

Keep learning, keep connecting! See you in the chapters!
