Day 1 — Journey to Becoming a Complete Full-Stack Developer (2026 Edition) 🚀

Starting from absolute beginner → professional engineer in 1 year.

Phase 0: Foundation

Before writing a single line of code, I’m focusing on understanding how computers, the internet, and developer tools actually work.

Today’s focus: How the Internet Works 🌐

Here’s what I’ve covered:

What happens when you type a URL into a browser
Breaking down a URL structure:
Protocol (scheme), subdomain, domain, port, path, query string, fragment
Understanding DNS (Domain Name System)
- How human-readable domains translate into IP addresses
- The DNS lookup process:
  Browser cache → OS cache → Recursive resolver → Root name server → TLD name server → Authoritative name server
- How IP addresses are returned, cached, and used to establish a connection

What’s Next (Day 2)

I’m documenting everything as I learn. If you want to follow or check out my roadmap:

Consistency over intensity. See you on Day 2. 💪
