🗺️ The Complete Learning Roadmap: From Electricity to Cybersecurity

A step-by-step roadmap that builds your knowledge from the fundamentals of electricity to advanced cybersecurity, ensuring you understand how every layer of technology connects.

👋 Introduction

One of the biggest mistakes beginners make is jumping directly into advanced topics like ethical hacking, penetration testing, malware analysis, or reverse engineering without first understanding the technologies that make them possible.

Questions like:

⚡ What is electricity?
🔧 How does a computer actually work?
💾 What happens when you save a file?
🌐 How does data travel across a network?
🌍 How does a website work?
🔒 How do operating systems protect data?

All of these are connected.

Modern technology is built in layers. Every layer depends on the one below it. If you skip the fundamentals, advanced concepts become much harder to understand.

This roadmap is designed to help you learn from the ground up, giving you a strong foundation before moving into specialized fields like software development, embedded systems, networking, or cybersecurity.
