🔢 Hexadecimal Numbers Explained for Beginners!

In this video, I dive into the basics of Hexadecimal (Hex) Numbers and explain their importance, especially in networking!

📚 What you'll learn:
✅ Binary (Base-2) uses digits 0 and 1
✅ Decimal (Base-10) uses digits 0 to 9
✅ Hexadecimal (Base-16) uses digits 0–9 and letters A–F

📈 I cover:
🔹 Mapping decimal numbers 0 to 15 to their Hex equivalents
🔹 Understanding how:
 • 0–9 map directly
 • 10–15 map to A–F

🔹 Why 4 binary bits are needed to represent a single Hex digit:
 • 1 bit = 2 combinations
 • 2 bits = 4 combinations
 • 3 bits = 8 combinations
 • 4 bits = 16 combinations (perfect for Hex!)

🌐 Real-world applications:
• MAC Addresses
• IPv6 Addresses

🎯 A must-watch if you're beginning your networking journey or just curious about Hexadecimal!
