🏁 Conclusion

• Bit → Crumb (2) → Nibble (4) → Byte (8) are the fundamental groupings of binary data.
• Upper/Lower nibble make byte parsing and hex representation straightforward.
• LSB/MSB determine each bit’s weight and are key in numeric value and flag interpretation.
  
  

Mastering these byte parts turns “scary binary” into a clean, predictable structure you can read and write with confidence. 💪
