Fun Fact
Every hexadecimal digit represents exactly four binary bits. That is why hex is widely used in computing - it provides a compact and human-readable representation of binary data without losing precision.
Historical Context
Hexadecimal notation became popular with the rise of early digital computers in the mid-20th century. Engineers needed a concise way to represent binary machine code and memory addresses. Base-16 provided a practical bridge between human readability and binary architecture. Today, hexadecimal remains foundational in computing, networking, cryptography, and digital systems worldwide.
