Fun Fact
Hexadecimal became popular in computing because one byte maps perfectly to two hex digits, making it far easier for engineers to read and debug binary data visually.
Historical Context
Hexadecimal notation emerged alongside early digital computers in the 1950s as engineers sought a compact representation of binary memory addresses. It became a universal debugging standard during the rise of assembly programming and remains fundamental in modern computing, networking protocols, and cryptographic systems.
