Fun Fact
Octal numbering was historically popular in early computing because it aligns perfectly with binary groups of three bits, while hexadecimal later became dominant since it maps cleanly to four-bit binary chunks.
Historical Context
In the early days of computing during the 1950s and 1960s, many systems used 12-bit and 24-bit architectures, making octal notation extremely practical for engineers. As computing shifted toward 8-bit-based architectures, hexadecimal became more prevalent. Today, both number systems remain foundational in computer science education and digital system design.
