Fun Fact
Octal notation was historically popular because early computers used word sizes divisible by three bits, making octal a compact human-readable representation of raw binary data.
Historical Context
Octal encoding became widespread in early computing systems during the 1950s and 1960s when hardware architectures commonly used 12, 24, or 36-bit words. Engineers preferred octal because each digit corresponded exactly to three binary bits, simplifying manual debugging. As Unicode and UTF-8 emerged in the late 20th century, octal remained relevant in programming languages such as C, where escape sequences still rely on octal representations for byte-level precision.
