Fun Fact
Octal notation was widely used in early computing systems because it provided a compact representation of binary values, reducing manual errors when working with long binary sequences.
Historical Context
During the early era of computing in the mid-20th century, octal became a preferred shorthand for binary because many machines used word sizes divisible by three bits. Engineers used octal extensively for memory addressing, machine instructions, and debugging long before hexadecimal became the dominant notation.
