Fun Fact
Unix file permissions are often displayed in octal notation because each octal digit maps cleanly to three binary bits.
Historical Context
Octal numbers were widely used in early computing systems because they provided a compact, human-readable representation of binary data. Before hexadecimal became dominant, octal was the preferred base for many minicomputers and operating systems.
