Definition

Octal refers to a number system that uses a base of 8. Unlike the decimal system we use every day (base 10), octal only uses the digits 0 through 7. It's often used in computer programming as a shorthand for binary code. Think of it as a compact way to represent data. Programmers sometimes use octal to simplify long strings of binary.

Etymology

The word "octal" comes from the Latin word "octo," which means "eight." It signifies the use of eight as the base of the number system.
