👉 Octal is a numeral system used in computing and telecommunications. It uses 8 digits (0, 1, 2, 3, 4, 5, 6, 7) to represent numbers, which are binary systems with two's complement for positive numbers. The octal number system has the advantage of having fewer digits than the decimal system but it also requires more memory space to store all the digits since each digit is represented by a bit.
