**Octal Number System (Base 8):**

**Digits Used**: 0, 1, 2, 3, 4, 5, 6, 7**Explanation**: The octal system is less common but was historically used in computing. Each octal digit represents three binary digits, making conversions between binary and octal straightforward (e.g., the octal number 17 represents the binary number 001 111).**Use Case**: Used in some computing applications, particularly older systems.

**Characteristics of the octal number system are as follows −**

- Uses eight digits, 0,1,2,3,4,5,6,7
- Also called as base 8 number system
- Each position in an octal number represents a 0 power of the base (8). Example 80 Last position in an octal number represents a x power of the base (8). Example 8x where x represents the last position – 1
