Introduction to the Octal System
Explore the octal system as a compact way to represent binary numbers using base-8 notation. Understand how octal groups binary digits in triplets, learn its symbols and place values, and practice converting between binary and octal numbers.

A less widely used number system is the octal system. It was developed under the same idea as the hexadecimal system, to more compactly represent binary numbers.
The octal system is different from the hexadecimal system in that it groups binary numbers into triplets to represent them, instead of quartets. For example, we can divide the number like: ...
