Number Systems

Step 1: Define the base of a number system. The base (or radix) of a number system is the number of unique digits or symbols used to represent numbers in that system.
Step 2: Define the octal system. The octal number system is base-8. It uses eight digits: 0, 1, 2, 3, 4, 5, 6, and 7. The name "octal" comes from the Latin root "octo", meaning eight.

Base 10 is Decimal.
Base 2 is Binary.
Base 16 is Hexadecimal.

Step 1: Define the binary number system. The binary system is a base-2 number system. This means it only uses two distinct symbols to represent numbers.
Step 2: Identify the symbols. The two symbols used in the binary system are 0 and 1. Each digit in a binary number is called a "bit".
