**Binary Number System (Base 2):**

**Digits Used**: 0, 1**Explanation**: The binary system is the foundation of digital computing. In this system, every number is represented using only two digits: 0 and 1. Each binary digit is called a bit, and combinations of bits represent different numbers (e.g., the binary number 1011 represents the decimal number 11).**Use Case**: Used in computer systems, logic circuits, and digital communication.

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

- Uses two digits, 0 and 1
- Also called as base 2 number system
- Each position in a binary number represents a 0 power of the base (2). Example 20
- Last position in a binary number represents a x power of the base (2). Example 2x where x represents the last position – 1.
