Binary Code vs. Gray Code: Key Differences Explained

Binary code is a coding system that uses the binary number system (base-2) to represent data and instructions. Each digit in binary code can have only one of two possible values: 0 or 1. It's the primary coding system used within computers to represent numbers, characters, images, sounds, and various other information.

Gray code, also known as reflected binary code, is a special type of binary code. Its key characteristic is that adjacent values differ in only one binary digit. This means that when transitioning from one number to the next, only a single bit changes, minimizing errors and making it suitable for various applications.

The primary distinction between binary code and Gray code lies in their coding methods. Binary code uses two possible values per digit, while Gray code ensures only one bit changes between successive values. This unique property of Gray code makes it advantageous in situations where error prevention and reliable signal transmission are crucial, such as digital conversion, digital counters, and digital signal transmission.
