Binary

Definition

Binary is a numerical system that uses only two digits: 0 and 1. It is not an SI unit but serves as the foundational system for digital computing and electronics. In binary, each digit represents a power of 2.

History

The concept of binary dates back to ancient civilizations, but it was formally defined in the 17th century by Gottfried Wilhelm Leibniz. In the 20th century, its practical application surged with the development of computers, particularly in the 1940s and 1950s.

Uses

Binary is predominantly used in computer science, digital electronics, and data representation. It underpins programming languages, data storage, and network communications. Everyday devices like smartphones and calculators operate using binary.
