What numbers does a binary system involve?

A binary system exclusively involves the numbers 0 and 1. It is the foundational number system used in digital computing and electronic systems, where each digit represents a power of two. In this system, the digit '0' typically signifies an "off" state, while '1' signifies an "on" state. The simplicity of having just two values allows for efficient data representation, processing, and storage in modern computing technology. Each binary digit, or bit, can combine in various ways to represent more complex data structures, enabling the functioning of everything from simple calculations to intricate algorithms.
