The binary numeration system is commonly used in computer science and digital technology to represent data. This system only uses two symbols, 0 and 1, to represent all numbers. However, there are several other words that can be used as synonyms for the binary numeration system, such as the base-2 system, dual system, and dyadic system. The base-2 system refers to the fact that the system only has two digits, while the dual and dyadic systems refer to the two-fold nature of the system. Regardless of the term used, the binary numeration system is a foundational concept in digital technologies and plays a crucial role in modern computing.
