binary digit

A **binary digit**, or **bit**, is either $0$ or $1$.

The set of binary digits is the **boolean domain** $\mathbb{B}$.

As a unit of information, a **bit** is the amount of information needed to specify which of the $2$ possibilities a given binary digit is. In natural units, a bit is $ln 2$.
