Binary state
VocabularyA representation uses two distinguishable possibilities for each position.
Explanation or usage
A binary position can represent alternatives such as raised or unraised, rather than only written digits. Assigning 0 and 1 is a convention that makes the distinction easy to manipulate. A collection of binary positions can encode many meanings through combinations.
Common misunderstandings
Binary representation requires visible numerals.

Six-position Braille cells illustrate binary patterns: each dot position is raised or unraised. This is an analogy about two-state representation; Braille is not a programming language.
