Binary notation is a representation of data and information in two forms, usually ones and zeroes. Synonyms for binary notation include digital notation, dual notation, base-2 notation, and Boolean notation. Digital notation refers to the representation of data in the form of discrete values, which can be encoded in binary form. Dual notation and base-2 notation both refer to the fact that binary notation is a system that uses two digits. Boolean notation usually refers to the logical operations used in binary notation, such as AND, OR, and NOT. Regardless of the synonym used for binary notation, it remains a crucial representation of information in modern computing.
