## Binary Terms

**Binary.** A number system that uses a base, or radix, of 2. Two digits (1 and 0) are used in the binary system. Pertaining to a characteristic that involves the selection, choice, or condition in which there are only two possibilities. A bistable multivibrator (flip-flop) is one example of a binary device.

**Binary Code.** A method of representing two possible conditions (on or off, high or low, one or zero, the presence of a signal or absence of a signal). Electronic circuits designed to work in such a way that only two conditions are possible.

**Binary-Coded.** The state in which conditions are expressed by a series of binary digits (0s and 1s).

**Binary Coded Decimal.** [BCD], A Binary number system that counts from 0 to 9 [decimal]. BCD Conversion Table, also BCD Conversion Circuit.

**Binary Digit.** A character that represents one of the two digits in the number system that has a radix of two. Either of the digits 0 or 1 that may be used to represent the binary conditions of on or off.

**Binary Notation.** See Binary Number System. Any notation that uses two
different characters, usually the digits 0 and 1.

**Binary Number System.** A number system using two digits, symbols, or characters (usually 1 and
0). A number that is expressed in binary notation and is usually characterized by the
arrangement of bits in sequence, with the understanding that successive bits are interpreted as
coefficients of successive powers of the base 2. Symbol Encoding Table

**Binary Point.** The radix point that separates powers of two and fractional powers of two in a binary number.
