Boolean Having two possible values (such as 0 or 1, on or off, true or false).Referring to a system of algebra and logic developed by English mathematician George Boole.
Boolean algebra A system of mathematics developed by George Boole in the 1850s.Boolean algebra uses the operators AND, OR, and NOT; operations are carried out on variables which can have one of two values: 1 (true) and 0 (false).Combinations of AND, OR, and NOT are used to construct the additional functions of XOR, NAND, and NOR.Boolean algebra is very important in computers.
Boolean data Data that can have the value of 1 or 0; these values are also represented as yes or no, on or off, true or false.
Boolean logic Logic derived from Boolean algebra. Boolean logic is the basis of modern digital computing, in which the opening and closing of electronic switches represent the truth values 1 (true) and 0 (false) and the functions AND, OR, and NOT.
Boolean operators AND, OR and NOT. See also Boolean algebra.
Boolean query A query using one or more of the Boolean operators AND, OR, and NOT. For example, a search for all species of snakes which live in North America OR South America, do NOT live in Africa, AND are poisonous. See Boolean algebra.
