Boolean algebra

Definition

Study of mathematical operations performed on certain variables (called binary variables) that can have only two values: true (represented by 1) or false (represented by 0). It provides a set of rules (called Boolean logic) that are indispensable in digital computer-circuit and switching-circuit design. Boolean operation are carried out with algebraic operators (called Boolean operators), the most basic of which are NOT, AND, and OR. Named after its inventor, the UK mathematician and computer pioneer George Boole (1815-65). See also Boolean search.
