Boolean logic was invented by George Boole, who lived from 1815 to 1864. Boole was a mathematician and philosopher who did extensive work in differential equations and symbolic logic. Boolean logic paved the way for electrical switches to process logic, which is a concept that underlies modern computers.
Boolean logic is based on binary numbers, which are zeros and ones. A zero typically represents a false, low or zero volt, and a one represents a true, high or positive voltage. The three most basic operations of Boolean algebra are "and," "or" and "not." Boolean logic helps to determine which operation to use.
