An expression that results in a value of either TRUE or FALSE. For example, the expression
2 < 5 (2 is less than 5) is a Boolean expression because the result is TRUE. All expressions that contain relational operators , such as the less than sign (<), are Boolean. The operators -- AND, OR, XOR, NOR, and NOT -- are Boolean operators. Boolean expressions are also called comparison expressions, conditional expressions, and relational expressions.
- Boolean Logic
(bool´ē-&n loj´ik) (n.) Named after the nineteenth-century mathematician George Boole, Boolean logic is a form of algebra in which all values are reduced to either TRUE or FALSE. Boolean logic is especially important for computer science because it fits nicely with the binary numbering system, in which each bit has a value of either 1 […]
- Boolean Operator
There are five Boolean operators that can be used to manipulate TRUE/FALSE values. These operators have the following meanings, where x and y represent values of TRUE or FALSE. The OR operator is often called an inclusive OR, whereas XOR is an exclusive OR. Boolean operators are used widely in programming and also in forming […]
- Boolean Search
A type of search allowing users to combine keywords with operators such as AND, NOT and OR to further produce more relevant results. For example, a Boolean search could be “hotel” AND “New York”. This would limit the search results to only those documents containing the two keywords.
- Boot Configuration Data
Abbreviated as BCD, Boot Configuration Data is used in Windows Vista in place of the boot.ini system file that is found in earlier versions of the Windows operating system.
