Boolean expression
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.

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 […]
