Boolean operators are fundamental concepts in logic and computer science, used to combine or modify true/false values, known as Boolean values. The most common Boolean operators are AND, OR, and NOT.

The AND operator returns true only if both operands are true. For example, "true AND true" evaluates to true, but "true AND false" evaluates to false. This operator is useful for specifying conditions where all criteria must be met.

The OR operator returns true if at least one of the operands is true. For instance, "true OR false" evaluates to true, and "false OR false" evaluates to false. The OR operator is employed when any one of several conditions is sufficient.

The NOT operator is a unary operator that reverses the Boolean value of its operand. If an operand is true, "NOT true" evaluates to false, and if an operand is false, "NOT false" evaluates to true. This operator is used to negate a condition.

These operators form the basis for conditional statements, database queries, search engine operations, and circuit design. Understanding Boolean operators is essential for anyone working with logic or programming.
