Logical operators such as AND, OR, and NOT are used to process Boolean values (True or False). A truth table lists all possible input combinations and shows the resulting output of a logical expression. For up to three inputs, you list every possible combination (for example: A, B, and C), then apply each operator according to the logical expression. The AND operator outputs True only if all inputs are True. The OR operator outputs True if at least one input is True. The NOT operator inverts a single Boolean value, making True into False and vice versa.
