Question

What is the meaning of the operator NOT in boolean logic?

a) Performs a comparison between two values
b) Returns true if both conditions are true
c) Inverts the value of the operand
d) Returns true if either condition is true

Answer 1

The NOT operator in Boolean logic inverts the value of its operand, turning true to false and false to true.

Step-by-step explanation:

The operator NOT in Boolean logic is used to invert the value of the operand. If the original Boolean value is true, the NOT operator will change it to false, and vice versa. This is different from the AND operator, which returns true only if both conditions are true, and the OR operator, which returns true if either condition is true. For example, the NOT operator can be used to exclude certain terms in a database search, refining your search results.
