The "Logical AND" is a fundamental operation in logic and computer science that combines two or more conditions. It evaluates to true only when all the conditions are true. For example, if you have two statements, A and B, the result of A AND B will be true only if both A and B are true. In programming, the Logical AND is often represented by the symbol "&&". It is commonly used in conditional statements to control the flow of a program. For instance, if a user must meet two criteria, such as being over 18 years old and having a valid ID, both conditions must be satisfied for the action to proceed.
