About logical function  :

• A logical operator is indeed a symbol or word that joins two or even more expressions so that the value of the resulting compound expression is exclusively determined by the value of the underlying expressions and the meaning of the operator.

• Common logical operators are AND, OR, and NOT.

• These three logical operators are and, or, and not. The semantics of these operators are comparable to those of their English counterparts.
