Boolean expression is an expression that produces a Boolean value when evaluated, i.e., it produces either a true value or a false value. Whereas Boolean variables are variables that store Boolean numbers.
In computing, the term Boolean means a result that can only have one of two possible values: true or false. Boolean logic takes two statements or expressions and applies a logical operator to generate a Boolean value that can be either true or false. To return the result, operators like AND, OR, NOT, etc. are used.
In mathematics and mathematical logic, Boolean algebra is a branch of algebra. It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted by 1 and 0, whereas in elementary algebra the values of the variables are numbers.
In computer science, a boolean or bool is a data type with two possible values: true or false. It is named after the English mathematician and logician George Boole, whose algebraic and logical systems are used in all modern digital computers. Boolean is pronounced BOOL-ee-an.
In simple words, Boolean logic refers to a form of algebra where the values of the variables are the truth values (also called Boolean values): "true" and "false," often denoted as 1 and 0 respectively.
The meaning of BOOLEAN is of, relating to, or being a logical combinatorial system (such as Boolean algebra) that represents symbolically relationships (such as those implied by the logical operators AND, OR, and NOT) between entities (such as sets, propositions, or on-off computer circuit elements).
Boolean logic is a type of algebra in which results are calculated as either TRUE or FALSE (known as truth values or truth variables). Instead of using arithmetic operators like addition, subtraction, and multiplication, Boolean logic utilizes three basic logical operators: AND, OR, and NOT.
