Definition
In computer science and mathematics, 'boolean' refers to a type of data or variable that has only two possible values: true or false. Think of it as a simple on/off switch. It's like asking a yes/no question. Boolean logic is fundamental to digital circuits and programming. It forms the basis of conditional statements and decision-making processes in software. 'Boolean' is named after George Boole, a 19th-century mathematician who developed Boolean algebra.
