Boolean describes a type of logic or data that has only two possible values, usually true or false, yes or no, 1 or 0.
It is named after George Boole, a 19th-century English mathematician who developed a system of logic based on true/false values. His ideas became the foundation of modern digital computing.
Every time a computer makes a decision, it’s secretly doing Boolean logic—millions of tiny true/false questions every second. The entire digital world rests on this simple idea that everything can be reduced to two choices.
