Boolean expressions are fundamental to computing, based on George Boole's 19th-century work. They use binary values and logical operators like AND, OR, and NOT to yield true or false outcomes. Understanding Boolean algebra's laws, such as Commutative, Associative, and De Morgan's, is crucial for simplifying expressions and optimizing algorithms. Boolean logic is also key in database queries, digital electronics, and video game development.
