# A logic circuit is a fundamental building block of digital systems that processes binary information using interconnected logic gates. These gates (such as AND, OR, NOT, NAND, etc.) are electronic components whose behavior is governed by Boolean algebra, the mathematical framework for manipulating variables that have only two possible states (0 and 1). | # A logic circuit is a fundamental building block of digital systems that processes binary information using interconnected logic gates.
