In electronics circuits, digital logic or boolean logic represents signals and sequences in a digital circuit. These rules allow us to make complicated decisions based on simple binary (yes/no) questions, ultimately forming the basis for how circuits and hardware communicate.Logic components perform different functions on inputs. These include gates, multiplexers, encoders, decoders, flip-flops, and comparators. The most common type of logic component is a logic gate,which also comes in several variations: AND, OR, NOT, NAND, NOR, XOR, and XNOR.
