Digital logic gates are fundamental building blocks of digital circuits. They perform basic logical functions that are essential for processing binary information. Each gate takes one or more binary inputs and produces a single binary output based on a specific logical operation, such as AND, OR, or NOT. These gates are used in various electronic devices, including computers and smartphones, to perform calculations and control operations. By combining multiple gates, more complex circuits can be created, enabling advanced functionalities in digital systems. Common types of gates include AND, OR, NOT, NAND, and NOR.
