(A) Logic gate
(B) Automatic gate
(C) Program gate
(D) None of these
🧠 Explanation:
AND, OR, XOR, NOT, NAND, and NOR are types of **logic gates** used in digital electronics. These gates perform basic logical functions on one or more binary inputs to produce a single binary output. They are fundamental building blocks of digital circuits and are used to create complex computational and decision-making systems within computers and other electronic devices. Each gate follows specific rules to manipulate input signals and determine the output based on Boolean algebra principles.
