What are the basic building blocks for digital circuits called?

• A. Digital units
• B. NOT gate
• C. Logic gates
• D. Boolean algebra

Answer: (C)

Logic gates are the basic building blocks for digital circuits. They operate on binary inputs and produce binary outputs according to fixed truth tables. By combining gates like AND, OR, and NOT, you can realize any boolean function, and even build complex circuits from a single universal type such as NAND or NOR. The other terms don’t refer to the hardware components themselves: a NOT gate is only one gate, not the entire set of building blocks; Boolean algebra is the mathematical framework used to reason about logic, not the physical components.
