Which gates are called universal gates? What are its advantages?
Answer
NAND and NOR are universal gates, capable of constructing any Boolean logic function without requiring other gate types.
In digital engineering, the NAND gate and the NOR gate are explicitly classified as "Universal Gates". This powerful designation means that any arbitrary Boolean algebraic function, and any other basic logic gate (AND, OR, NOT, XOR), can be physically constructed utilizing entirely interconnected networks of just NAND gates or just NOR gates, drastically reducing manufacturing supply chain complexity.
