Alternative Logic Gate II - SS2 ICT Past Questions and Answers - page 3

NAND gates and NOR gates exhibit different output behaviors based on their input combinations. In a NAND gate, the output is 0 only when both inputs are 1; otherwise, the output is 1. In contrast, a NOR gate produces a 0 output only when both inputs are 1; otherwise, the output is 1. These differences in output behavior stem from the logical operations of NOT, AND, and OR that are inherent to NAND and NOR gates, respectively.
