NOR gate; NOR element
Technical term in digital logic; a logic gate that outputs true only when all inputs are false.
A NOR gate outputs true only when all inputs are false.
OR gate; outputs true when at least one input is true, whereas 否定論理和素子 outputs true only when all inputs are false.
NAND gate; outputs false only when all inputs are true, while 否定論理和素子 outputs true only when all inputs are false.
Compound of 否定 (negation), 論理和 (logical sum, OR), and 素子 (element, device). The term directly describes a device that negates the logical OR operation.
