noun
NAND operation; non-conjunction
A logical operation in computing; output is false only when all inputs are true. Equivalent to NOT (A AND B).
否定積は論理回路の基本演算の一つです。
The NAND operation is one of the fundamental operations in logic circuits.
この回路は否定積ゲートで構成されている。
This circuit is composed of NAND gates.
否定論理和 (NOR) outputs true only when all inputs are false, whereas 否定積 (NAND) outputs false only when all inputs are true.
Compound of 否定 (negation) and 積 (product, here meaning logical conjunction). The term is a direct translation of the English 'non-conjunction' or 'NOT-AND'.
