NAND operation; non-conjunction
A logical operation in computing; output is false only when all inputs are true. Equivalent to NOT (A AND B).
The NAND operation is one of the fundamental operations in logic circuits.
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'.
