NAND Operation Definition/Meaning:
The logical connective combining two statements, truth values, or formulas P
and Q in such a way that the outcome is true only if either P or Q or both is
false. The NAND operation may be represented by the Sheffer stroke,
|, or by ∆. P|Q is just the negation of P A Q, hence the name
(see AND operation).
The NAND operation is of particular significance to computer designers since any
Boolean expression can be realized by an expression using only the NAND
operation. In practical terms, circuits can be built using only NAND gates.
