The NAND is one of the binary operations most heavily used in digital logic, an operation involving two input states, resulting in one of two possible output states. These electronic circuits are known as gates because they control the flow of bits (information) through the overall circuit.
Note that the truth table is independent of fabrication details; i.e. whether it is a CMOS gate or from a different logic "family" does not change the logic of the operation -- the actual gate is constructed to create the desired truth table.
