A logical operator that consists of a logical OR followed by a logical NOT and returns a true value only if both operands are false.

nor 1

 (nôr; nər when unstressed)
And not; or not; not either: has neither phoned nor written us; life forms that are neither plants nor animals.

[Middle English : ne, no; see no1 + or, or; see or1.]
Usage Note: When neither begins a balanced construction that negates two parts of a sentence, nor, not or, must introduce the second part. Thus standard usage requires He is neither able nor (not or) willing to go. Similarly, nor (not or) must be used to start the second of two negative independent clauses: He cannot find anyone now, nor does he expect to find anyone in the future. Jane will never compromise with Bill, nor will Bill compromise with Jane. Note that in these constructions nor causes an inversion of the auxiliary verb and the subject (does he... will Bill). However, when a verb is negated by not or never, and is followed by a negative verb phrase (but not an entire clause), either or or nor is acceptable: He will not permit the change or (or nor) even consider it. · In noun phrases of the type no this or that, or is more common than nor: He has no experience or interest (less frequently nor interest) in chemistry. Or is also more common than nor when such a noun phrase, adjective phrase, or adverb phrase is introduced by not: He is not a philosopher or a statesman. They were not rich or happy. The senator did not speak persuasively or movingly on the issue. See Usage Notes at neither, or1.

2. (used to continue the force of a negative, as not, no, never, etc., occurring in a preceding clause): I never saw him again, nor did I regret it.
3. (used after an affirmative clause, or as a continuative, in the sense of and not): They are happy, nor need we worry.
4. Older Use. than.
5. Archaic. (used without a preceding neither, the negative force of which is understood): He nor I was there.
6. Archaic. (used instead of neither as correlative to a following nor): Nor he nor I was there.
[1300–50; Middle English, contraction of nother, Old English nōther=ne not + ōther (contraction of ōhwæther) either; compare or1]
usage: See neither.

1. 'neither ... nor'

You can use nor with neither to make a negative statement about two people or things.

Neither Maria nor Juan was there.
He spoke neither English nor French.
2. used for linking clauses

Nor is also used for linking negative clauses. You put nor at the beginning of the second clause, followed by an auxiliary verb, a modal, or be, followed by the subject and the main verb, if there is one.

The officer didn't believe me, nor did the girls when I told them.
We cannot give personal replies, nor can we guarantee to answer letters.
3. 'nor' in replies

You can reply to a negative statement using nor. You do this to show that what has just been said also applies to another person or thing. You can use neither in the same way with the same meaning.

'I don't like him.' – 'Nor do I.'
'I can't stand much more of this.' – 'Neither can I.'

An AND gate inverts the signal propagated by a NAND gate while an OR gate inverts that propagated by a NOR gate. Note that, in CMOS technology, an and-gate is a NAND gate coupled with a NOT gate and an OR gate is a nor-gate followed by a not-gate and not the inverse [4].
