NOR N0150400 (nôr)n. 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 N0150400 (nôr; nər when unstressed)conj. 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.

NOR
NOR[nȯr] (mathematics) A logic operator having the property that if P, Q, R, … are statements, then the NOR of P, Q, R, … is true if all statements are false, false if at least one statement is true. Derived from NOT-OR. Also known as Peirce stroke relationship. NORNot OR.
The Boolean function which is true if none of its inputs aretrue and false otherwise, the logical complement ofinclusive OR. The binary (two-input) NOR function can bedefined (written as an infix operator):
A NOR B = NOT (A OR B) = (NOT A) AND (NOT B)
Its truth table is:
A | B | A NOR B--+---+---------F | F | TF | T | FT | F | FT | T | F
NOR, like NAND, forms a complete set of Boolean functions onits own since it can be used to make NOT, AND, OR and anyother Boolean function:
NOT A = A NOR A
A OR B = NOT (A NOR B)
A AND B = (NOT A) NOR (NOT B)NOR(Not OR) A Boolean logic operation that is true if all inputs are false, and false if any input is true. A NOR gate is constructed of an OR gate followed by a NOT gate.
An exclusive NOR (XNOR) is true if both inputs are the same. An XNOR is constructed of multiple NOR gates. See Boolean logic, flash memory and NAND flash.
