In Boolean logic, logical NOR, [1] non-disjunction, or joint denial [1] is a truth-functional operator which produces a result that is the negation of logical or.That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both p and q are false.
Nor or NOR may refer to: Nor, a word used with "neither" in a correlative conjunction (e.g. "Neither the basketball team nor the football team is doing well.") Nor, a word used as a coordinating conjunction (e.g. "They do not gamble, nor do they smoke.")
definition: is defined as metalanguage:= means "from now on, is defined to be another name for ." This is a statement in the metalanguage, not the object language. The notation may occasionally be seen in physics, meaning the same as :=.
In English, as in many languages, such expressions are typically grammatical conjunctions. However, they can also take the form of complementizers , verb suffixes , and particles . The denotations of natural language connectives is a major topic of research in formal semantics , a field that studies the logical structure of natural languages.
A single NOR gate. A NOR gate or a NOT OR gate is a logic gate which gives a positive output only when both inputs are negative.. Like NAND gates, NOR gates are so-called "universal gates" that can be combined to form any other kind of logic gate.
NOR is the result of the negation of the OR operator. It can also in some senses be seen as the inverse of an AND gate. NOR is a functionally complete operation—NOR gates can be combined to generate any other logical function. It shares this property with the NAND gate.
"Nor" is an abbreviation of normal. Originally, the term was used to denote the completely demethylated form of the parent compound. [4] Later, the meaning was restricted to the removal of one group. Nor is written directly in front of the stem name, without a hyphen between, unless there is another prefix after nor (for example α-).
