Nor \Nor\ (n[^o]r), conj. [OE. nor, contr. from nother. See
{Neither}.]
A negative connective or particle, introducing the second
member or clause of a negative proposition, following
neither, or not, in the first member or clause (as or in
affirmative propositions follows either). Nor is also used
sometimes in the first member for neither, and sometimes the
neither is omitted and implied by the use of nor.

NOR
Not OR.
The {Boolean} function which is true if none of its inputs are
true and false otherwise, the {logical complement} of
{inclusive OR}. The binary (two-input) NOR function can be
defined (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 | T
F | T | F
T | F | F
T | T | F
NOR, like {NAND}, forms a complete set of {Boolean} functions on
its own since it can be used to make NOT, AND, OR and any
other Boolean function:
NOT A = A NOR A
A OR B = NOT (A NOR B)
A AND B = (NOT A) NOR (NOT B)
