Logic Operation Definition/Meaning:
An operation on logical values, producing a Boolean result (see
also Boolean algebra). The operations may be unary or
binary, and are denoted
by symbols known as operators. In general there are 16 logic operations over one
or two operands; they include AND, OR, NOT, NAND, NOR, exclusive-OR, and
Logic operations involving more than two operands can always be expressed in
terms of operations involving one or two operands. Those involving two operands
can be expressed in terms of other operations involving one or two operands.
Logic circuits are fabricated for the implementation of logic operations on
their input signals. The inputs may be words (or bytes), and the logic operation
is applied to each bit in accordance with Boolean algebra.
