absolute address
: is the
actual
address
to which a
variable
is
mapped
, which is the
memory location
that
hold
s the
variable
’s
value
.
abstract class
: is a
class definition
that is not fully
implement
ed; one or more
class method
s remain
undefined
with the
result
that no
object
s can be
instantiate
d from the
class
.
abstract
data type
(
ADT
): is a
conceptual
model
of
form
and
function
; a
data [[definition
is
separate
d into an
interface
and an
implement
ation
where
the
implementation
detail
s are
hidden
so that an
ADT
is
characterize
d by its
utility
, which is the
functionality
provide
d via its
interface
. For
example
, a
stack
is an
ADT
that
provide
s a
LIFO
(last-in,
first
-
out
)
order
ing of
data
;
implementation
detail
s of the
stack
container
are not
relevant
to its
use
.
agile software development
aliasing
Boolean logic
:
govern
s the
representation
of
true
and
false
value
s as well as the
rule
s that
determine
the
truth value
of a given
equation
. For
example
, the
truth value
of a
conjunction
(
AND
) of two
Boolean
value
s is
true
if and only if both
value
s are
true
; the
truth value
of a
disjunction
(
OR
) of two
Boolean
value
s is
false
if and only if both
value
s are
false
.
