anti-aliasing
<graphics> A technique used on a grey-scale or colour bitmap display to
make diagonal edges appear smoother by setting pixels near the edge to
intermediate colours according to where the edge crosses them.
The most common example is black characters on a white background. Without
anti-aliasing, diagonal edges appear jagged, like staircases, which may be
noticeable on a low resolution display. If the display can show intermediate
greys then anti-aliasing can be applied. A pixel will be black if it is
completely within the black area, or white if it is completely outside the black
area, or an intermediate shade of grey according to the proportions of it which
overlap the black and white areas. The technique works similarly with other
foreground and background colours.
"Aliasing" refers to the fact that many points (which would differ in the real
image) are mapped or "aliased" to the same pixel (with a single value) in the
digital representation.

antichain
<mathematics> A subset S of a partially ordered set P is an antichain if,
for all x, y in S, x <= y => x = y
I.e. no two different elements are related.

antisymmetric
<mathematics> A relation R is antisymmetric if,
for all x and y, x R y and y R x => x == y.
I.e. no two different elements are mutually related.
Partial orders and total orders are antisymmetric. If R is also symmetric, i.e.
x R y => y R x
then
x R y => x == y
I.e. different elements are not related.

antivirus software
<tool> Programs to detect and remove computer viruses. The simplest kind
scans executable files and boot blocks for a list of known viruses. Others are
constantly active, attempting to detect the actions of general classes of
viruses. antivirus software should always include a regular update service
allowing it to keep up with the latest viruses as they are released.
