DDR SDRAM – Double Data Rate
SDRAM is a further development of
➟
SDRAM memory technology. While
SDRAMs only provide data at the actual
system clock speed, DDR chips permit
data to be accessed at twice the system
clock speed.
쎲
DRAM – Abbreviation for Dynamic Ran-
dom Access Memory. Dynamic random
access memory with direct access.
쎲
EDO-RAM – Abbreviation for Extended
Data Output Random Access Memory
(hyper page mode). EDO-RAM is especial-
ly advantageous in graphics boards be-
cause the most recently required data re-
mains held in memory. Image rendering in-
volves multiple consecutive read access of
similar data, so EDO-RAM results in signif-
icantly faster speeds.

FBAS –
➟
Composite video
쎲
FCC – The FCC radiation standard states
that this device has been tested and meets
the requirements for digital class B de-
vices in accordance with section 15 of the
guidelines as provided by the American
Federal Communications Commission
(FCC).
쎲
Fixed-frequency monitor – A monitor
that can only be operated with at a specif-
ic resolution and refresh rate.
쎲
FIFO method – Abbreviation for first in,
first out: A system used in batch process-
ing and queues, in which the first arriving
signal is processed first.

쎲
Frame buffer – Memory on the graphics
board containing display information, es-
pecially the
➟
Front buffer and
➟
Back
buffer
쎲
Front buffer – Refers to the visible im-
age area in the case of
➟
Double buffer .
쎲
Full-scene anti-aliasing – Describes a
type of
➟
Anti-aliasing that is applied to
a complete frame. Two processes are used
in this form of anti-aliasing: Super
sampling and Accumulated buffers. In the
case of super sampling, a much higher res-
olution is calculated than the one to be
displayed and then reduced. With the ac-
cumulated-buffer process, several views
of a scene are drawn that are then com-
bined to a single image.
쎲
Geometrical transformation – The po-
sition of the objects in space is determined
based on the observer.

Graphics accelerator –
ELSA GLADIAC 511 is a graphics accelera-
tor card that is especially well-suited for
the user environment that requires intense
graphics.
쎲
HighColor – Stands for a graphic display
mode with 15 or 16 bit color depth per pix-
el (32,768 or 65,536 colors).
쎲
Horizontal frequency – The monitor li-
ne frequency (horizontal scan frequency) in
kHz. This value must be set according to
the monitor's requirements to prevent the
monitor from being damaged in extreme
cases!
