dots that make the image as the image gets bigger the image is the bigger
the dots will get bigger making the texture/granularity become less
clear.

character - To create
letters and numbers on-screen, the computer creates them as graphics and
stores them as binary codes.
Graphical
kernel system (GKS) -
An international standard for computer graphics that defines how graphics
are handled by software, rather than hardware. The system allows graphics
to be created on one computer system and then viewed on another with few
or no alterations.
Graphic
user interface (GUI) -
Uses graphical symbols (called icons) and menus to carry out commands
such as opening files delete files, move files... Most GUI's use a mouse
however can still operate with a keyboard which allows the inexperienced
users to use the computer easier then having to learn all the commands
with a non GUI such as DOS, Unix, and Lynix.
Graphics
accelerator card -
Circuit board that reduced time that the computer takes to produce images
on the computer screen. It allows the computer to work faster because it
has its own memory and processor built in to handle basic graphic
functions.

- The common point in
electrical/electronic circuits. All electrons flow toward the path of
least potential difference just as water always flows downhill. In
electronic terms, Ground is the point that measurements regarding the
potential and started. Grounding is very important for safety reasons. A
properly grounded system will cause errant current to flow into the
ground thereby not damaging people or equipment.
Ground
Loops - Magnetic field
usually generated in STP cabling which is the ground voltage of each end
of cable run is different causing a flow in the cable's shield,
generating noise because of the Magnetic field.
Grounding
- Act of touching a un-painted surface of metal to help set the person
touching the metal at 0 potential to help prevent the computer from
having more electricity then you and you to not have more electricity
then the computer to help prevent electric static discharge.
Group
3 protocol - An
international standard for facsimile protocols that defines how two
systems will send and receive faces over regular phone lines. Group 3
protocol, as well as groups 1,2,3 bis, and 4 protocols, were devised by
International Telecommunications Union Telecommunications (ITU-T) in
machines for different manufacturers could communicate with each other.
Group
4 protocol -
International standard for facsimile protocols that defines how two
systems send and receive faxes over Integrated Services Digital Network
(ISDN) lines.
Group
Icon - Refer to
program group.
