It also contains information specified by the D list and information generated for the C list. The whole list may read by the INIT through the READ DEFECTIVE DATA command.

Gamma CorrectionScanners. The correction of tonal ranges in an image, normally by the adjustment of tone curves.
 
GCR (Grey Component Replacement)Scanners. A technique for reducing the amount of cyan, magenta and yellow in an area and replacing them with an appropriate level of black

GeckoGecko is a free web browser layout engine designed to support open Internet standards such as HTML 4.0, CSS 1/2, the W3C Document Object Model, XML 1.0, RDF, and JavaScript. It is written in C++. Gecko is developed by the Mozilla Foundation under the project names NGLayout (the renderer) and XPFE (for cross-platform user interfaces). NGLayout was previously called Raptor and originally meant "Next Generation Layout", but has been adopted by Netscape to be "Netscape Gecko Layout". Gecko offers a rich programming API (http://www.mozilla.org/projects/embedding/) that makes it suitable for a wide variety of roles in Internet enabled applications, such as web browsers, content presentation and client/server. Primarily it is used for the Mozilla browser derivatives such as Netscape and Mozilla Firefox, but it is used elsewhere as well.

GNUA free software movement whose acronym stands recursively for "GNU's Not Unix." GNU was started in 1984 as a means to create an entire system of software, including operating systems, programming languages, and applications that are all free. In this context free means free of cost, free to distribute, free to modify, and free to distribute modified versions. The main thing you are not free to do is claim ownership of GNU software.
 
GogoolThis stands for the number 10 raised to the power of 100 (10^100), or a one followed by 100 zeros.
 
GogoolplexThe number 10 raised to the power of 1 google, or (10^(10^100)), which is the number 1 followed by 10^100 zeros.

Government Secure Intranet (GSI)An intranet that links UK government departments.
 
GPL (GNU Public Licence)The short of it is quite simple: if you based anything on GPLed software, you MUST provide the source code to your software upon request. The legalities of this simple concept go on at great length, and periodically new revisions of the GPL appear as holes are found and fixed. The primary rival to this is the BSD license, which is "free beer" for the community, but developers of FreeBSD license software can choose to keep their source hidden.
 
GreyscaleScanners. 1. An image type consisting of shades of grey, with no colour. The standard greyscale image contains 8 bits per pixel, which allows for 256 shades. 2. The depiction of grey tones between black and white. A greyscale monitor is able to display distinct grey pixels as well as black and white ones, but not colour pixels. 3. An orderly variable progression in definite steps of grey densities ranging from minimum zero (white) to maximum density (black). A strip of standard grey tones placed at the side of the original copy during a photography to measure tonal range obtained. Used in processing film or materials such as photographic paper and plates.
 
Grounded TheoryAn inductive, theory discovery methodology that allows the researcher to develop a theoretical account of the general features of a topic while simultaneously grounding the account in empirical observations or data. Martin and Turner 1986.
