Ghost - Ghost is a disk cloning program, originally produced by Binary Research, but purchased by Symantec in 1998. The Ghost program created the market for disk-cloning software. The name Ghost originated as an acronym for "General Hardware-Oriented Software Transfer". Symantec official site
Ghosting - Ghosting is a condition where the image prints properly, but a much lighter copy of the image also prints elsewhere. This can be due to a problem with the power outlet that is supplying power to the printer. Check the power outlet by plugging in a different printer to see if the same results occur. Ghosting can also be caused when consumable printer parts, such as the drum or imaging kit, are near the end of their life. All of the consumable parts in a printer are rated for a certain number of pages. Once a printer gets near that number, you'll need to replace those parts to eliminate ghosting.

GIF (Graphics Interchange Format) - A GIF is a palette based image format used for web site graphics and images. It can have a maximum of 256 colors, or 8 bits, chosen from a total of 16.7 Million, or 24 bits. GIFs can also be animated (GIF89a format only) and support transparency. The GIF89a standard also supports interlacing.
GIMP (GNU Image Manipulation Program) - GIMP is an open source application similar to Photoshop for creating and manipulating graphic images. Originally designed for Linux and UNIX-based operating systems, GIMP now runs on Windows and Mac operating systems as well. It is distributed under licensing terms defined by the GNU project. GIMP is typically one of the optional applications that come in any large Linux package such as those distributed by Debian and Red Hat. You can also download it directly from the GIMP web site.
GNOME (GNU Network Object Model Environment) - GNOME (pronounced guh-nome) is part of the GNU project and part of the or open source movement. The GNOME project provides two things: The GNOME desktop environment, an intuitive and attractive desktop for users, and the GNOME development platform, an extensive framework for building applications that integrate into the rest of the desktop. GNOME is the official desktop of the GNU project and is available for most Linux and Unix operating systems. GNOME official site
GNU (GNU's Not Unix) - The GNU (pronounced guh-new) Project was launched in 1984 to develop a complete UNIX-like operating system which is free software: the GNU system. Variants of the GNU operating system, which use the kernel called Linux, are now widely used; though these systems are often referred to as “Linux”, they are more accurately called GNU/Linux systems. GNU was created by the Free Software Foundation and distributes it's software under the GNU Public License (GPL). GNU official site
GPL (Gnu Not Unix Public License) - GPL is a licensing method commonly used in the Linux world. When a programmer decides to place his work under the GPL, they have an obligation to freely give this software, without charges and to publish all of the source code. Only shipping, handling and media can be billed. Whenever the author makes updates to the software, it must be publicly published along with the updated code. GNU Official site
GPS (Global Positioning System) - GPS refers to satellite-based radio positioning systems that provides one's exact location anywhere on or near the surface of the Earth. The NAVSTAR system, operated by the US Department of Defense, was the first GPS system widely available to civilian users who now use it for navigation purposes. Many corporations, such as UPS, use this technology for inventory tracking. GPS is made possible by a series of at least 24 geosynchronous satellites.
Group Policy - Group Policy and the Active Directory services infrastructure in Windows Server 2000 and 2003 enable IT administrators to automate one-to-many management of users and computers. By editing Group Policy Objects (GPOs) which contain policy settings and targeting the GPO at the intended machines or users, specific configuration parameters can be managed centrally. In this way, potentially thousands of machines or users can be updated via a simple change to a single GPO.
GUI (Graphical User Interface) - A GUI (pronounced goo-ee) is a software front-end on a computer meant to provide an attractive and easy to use interface between a computer user and application. This is accomplished via the use of an external pointing device, such as a mouse, and a graphical interface consisting of icons, folders, menus, etc., as opposed to a command-line interface. The first GUI was created by Xerox in the late 70's and later became part of Mac and Windows operating systems.
