Terminology means Technical Definition, here are some terminologies used for computers, they are categorized alphabetically, either you scroll down the page until you reach the terminology you wants, or it would be easier to click the terminology you want from the list. I hope you like this page and make a good use of it, also there will be an updates in the future, you may visit it regularly. | |
Letter G : | Gateway - GIF - Gigabyte - GUI |
Gateway | |
A gateway
is a network point that acts as an entrance to another network. On the Internet, in terms
of routing, the network consists of gateway nodes and host nodes. The computers of network
users and the computers that serve content (such as Web pages) are host nodes. The
computers that control traffic within your company's network or at your local Internet
service provider (ISP) are gateway nodes. In the network for an enterprise, a computer server acting as a gateway node is often also acting as a proxy server and a firewall server. Gateways also involve the use of routers and switches.

GIF (Graphics Interchange Format) | ![]() |
A GIF (some
people say "DJIF" and others say "GIF" with a hard G) is one of the
two most common file formats for graphic images on the World Wide Web. The other is the
JPEG. On the Web and elsewhere on the Internet (for example, bulletin board services), the GIF has become a de facto standard form of image. The format is actually owned by Compuserve and companies that make products that exploit the format (but not ordinary Web users or businesses that include GIFs in their pages) need to license its use. Technically, a GIF uses the 2D raster data type, is encoded in binary, and uses LZW compression. There are two versions of the format, 87a and 89a. Version 89a (July, 1989) allows for the possibility of an animated GIF, which is a short sequence of images within a single GIF file. A GIF89a can also be specified for interlaced presentation. A patent-free replacement for the GIF, the PNG format, has been developed by an Internet committee and major browsers will soon be supporting it.

GigaByte | ![]() |
A gigabyte
(pronounced GIG-a-bite with hard G's) is a measure of
computer data storage capacity and is "roughly" a billion bytes. A gigabyte is
two to the 30th power, or 1,073,741,824 in decimal notation.

GUI | ![]() |
A GUI
(usually pronounced GOO-ee) is a graphical (rather
than purely textual) user interface to a computer. As you read this, you are looking at
the GUI or graphical user interface of your particular Web browser. The term came into
existence because the first interactive user interfaces to computers were not graphical;
they were text-and-keyboard oriented and usually consisted of commands you had to remember
and computer responses that were infamously brief. The command interface of the DOS
operating system (which you can still get to from your Windows operating system) is an
example of the typical user-computer interface before GUIs arrived. An intermediate step
in user interfaces between the command line interface and the GUI was the non-graphical menu-based
interface, which let you interact by using a mouse rather than by having to type in
keyboard commands. Today's major operating systems provide a graphical user interface. Applications typically use the elements of the GUI that come with the operating system and add their own graphical user interface elements and ideas. A GUI sometimes uses one or more metaphors for objects familiar in real life, such as the desktop, the view through a window, or the physical layout in a building. Elements of a GUI include such things as: windows, pull-down menus, buttons, scroll bars, iconic images, wizards, the mouse, and no doubt many things that haven't been invented yet. With the increasing use of multimedia as part of the GUI, sound, voice, motion video, and virtual reality interfaces seem likely to become part of the GUI for many applications. A system's graphical user interface along with its input devices is sometimes referred to as its "look-and-feel." The GUI familiar to most of us today in either the Mac or the Windows operating systems and their applications originated at the Xerox Palo Alto Research Laboratory in the late 1970s. Apple used it in their first Macintosh computers. Later, Microsoft used many of the same ideas in their first version of the Windows operating system for IBM-compatible PCs. When creating an application, many object-oriented tools exist that facilitate writing a graphical user interface. Each GUI element is defined as a class from which you can create object instances for your application. You can code or modify prepackaged methods that an object will use to respond to user stimuli.
