The Graphic Interchange Format is a bitmap image format that was introduced by CompuServe in 1987. The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to 256 distinct colors. The colors are chosen from the 24-bit RGB color space. It also supports animation and allows a separate palette of 256 colors for each frame.
GPS:
Global Positioning System. The GPS receiver uses satellites to let you determine the exact longitude, latitude and height above sea level anywhere on earth.
Graphics Card:
Component of a computer that is necessary to display an image on the monitor screen.
Grey scale:
A scale of shades ranging from white to black. Devices that can only display data in black and white translate color difference into various shades of grey.
GSM:
Global System for Mobile telecommunication. Standard for the transfer of data by mobile phone.
Guide Number (GN):
Value for the maximum power of a camera flash based on a flim with an ISO of 100. Built-in camera flashes have a guide number of approx. 10-20, compact flashes between 20-40, and the GN for grip-type flashes is between 45-60.
