A system that pre-dates the World Wide Web for organizing and displaying files on Internet servers. A Gopher server presents its contents as a hierarchically structured list of files. With the ascendance of the Web, many gopher databases were converted to Web sites which can be more easily accessed via Web search engines.
Gopher was developed at the University of Minnesota and named after the school’s mascot. Two systems, Veronica and Jughead, let you search global indices of resources stored in Gopher systems.
Short for graphics pages per minute, the speed with which laser printers can print nontext pages. Typically, laser printers are rated in terms of pages per minute (ppm ), but this refers only to the speed with which they print text pages. The gppm is always much less and may be the more important figure […]

- graphics accelerator
A type of video adapter that contains its own processor to boost performance levels. These processors are specialized for computing graphical transformations, so they achieve better results than the general-purpose CPU used by the computer. In addition, they free up the computer’s CPU to execute other commands while the graphics accelerator is handling graphics computations. […]
