Abbreviation for video graphics array. VGA and SVGA are video standards for video adapters with greater resolution and color display capabilities than previous standards.

To display a program at a specific resolu- tion, you must install the appropriate video drivers and your monitor must sup- port the resolution. Similarly, the number of colors that a program can display de- pends on the capabilities of the monitor, the video driver, and the amount of video memory9*$IHDWXUHinstalledFRQQHFWRUfor the video adapter.

On some systems with a built-in VGA video adapter, a VGA feature connector allows you to add an enhancement adapt- er, such as a video accelerator, to your computer. A VGA feature connector can also be called a VGA pass-through

The logical circuitry that provides—in combination with the monitor—your com- puter’s video capabilities. A video adapter may support more or fewer features than a specific monitor offers. Typically, a video adapter comes with video drivers for dis- playing popular application programs and

operating systems in a variety of video modes.

On some Dell computers, a video adapter is integrated into the system board. Also available are many video adapter cards that plug into an expansion-card connector.

Video adapters often include memory separate from RAM on the system board. The amount of video memory, along with the adapter’s video drivers, may affect the number of colors that can be simulta- neously displayed. Video adapters can also include their own coprocessor for YLGHRfaster graphicsGULYHUrendering.

Aprogram that allows graphics-mode ap- plication programs and operating systems to display at a chosen resolution with the desired number of colors. A software package may include some “generic” video drivers. Any additional video drivers may need to match the video adapter in- YLGHRPHPRU\stalled in the computer.

Most VGA and SVGA video adapters in- clude memory chips in addition to your computer’s RAM. The amount of video memory installed primarily influences the number of colors that a program can dis- play (with the appropriate video drivers YLGHRand monitorPRGHcapabilities).

Video adapters normally support multiple text and graphics display modes. Charac- ter-based software displays in text modes that can be defined as x columns by y rows of characters. Graphics-based soft- ware displays in graphics modes that can be defined as x horizontal by y vertical pix-

Video resolution—800 x 600, for exam- ple—is expressed as the number of pixels across by the number of pixels up and down. To display a program at a specific graphics resolution, you must install the appropriate video drivers and your moni- tor must support the resolution.
