Abbreviation for Virtual Direct Memory Access Services.

9(6$Š

Acronym for Video Electronics Standards Association.

9*$

Abbreviation for video graphics array. VGA and SVGA are video standards for video adapters with greater resolution and color display capabilities than EGA and CGA, the 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 mem- ory installed for 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 connector.

YLGHR￿DGDSWHU

The logical circuitry that provides—in combination with the monitor or display— your computer’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 displaying popular application programs and operating envi- ronments in a variety of video modes.

On most current 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 can include memory sep- arate 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

simultaneously displayed. Video adapters can also include their own coprocessor chip for faster graphics rendering.

YLGHR￿GULYHU

Graphics-mode application programs and operating environments, such as Win- dows, often require video drivers in order to display at a chosen resolution with the desired number of colors. A program may include some “generic” video drivers. Any additional video drivers may need to match the video adapter; you can find these drivers on a separate diskette with your computer or video adapter.

YLGHR￿PHPRU\

Most VGA and SVGA video adapters in- clude VRAM or DRAM memory chips in addition to your computer’s RAM. The amount of video memory installed prima- rily influences the number of colors that a program can display (with the appropriate video drivers and monitor capability).

YLGHR￿PRGH

Video adapters normally support multiple text and graphics display modes. Charac- ter-based software (such as MS-DOS) displays in text modes that can be defined as x columns by y rows of characters. Graphics-based software (such as Win- dows) displays in graphics modes that can be defined as x horizontal by y vertical pixels by z colors.

YLGHR￿UHVROXWLRQ

Video resolution—640 x 480, 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.

YLUWXDO￿￿￿￿￿￿PRGH

An operating mode supported by Intel386 or higher microprocessors, virtual 8086 mode allows operating environments— such as Windows—to run multiple pro- grams in separate 1-MB sections of memory. Each 1-MB section is called a virtual machine.
