VCCI

 

Abbreviation for Voluntary Control Council for Interference.

VDC

 

Abbreviation for volt(s) direct current.

VGA

 

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 resolution, you must install the appropriate video drivers and your monitor must support the resolution. Similarly, the

number of colors that a program can display depends on the capabilities of the monitor, the video driver, and the amount of video memory installed for the
video adapter.

video adapter

 

The logical circuitry that provides—in combination with the monitor—your system'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 systems in a
variety of video modes.

 

On some systems, 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 simultaneously displayed. Video adapters can also include their own coprocessor for faster graphics rendering.

video driver

 

A program that allows graphics-mode application 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 installed in the system.

video memory

 

Most VGA and SVGA video adapters include memory chips in addition to your system's RAM. The amount of video memory installed primarily influences the

number of colors that a program can display (with the appropriate video drivers and monitor capabilities).

video mode

 

Video adapters normally support multiple text and graphics display modes. Character-based software displays in text modes that can be defined as x columns

by y rows of characters. Graphics-based software displays in graphics modes that can be defined as x horizontal by y vertical pixels by z colors.

video resolution

 

Video resolution 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 monitor must support the resolution.

VRAM

 

Abbreviation for video random-access memory. Some video adapters use VRAM chips (or a combination of VRAM and DRAM) to improve video performance.

VRAM is dual-ported, allowing the video adapter to update the screen and receive new image data at the same time.

W

 

Abbreviation for watt(s).

WH

 

Abbreviation for watt-hour(s).

win.ini file

 

A start-up file for the Windows operating system. When you start Windows, it consults the win.ini file to determine a variety of options for the Windows

operating environment. Among other things, the win.ini file records what printer(s) and fonts are installed for Windows. The win.ini file also usually includes
sections that contain optional settings for Windows application programs that are installed on the hard drive.

 

Running the Control Panel or Windows Setup program may change options in the win.ini file. On other occasions, you may need to change or add options to

the win.ini file manually with a text editor such as Notepad.

Windows.NET

 

A set of Microsoft software technologies that enable software integration through the use of XML Web services. XML Web services are small reusable

applications written in XML that allow data to be communicated between otherwise unconnected sources.

Windows 2000

 

An integrated and complete Microsoft Windows operating system that does not require MS-DOS and that provides advanced operating system performance,

improved ease of use, enhanced workgroup functionality, and simplified file management and browsing.
