vaccine - a computer program which protects
your computer from or rids your computer of viruses.
vaporware - software that does not exist
and never will. See SF.
variable - a value which can change, or the
name given to a location in memory used to store variable data. See string,
local variable, global
variable, property, instance
VAX - a once-popular line of mini-computer and
workstations from DEC. See VMS,
VAXen - the plural of VAX.
VB - See Visual Basic
VC - Viet Cong.
vector - 1. the carrier or transmitter of a
disease, as in, "a mosquito is the vector for malaria". See daycare.
2. a quantity possessing both magnitude and direction. 3. a line drawn between
two points. Multiple vectors are used to draw more complicated shapes. See
vector-based - a vector-based graphic
stores specific coordinates that can be used to reconstruct the graphic,
not each and every pixel. For example, a rectangle can be defined by two
opposite corners. Although less memory-intensive than comparable pixel-based
graphics, these may be drawn more slowly because run-time calculations are
required. See bitmap.
Veronica - See Archie,
Betty, Gopher, Jughead.
VGA - Video
Graphics Adapter. See CGA, EGA,
VHS - a standard for video tape machines. Compare
video - see QuickTime,
and Video for Windows.
video capture - the process of digitizing
video from an external source, such as a video camera or video tape. Director
does not support video capture, but third-party Xtras may allow you to include
such functionality in your Director presentation. See capture,
screen capture. See Beta,
video driver - a driver
designed to interface with a particular video card. See DirectX,
Video for Windows - Microsoft standard
for video playback. See codec and AVI.
Video Graphics Adapter - a display
standard, supporting 256 colors at 640 x 480 resolution, commonly referred
to as VGA. See CGA, EGA,
VideoWorks - a precursor to Director.
Refer to the Director version History.
virtual memory - the use of disk space
to simulate additional RAM, also called a swap
file. Virtual memory allows you to run programs for which you would
otherwise not have sufficient RAM. Because disk access is much slower than
RAM access, virtual memory will have poor performance relative to that of
actual RAM. Refer to the TechNote, "Memory
Configurations." for instructions on configuring virtual memory.
virtual reality - 1. Uncle
Cid 2. computer-simulated reality that gives the illusion of reality.
See immersion, Brinkley,
virtual surreality - see Dali.
virus - a malevolent computer program ranging
from the merely annoying to the terribly destructive. see Disinfectant,
Symantec Anti-Virus, McAfee.
Visual C/C++ - an implementation of C/C++
from Microsoft, known as MSVC.
Visual Basic - an implementation of Basic
from Microsoft, abbreviated VB.
See Visual C/C++.
VM - 1. see Virtual
Memory. 2. Virtual Machine. See Java.
VMS - Virtual Memory System,
the operating system used on DEC VAX
computers. See VT100.
voice recognition - software and/or
hardware which allows a computer to accept voice commands. The general consensus
is that VR is not quite ready for prime time.
VR - 1. Voice
Recognition; 2. Virtual Reality.
VRAM - Video Random Access Memory - the amount
of VRAM determines how many colors and what resolution your monitor can
display. The speed of VRAM affects the speed with which the screen updates.
VT100 - a popular terminal for connecting to
VAX computers, often used as a standard in dial-up BBSes.. See terminal,
terminal emulation. Other models
in the line included VT101, VT102, and VT104.
VWPBL - Void Where Prohibited
By Law, an uncommon e-mail abbreviation
used as a generaly disclaimer. See YMMV.
