Validate:
In the context of this
document, to confirm or ensure well
grounded logic, and true and accurate
determinations.
VAR/VAD/VASD:
ValueAdded Reseller/ValueAdded
Dealer/ValueAdded Specialty
Distributor. Companies or people who
sell computer hardware or software and
“addvalue” in the process. Usually, the
value added is specific technical or
marketing knowledge and/or experience.
VDT (Video Display
Terminal):
Generic name for all
display terminals.
Vector:
Representation of graphic
images by mathematical formulas. For
instance, a circle is defined by a
specific position and radius. Vector
images are typically smoother than
raster images.
VendorAdded Metadata:
Data created and
maintained by the electronic discovery
vendor as a result of processing the
document. While some vendoradded
metadata has direct value to customers,
much of it is used for process
reporting, chain of custody and data
accountability. Contrast with UserAdded
Metadata.

Metadata.
Verbatim Coding:
Extracting data from
documents in a collection in a way that
matches exactly as the information
appears in the documents.
Version, Record Version:
A particular form or
variation of an earlier or original
record. For electronic records the
variations may include changes to file
format, metadata or content.
Vertical DeDuplication:
A process through which
duplicate documents/data are eliminated
within a single custodial or production
data set.

Deduplication, Metadata Comparison, and
Near DeDuplication.
VGA (Video Graphics
Adapter):
A PC industry standard,
first introduced by IBM in 1987, for
color video displays. The minimum dot
(pixel) display is 640 by 480 by 16
colors. Then “Super VGA” was introduced
at 800 x 600 x 16, then 256 colors. VGA
can extend to 1024 by 768 by 256 colors.
Replaces EGA, an earlier standard and
the even older CGA. Newer standard
displays can range up to 1600 by 1280.
Video Electronics Standards Association
(VESA):
Concentrates on computer
video standards.
Video Scanner Interface:
A type of device used to
connect scanners with computers.
Scanners with this interface require a
scanner control board designed by Kofax,
Xionics or Dunord.
Virus:
A selfreplicating
program that spreads by inserting copies
of itself into other executable code or
documents. A program into which a virus
has inserted itself is said to be
infected, and the infected file (or
executable code that is not part of a
file) is a host. Viruses are a kind of
malware (malicious software). Viruses
can be intentionally destructive, for
example by destroying ESI, but many
viruses are merely annoying. Some
viruses have a delayed payload,
sometimes referred to a bomb. The
primary downside of viruses is
uncontrolled selfreproduction, which
desecrates or engulfs computer
resources.
Vital Record:
A record that is
essential to the organization’s
operation or to the reestablishment of
the organization after a disaster.
VoIP (Voice over Internet
Protocol):
Telephonic capability
across an IP connection; increasingly
used in place of standard telephone
systems.
Volume:
A volume is a specific
amount of storage space on computer
storage media such as hard drives,
floppy discs, CDROM discs, etc. In some
instances, computer media may contain
more than one volume, while in others,
one volume may be contained on more than
one disc.
Volume Boot
Sector/Record:
When a partition is
formatted to create a volume, a volume
boot sector is created to store
information about the volume. One volume
contains the operating system and its
volume boot sector contains code used to
load the operating system when the
computer is booted up.
See
Partition.
VPN (Virtual Private
Network):
A secure network that is
constructed by using public wires to
connect nodes. For example, there are a
number of systems that enable creation
of networks using the Internet as the
medium for transporting data. These
systems use encryption and other
security mechanisms to ensure that only
authorized users can access the network
and that the data cannot be intercepted.
