  • V

    V.90

    V.90 is a A Tour of the Internet, Who Runs It, Standards Org, approved by the International Telecommunications Union (ITU-TS), for transmitting data downstream to modems at 56 Kbps (thousand bits per second).

  • V.xx

    The V Series Recommendations from the ITU-TS are summarized in the table below.

  • value-added network (VAN)

    A value-added network (VAN) is a private network provider (sometimes called a turnkey communications line) that is hired by a company to facilitate electronic data interchange (EDI) or provide other network services.

  • vampire tap

    A vampire tap is a connection to a coaxial cable in which a hole is drilled through the outer shield of the cable so that a clamp can be connected to the inner conductor of the cable.

  • variable-length subnet mask (VLSM)

    Definition: Learn what a variable-length subnet mask (VLSM) is and how it allows network engineers to reduce the number of wasted IP addresses in each subnet.

  • varicode

    Varicode is a method of binary character encoding in which the number of bits for each character is not fixed, but varies for each character depending on how often that character occurs in general usage.

  • vBNS (very high-speed Backbone Network Service)

    The vBNS (very high-speed Backbone Network Service) is a network that interconnects a number of supercomputer centers in the United States and is reserved for science applications requiring the massive computing that supercomputers can provide.

  • Veronica

    Veronica is a program that allowed you to search the files of the Internet's Gopher servers for a particular search string.

  • VHF (very high frequency)

    The VHF (very high frequency) range of the radio spectrum is the band extending from 30 MHz to 300 MHz.

  • virtual area network (VAN)

    A virtual area network (VAN) is a network on which users are enabled to share a more visual sense of community through high band-width connections.

  • virtual circuit

    A virtual circuit is a circuit or path between points in a network that appears to be a discrete, physical path but is actually a managed pool of circuit resources from which specific circuits are allocated as needed to meet traffic requirements.

  • virtual LAN (VLAN)

    A virtual local area network (virtual LAN) lets network nodes that are geographically dispersed communicate as if they physically resided on the same network.

  • virtual network adapter

    A virtual network adapter is a program (instead of a physical network adapter) that allows a computer to connect to a network. A virtual network adapter can also be used to connect all the computers on a local area network (LAN) to a larger network such as the Internet or a collection of LANs.

  • virtual network computing (VNC)

    Virtual network computing (VNC) is a type of remote-control software that makes it possible to control another computer over a network connection...

  • virtual private LAN service (VPLS)

    Virtual private LAN service (VPLS) is a technology that makes it possible to connect geographically dispersed local area networks (LANs) logically over the Internet.
