  • 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.

  • vCPE (virtual customer premises equipment)

    Virtual customer premises equipment (also referred to as vCPE or cloud CPE) are enterprise network services delivered through software. While providers must manually deploy traditional, physical CPE devices onsite, they can provision and manage vCPE remotely.

  • vEPC (virtual Evolved Packet Core)

    The vEPC offers a framework to support converged voice and data on 4G Long-Term Evolution networks. vEPC is the abstraction of Evolved Packet Core components into software that runs on generic servers, potentially cutting costs and improving service delivery.

  • 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.

  • video on demand (VoD)

    Video on demand (VoD) is an interactive TV technology that allows subscribers to view programming in real time or download programs and view them later... (Continued)

  • 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 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.
