Networking Definitions

  • B

    balun

    A balun is a device that joins a balanced line (one that has two conductors, with equal currents in opposite directions, such as a twisted pair cable) to an unbalanced line (one that has just one conductor and a ground, such as a coaxial cable).

  • band

    In telecommunication, a band - sometimes called a frequency band - is a specific range of frequencies in the radio frequency (RF) spectrum, which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf).

  • baseband

    Describes a telecommunication system in which information is carried in digital form on a single unmultiplexed signal channel on the transmission medium.

  • baseboard management controller (BMC)

    A baseboard management controller (BMC) is a specialized service processor that monitors the physical state of a computer, network server or other hardware device using sensors and communicating with the system administrator through an independent connection... (continued)

  • Basic Rate Interface (BRI)

    In the Integrated Services Digital Network (ISDN), there are two levels of service: the Basic Rate Interface (BRI), intended for the home and small enterprise, and the Primary Rate Interface (PRI), for larger users.

  • baud

    Baud was the prevalent measure for data transmission speed until replaced by a more accurate term, bps (bits per second).

  • beamforming

    Beamforming is a type of RF (radio frequency) management in which an access point uses multiple antennas to send out the same signal.

  • Bearer Independent Call Control (BICC)

    Bearer Independent Call Control (BICC) is a signaling protocol based on N-ISUP that is used to support narrowband ISDN service over a broadband backbone network without interfering with interfaces to the existing network and end-to-end services.

  • Bel

    In electronics and communications, the Bel expresses the logarithmic ratio between two levels of signal power, voltage, or current.

  • Bellcore (Bell Communications Research)

    Bellcore (Bell Communications Research) provides certain centralized research and standards coordination for the regional Bell operating companies (RBOC)s.

  • BGAN (Broadband Global Area Network)

    BGAN (Broadband Global Area Network) is a mobile communications system created to transmit broadband wireless voice and data communications almost anywhere on the earth's surface.

  • big-endian and little-endian

    Big-endian and little-endian are terms that describe the order in which a sequence of bytes are stored in computer memory.

  • bit rate

    In digital telecommunication, the bit rate is the number of bits that pass a given point in a telecommunication network in a given amount of time, usually a second.

  • bit robbing

    Bit robbing is a technique used in signaling on the T-carrier system, the widely-used system for transmitting both voice and data in digital form in the public switched telephone network (PSTN) and in private networks.

  • bit stream

    A bit stream is a contiguous sequence of bits, representing a stream of data, transmitted continously over a communications path, serially (one at a time).
