    binary
  19. Assignment of one network component to work with another network component.
    binding
  20. A file compression standard for MAC, which allows several file types to be combined into one unit. These files have an HQX extension.
    BinHex
  21. Basic Input/Output System which controls the communication between hardware devices. The BIOS is the firmware on the computers motherboard.
    BIOS
  22. A binary digit that can be a 0 or 1, equal to an on or an off signal.
    bit
  23. What does BERT stand for?
    Bit-Error Rate Test
  24. A mathematical operation used to determine the network and node portions of an IP address.
    Bitwise Boolean AND
  25. A term used to describe the area around a printed document. Typically the bleed is 1/8th of an inch.
    bleed
  26. The manufacturer portion of the MAC address, which includes the first set of 6 characters.
    Block ID
  27. A wireless protocol capable of creating personal area networks, from fixed and mobile devices over short distances. Bluetooth uses frequency hopping spread spectrum which breaks the data up and transmits over 79 frequencies.
    Bluetooth
  28. Abbreviation for British Naval Connector or Bayonet Nut Connector, a tubular connector used for coaxial cable.
    BNC
  29. The combination of multiple bearer channels of an ISDN line to increase bandwidth.
    bonding
  30. The physical division of a disk that is marked bootable. This is the first partition in which an operating system searches for the files to boot the system.
    boot partition
  31. A virus that affects the startup of the operating system. Common errors when there is a boot sector virus include "Missing Operating Disk" or "Hard Disk not found".
    boot sector virus
  32. A file accessed by an operating system to determine the operating system options to display during the startup or boot process.
    BOOT.INI
  33. What is BOOTP?
    Acronym for Bootstrap Protocol, used by a computer to find out its configuration information from a host.
  34. What does BGP stand for?
    Border Gateway Protocol
  35. A software application capable of running an automated task over the internet.
    bot
  36. Hardware or software that places limits on the production of a device or network due to its inability to handle its required workload.
    bottleneck
  37. Similar to a proxy it is used to relay traffic and network connections.
    bounce
  38. Is used to shield a cable from electromagnetic interference.
    braiding
  39. What is BRI?
    Acronym for Basic Rate Interface, an ISDN interface composed of two B channels and one D channel for circuitswitched communication of voice, video, and data.
  40. A device that separates a network into segments at the data link layer, although the segments still appear as one network to upper level protocols.
    bridge
  41. What does BNC stand for?
    British Naval Connector
  42. A data transmission method that divides a single transmission medium, so multiple signals can travel at the same time. (See also baseband.)
