  1. backoff algorithm
    the retransmission delay used with CSMA/CD when a collision occurs. The algorithm forces each sender that detected the collisions to delay a random amount of time before attempting to retransmit.
  2. bandwidth
    In networking, a measurement of the speed of bits that can be transmitted over a particular link. It is the amount of data that can be transmitted in a certain amount of time. For digital bandwidth it is usually expressed in bits per second.
  3. best effort
    network protocols or technologies that do not use the acknowledgment system to guarantee reliable delivery of information
  4. binary
    a numbering system characterized by 1 and 0
  5. bit
    binary digit used in the binary numbering system. Binary digits are units of information storage and communication in computing. Each bit can be either a 0 or a 1.
  6. bit time
    the time required to send a single bit over some transmission medium. The time can be calculated at 1/speed, where speed is the number of bits per second sent over the medium
  7. bridge
    a device that connects multiple network segments at the data link layer of the OSI model. Bridges were the predecessor to LAN switches.
  8. bridge table
    the table used by a switch or bridge that associates MAC addresses with the outgoing port. The switch or bridge uses this table for its forwarding/filtering decisions.
  9. bridging
    the process of forwarding frames in a switch or a bridge from one port to another port or from segment to segment
  10. broadcast
    a form of transmission where one device transmits to all devices within the network or on another network
  11. broadcast address
    an address used to represent a transmission from one device to all devices. In ethernet, the sepcial ethernet address FFFF.FFFF.FFFF is used as a destination MAC address to cause a frame to be sent to all devices on an ethernet LAN. In IPV4, each subnet has a single broadcast address, which is more commonly called the subnet or directed broadcast address.
  12. broadcast domain
    a logical network composed of all the computers and networking devices that can be reached by sending a frame to the data link layer broadcast address.
  13. burned in address
    the MAC address that is permanently assigned to a LAN interface or NIC. It is called burned-in because the address is burned into a chip on the card, and the address cannot be changed. Also called universally administered address.
