  96. What does csma/cd stand for?
    Carrier Sense Multiple Access/Collision Avoidance
  97. How many hosts can transmit per segment for a csma/cd  network?
    1
  98. What steps does each host take in order to transmit on a csma/cd network?
    ·         The host must wait for the line to be clear before transmitting·         When the line is clear, the host will transmit·         If two hosts assume the line is clear and both send at the same time, it creates a collision.·         When a collision occurs:o   The two parties send a jam signal to the rest of the hosts which initiates a “back-off algorithm” sequenceo   The back-off algorithm sequence tells each host to pick a random amount of time before transmitting againo   Each host will wait the random amount of time and the start the process over again.
