CSMA/CD
     
        Carrier Sense Multiple Access / Collision Detect.
     
        The low level network arbitration {protocol} used on
        {Ethernet}.  Nodes wait for quiet on the net before starting
        to transmit and listen while they are transmitting.  If two
        nodes transmit at once the data gets corrupted.  The nodes
        detect this and continue to transmit for a certain length of
        time to ensure that all nodes detect the collision.  The
        transmitting nodes then wait for a random time before
        attempting to transmit again thus minimising the chance of
        another collision.  The ability to detect collision during
        transmission reduces the amount of {bandwidth} wasted on
        collisions compared with simple {ALOHA} broadcasting.
