collision occurs during the first 512 bits of the frame transmission.  If a collision occurs after the 512
bit times, then it is considered a late collision.  A late collision should be taken as a serious network
problem, since it causes the frame being transmitted to be discarded.  The most common cause of
late collisions is a mismatch between duplex configurations at each end of a link segment.
