         Carrier Sense Multiple Access with Collision Detection (IEEE
  802.3, ethernet, CSMA/CD), "CSMA/CD"

From The Free On-line Dictionary of Computing (30 December 2018) :

     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.
