CSMA/CD
Workstation wants to transmit some data
  1. Listens to see if anyone else is transmitting, if it is all clear then...
  2. Data is transmitted onto the communications channel
  3. Workstation listens to its own message to see if there was a collision
  4. No collision? then process finished
  5. If there is a collision, workstation waits a random period of time then returns to step 1.
