  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
    A  {host}  which  has  experienced  a  {collision}  on  a 
  {network}  waits  for  a  amount  of  time  before  attempting  to 
  retransmit.  A  random  backoff  minimises  the  probability  that 
  the  same  nodes  will  collide  again  even  if  they  are  using  the 
  same  backoff  algorithm.  Increasing  the  backoff  period  after 
  each  collision  also  helps  to  prevent  repeated  collisions, 
  especially  when  the  network  is  heavily  loaded. 
  An  example  algorithm  is  {binary  exponential  backoff}.
