  From  WordNet  r  1.6  [wn]: 
 
  segment 
  n  1:  one  of  several  pieces  or  parts  that  fit  with  others  to 
  constitute  a  whole  object:  "a  section  of  a  fishing  rod";

  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  segment  /seg'ment/  vi  To  experience  a  {segmentation  fault}. 
  Confusingly,  this  is  often  pronounced  more  like  the  noun  `segment' 
  than  like  mainstream  v.  segment;  this  is  because  it  is  actually  a  noun 
  shorthand  that  has  been  verbed. 
 
 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  segment 
 
  /seg'ment/  1.    A  collection  of  {pages}  in  a 
  {memory  management}  system. 
 
  2.    A  separately  relocatable  section  of  an 
  executable  program.  {Unix}  executables  have  a  {text  segment} 
  (executable  machine  instructions),  a  {data  segment} 
  (initialised  data)  and  a  {bss  segment}  (uninitialised  data). 
 
  3.    {network  segment}. 
 
  4.  To  experience  a  {segmentation  fault}.  Confusingly,  the  stress 
  is  often  put  on  the  first  syllable,  like  the  noun  "segment", 
  rather  than  the  second  like  mainstream  verb  "segment".  This 
  is  because  it  is  actually  a  noun  shorthand  that  has  been 
  verbed.
