  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  fragmentation 
 
  1.    {segmentation}. 
 
  2.  The  process,  or  result,  of  splitting  a  large  area  of  free 
  memory  (on  disk  or  in  main  memory)  into  smaller  non-contiguous 
  blocks.  This  happens  after  many  blocks  have  been  allocated 
  and  freed.  For  example,  if  there  is  3  kilobytes  of  free  space 
  and  two  1k  blocks  are  allocated  and  then  the  first  one  (at  the 
  lowest  address)  is  freed,  then  there  will  be  2k  of  free  space 
  split  between  the  two  1k  blocks.  The  maximum  size  block  that 
  could  then  be  allocated  would  be  1k,  even  though  there  was  2k 
  free  The  solution  is  to  compact"  the  free  space  by  moving 
  the  allocated  blocks  to  one  end  (and  thus  the  free  space  to 
  the  other).  See  {garbage  collection}.
