From WordNet (r) 3.0 (2006) [wn]:

From The Free On-line Dictionary of Computing (15Feb98) [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}.
