| In some operating system's file systems, a data file
over a certain size is stored in several "chunks" or fragments
rather than in a single contiguous sequence of bits in one place on the
storage medium, a process that is called fragmentation. This allows small
unused sections of storage (for example, where old data has been deleted)
to be reused. In the Windows 95 system, for example, files are fragmented
and the location of the fragments for each file is kept in a file allocation
table (FAT). |
