I have run across the term Journalised and Journalised FS.ext3.
Would someone please tell me what they are and how they are used?
Thanks,

Ok, FS means filesystem, which is the method that the linux kernel
stores files to the hard drive. Depending on which filesystem you have,
your computer will save files, keep track of files, move them around,
etc, differently. On normal ext2 filesystems (not journalized), records
are not kept of hard drive activity. This means that if you lose power
or the computer is not cleanly shut down, it may take a LONG time for
the computer to restore itself. With a journalized FS, after the power
loss, the computer can restore the filesystem structure quite easily.
Ext3 is a type of Journalized FS. Other kinds of Journalized FS's
include XFS, JFS, ReiserFS, and Reiser4 (still in development, but 50%
faster than the others).
If I did a crummy job of explaining this, maybe someone else could help
me out.
