| Ability
of a hardware device or software program that prevents or allows data to
be written to it.
For example, to protect a file in
software, users utilizing Microsoft
MS-DOS could write protect a file utilizing the attrib
command; users using a Linux variant or Unix variant could write
protect a file utilizing the chmod
command.
To protect a file with a hardware
device such as a floppy diskette, users using a 5.25-inch floppy
diskette can write protect a diskette by covering a notch with tape at
the upper corner of the diskette; users using a 3.5-inch diskette can
enable or disable write protection by moving a small tab to block or
unblock the hole located in the corner of the floppy diskette.
By using write protection, users have
the ability to help ensure data is not accidentally overwritten or
erased.
