Patch

A patch is a small change made to computer software, usually to fix a minor bug, which is distributed in leu of releasing a whle new version of the original program. Because patch files are usually quite small, it is practical to release them over the Internet or through computer bulletin boards.

Patches are sometimes created by the original software vendor, and sometimes by interested third parties. A patch file set may include a small program which actually implements the patch automatically, or it may include detailed instructions on making the changes by hand.

A patch which is not 100% effective or which is considered temporary (while a better fix is being sought) is sometimes called a workaround.
