Patch - Computer Definition

Patch:

We all know games and applications aren’t perfect. When they are released we would hope that they have been thoroughly tested for bugs and incompatibility problems, but you can guarantee that many of these will still slip through the quality control net.

Once the program is released to the general public, the bug reports start to flood in. A patch is a downloadable executive file which takes these reports into account and attempts to incorporate all the fixes for these known problems. A patch can resolve incompatibility problems, prevent crashes or improve the performance of a piece of software.
