A patch is usually intended to modify an executable file to improve it.
A patch is obviously a digitalized file which has been programmed to take out programming faultys and errors and replace them with a correct line of code.
A patch can be written by any programmer with a open source executable file (that they wish to modify). Patches can also be written by programmers to convert trial softwares to full version softwares, this includes games. The word for adding patches to executable files to modify it illegally is called, when spoken by someone "patched". Look below

Gekotec: Oh, boy.
