Hack

1. In modern computing terminology, a "kludge" (or often a "hack") is a solution to a problem, the performance of a task, or a system fix which is inefficient, inelegant ("hacky"), or even incomprehensible, but which somehow works. It is similar to a workaround, but quick and ugly.
2. A hack is a modification of hardware and/or firmware to perform a function it wasn't necessarily design to do
