Tweaking is the process of fine-tuning complex devices, typically electronic devices. In simple words, it is a method for making small changes to fine-tune hardware or software.
Sometimes, tweaking can also refer to slightly altering the values of underlying variables so that the actual result of a program coincides with the desired outcome. In this situation, tweaking may not be the best thing, as it weakens the program's integrity.
Hardware tweaking involves adjusting specific parts of the hardware to get optimum results. For example, tweaking activities might include replacing cables, overclocking the CPU, modifying the jumper settings, improving system cooling, modifying the memory unit timing, and so on.
Software tweaking is a method of enhancing the functionality of an application or improving the quality of its end result. This can be done manually or with the help of a specialized tweaking software program. Linux and other open-source products encourage tweaking. Microsoft limits tweaking on its Windows operating system; the MAC OS strongly discourages or prohibits tweaking as well.
Some software manufacturers and developers, such as the LAME MP3 Encoder, perform continuous software tweaking to:
Tweaks are irrelevant if an application source is closed or the user does not have programming experience.
