Brightness can be defined as the intensity of the light coming from a source, for instance, the display of a laptop, smartphone, TV, or other devices.
It comes from the adjective bright, meaning something that reflects light, that is shining. Brightness tells us how much light is radiated from a source and is measured in candelas.
In computing, almost any device that has a display features a setting called brightness, that can be modified by the user as he likes. It can be a physical button or a software option.
