   All of the mice have a polling rate of 1000 Hz. The polling rate of a mouse is how many often it notifies the computer of its location each second, with each Hz equaling one register. [22] In November 2017, Razer introduced the Naga Trinity. This mouse has interchangeable side panels, meaning the user could choose how many buttons they wanted.

   The keyboard sends the key code to the keyboard driver running in the main computer; if the main computer is operating, it commands the light to turn on. All the other indicator lights work in a similar way. The keyboard driver also tracks the shift, alt and control state of the keyboard.

9. Asynchronous I/O - Wikipedia

   en.wikipedia.org/wiki/Asynchronous_I/O

   Every CPU cycle that is a poll is wasted, and lost to overhead rather than accomplishing a desired task. Every CPU cycle that is not a poll represents an increase in latency of reaction to pending I/O. Striking an acceptable balance between these two opposing forces is difficult. (This is why hardware interrupt systems were invented in the ...
