+**Input Lag** is the delay between a user's action (input) and the resulting visual or auditory feedback from a system. This imperceptible gap can significantly impact responsiveness, especially in time-sensitive applications like [Video Games](/wiki/video_games) or [Virtual Reality](/wiki/virtual_reality), where immediate reaction is crucial. It represents the total time taken for an input to register and manifest as output.
