In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action.. In video games the term is often used to describe any latency between input and the game engine, monitor, or any other part of the signal chain reacting to that input, though all contributions of input lag are cumulative.
Display lag contributes to the overall latency in the interface chain of the user's inputs (mouse, keyboard, etc.) to the graphics card to the monitor. Depending on the monitor, display lag times between 10-68 ms have been measured. However, the effects of the delay on the user depend on each user's own sensitivity to it.
They also have a lower (albeit practically imperceptible) input latency, which results in a slightly more responsive button input and a more stable connection. They also don’t require batteries.
This may be a few keystrokes due to reaction time, or may be more if the user's attention is not on the computer screen, e.g. typing while looking at the keyboard or while reading copy to the side, or if processor lag causes a delay (sometimes of several seconds) between the focus stealing event and the newly focused window displaying on the ...
The extra input lag can also make it very difficult to play certain single player games. For example, if an enemy takes a swing at the player and the player is expected to block, then by the time the player's screen shows that the enemy has commenced attacking, the enemy would have already struck and killed the player on the server.
Keyboard shortcuts make it easier and quicker to perform some simple tasks in your AOL Mail. Access all shortcuts by pressing shift+? on your keyboard. All shortcuts are formatted for Windows computers, but most will work on a Mac by substituting Cmd for Ctrl or Option for Alt. General keyboard shortcuts
That said, display lag is certainly a consideration for non-interactive sources (e.g. video, television), but the display lag manifests itself as an annoying human problem /MAINLY/ if there's interactivity (human doing input, e.g. keyboard or mouse), therefore "Input Lag" is a possibly a MORE accurate title for this article, provided the ...
