A polling rate of 100 Hz means that a device (such as a mouse, keyboard, or game controller) reports its state to a computer 100 times per second. This translates to a polling interval of 10 milliseconds (ms), as you can calculate it using the formula:
\[ \text{Polling interval} = \frac{1}{\text{Polling rate in Hz}} \times 1000 \]
So in this case:
\[ \text{Polling interval} = \frac{1}{100} \times 1000 = 10 \text{ ms} \]
This means that every 10 milliseconds, the device is updating its status and sending that information to the computer. A 100 Hz polling rate is generally considered adequate for most everyday applications, including casual gaming and office tasks, though higher polling rates (like 250 Hz, 500 Hz, or even 1000 Hz) are commonly preferred in more demanding gaming scenarios for better responsiveness and accuracy.
