100millisecond

100 milliseconds (100 ms) is a unit of time equal to one tenth of a second. The millisecond is the SI unit for time in decimal fractions of a second. In practical terms, 100 ms is a brief interval commonly used to measure delays, response times, or processing windows in computing and electronics.

In computing and networks, 100 ms represents a typical latency scale. For interactive applications and online services, end-to-end latency around or below 100 ms is often cited as desirable for responsiveness. In fast networks, round-trip times can approach or fall under this range, while in more distant connections they are typically longer.

In human-computer interaction and usability, roughly 100 ms is a practical threshold for perceived instantaneous feedback. Delays shorter than this are often perceived as immediate, while longer delays tend to be noticed as lag, affecting user experience and task performance.

In display and gaming contexts, 100 ms corresponds to about six frame intervals on a 60 Hz display and about twelve frames on a 120 Hz display. This framing helps relate latency to visual smoothness and interactivity, informing design choices for interactive applications and real-time systems.

In other technical domains, 100 ms is sometimes used as a sampling window, debounce interval, or processing bucket in digital signal processing and electronic circuits. Its usage reflects its role as a convenient, perceptible but still brief time scale.
