Milliseconds

The millisecond is a unit of time equal to one thousandth of a second (10⁻³ s) and represents the timescale of human physiological responses and digital audio. The human minimum reaction time to a visual stimulus is approximately 150–200 milliseconds. Network latency in internet communications is measured in milliseconds, where values below 20 ms are considered excellent for real-time applications.

Nanoseconds

The nanosecond is a unit of time equal to one billionth of a second (10⁻⁹ s) and is the operational timescale of modern digital electronics. A 3 GHz processor executes approximately one clock cycle every 0.33 nanoseconds. The propagation of electrical signals through circuits, memory access times, and network packet transmission are all measured in nanoseconds. Light travels approximately 30 cm in one nanosecond.
