Nanoseconds
A nanosecond, symbol ns, is a unit of time equal to one billionth of a second. As an SI derived unit, it is commonly used to express very short time intervals in science, engineering, and technology. By definition, one nanosecond equals 10^-9 seconds, and there are 1,000,000,000 nanoseconds in a second.
In practical terms, a nanosecond denotes extremely brief intervals. Light travels about 0.2998 meters (approximately 29.98
Nanoseconds are widely used to describe processor clock cycles, memory latencies, and timing resolutions in digital
Measurement and standards: timekeeping relies on atomic clocks that define the second, while specialized instruments such
Etymology and context: the term nanosecond combines nano-, meaning one billionth, with second. The concept gained
