What unit is ns?

ns is the time unit nanosecond. Light travels in a vacuum for only 3 centimeters in a nanosecond, and it takes about 2 to 4 nanoseconds for a microprocessor of a personal computer to execute an instruction such as adding two numbers. The existence time of another rare subatomic particle, the K meson, is 12 nanoseconds, and nanosecond ns is a very small unit of time.

the nature of ns nanosecond

nanosecond is also a technical term in computer, and it is a running unit used to calculate the running speed of CPU and various hardware. One nanosecond is equal to .1 second, and ns nanosecond is usually used to indicate the access speed of physical memory and video memory. The smaller its value, the higher the limit working frequency. For sprinters, it seems a little too long to count in seconds.

microsecond is also not the smallest unit of time. There is nanosecond below it, which is one billionth of a second, and femtosecond below nanosecond, which is one billionth of a trillion seconds, which is equal to 1 to the negative 9th power second. It is often used as a unit of memory reading and writing speed. The smaller the number in front of it, the faster it is.
