How do we measure time?
Millisecond (ms or msec):
Commonly used in measuring the time to read to, or write from, a
hard disk or a CD-ROM player. Also used to measure packet travel
time on the Internet.
Microsecond (μs or μsec):
Commonly used to measure intra-switch latency, cache latency,
and the time it takes light to traverse an optical link or electricity to
traverse a copper link.
Nanosecond (ns or nsec):
Common measurement of the read or write access time to random
access memory (RAM).
Measurement sometimes used in laser technology.
A term used in photon research.
