  2. Microsecond - Wikipedia

    en.wikipedia.org/wiki/Microsecond

    2.68 microseconds – the amount of time subtracted from the Earth's day as a result of the 2004 Indian Ocean earthquake. [2] 3.33564095 microseconds – the time taken by light to travel one kilometre in a vacuum. 5.4 microseconds – the time taken by light to travel one mile in a vacuum (or radio waves point-to-point in a near vacuum).

  5. Nanosecond - Wikipedia

    en.wikipedia.org/wiki/Nanosecond

    A nanosecond is to one second, as one second is to approximately 31.69 years. A nanosecond is equal to 1000 picoseconds or ⁠ 1 / 1000 ⁠ microsecond. Time units ranging between 10 −8 and 10 −7 seconds are typically expressed as tens or hundreds of nanoseconds. Time units of this granularity are commonly found in telecommunications ...

  7. Bit time - Wikipedia

    en.wikipedia.org/wiki/Bit_time

    The bit time for a 10 Mbit/s NIC is 100 nanoseconds. That is, a 10 Mbit/s NIC can eject 1 bit every 0.1 microsecond (100 nanoseconds = 0.1 microseconds). Bit time is distinctively different from slot time, which is the time taken for a pulse to travel through the longest permitted length of network medium.

  8. TU (time unit) - Wikipedia

    en.wikipedia.org/wiki/TU_(Time_Unit)

    In some data communication standards, a time unit (TU) is equal to 1024 microseconds. [1] This unit of time was originally introduced in IEEE 802.11-1999 standard [2] and continues to be used in newer issues of the IEEE 802.11 standard. [1] In the 802.11 standards, periods of time are generally described as integral numbers of time units.

  9. Propagation delay - Wikipedia

    en.wikipedia.org/wiki/Propagation_delay

    An electromagnetic wave travelling through a medium has a propagation delay determined by the speed of light in that particular medium, or ca. 1 nanosecond per 29.98 centimetres (11.80 in) in a vacuum. An electric signal travelling through a wire has an propagation delay of ca. 1 nanosecond per 15 centimetres (5.9 in). [1]
