  2. Hard disk drive performance characteristics - Wikipedia

    It depends on the rotational speed of a disk (or spindle motor), measured in revolutions per minute (RPM). [5] [23] For most magnetic media-based drives, the average rotational latency is typically based on the empirical relation that the average latency in milliseconds for such a drive is one-half the rotational period.

  3. Latency (engineering) - Wikipedia

    en.wikipedia.org/wiki/Latency_(engineering)

    Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games. [1]

    en.wikipedia.org/wiki/Access_time

    Access time is the time delay or latency between a request to an electronic system, and the access being initiated or the requested data returned.. In computer and software systems, it is the time interval between the point where an instruction control unit initiates a call to retrieve data or a request to store data, and the point at which delivery of the data is completed or the storage is ...

  6. Network delay - Wikipedia

    en.wikipedia.org/wiki/Network_delay

    It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. [1] [2]: 5 It is typically measured in multiples or fractions of a second. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints.

  9. Network performance - Wikipedia

    en.wikipedia.org/wiki/Network_performance

    The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
