  7. Vector clock - Wikipedia

    en.wikipedia.org/wiki/Vector_clock

    A vector clock is a data structure used for determining the partial ordering of events in a distributed system and detecting causality violations. Just as in Lamport timestamps, inter-process messages contain the state of the sending process's logical clock. A vector clock of a system of N processes is an array /vector of N logical clocks, one ...

  8. Time-invariant system - Wikipedia

    en.wikipedia.org/wiki/Time-invariant_system

    The time-dependent system function is a function of the time-dependent input function. If this function depends only indirectly on the time-domain (via the input function, for example), then that is a system that would be considered time-invariant. Conversely, any direct dependence on the time-domain of the system function could be considered ...

  9. Folksonomy - Wikipedia

    en.wikipedia.org/wiki/Folksonomy

    Folksonomy is a classification system in which end users apply public tags to online items, typically to make those items easier for themselves or others to find later. Over time, this can give rise to a classification system based on those tags and how often they are applied or searched for, in contrast to a taxonomic classification designed by the owners of the content and specified when it ...
