clock rate
taktų dažnis statusas T sritis informatika apibrėžtis ↑Procesoriaus darbą sinchronizuojančio generatoriaus siunčiamų impulsų dažnis. Vienas taktas – tai laikas, per kurį procesorius atlieka vieną elementarią operaciją, pavyzdžiui, loginę su bitais. Sudėtingesnė operacija (pvz., aritmetinė) atliekama per tam tikrą taktų skaičių. Matuojamas hercais (Hz). Šiuolaikinių kompiuterių taktų dažnis išreiškiamas megahercais (MHz) arba gigahercais (GHz). Taktiniu dažniu vertinama kompiuterio sparta. Tačiau tai nėra tikslus vertinimas, nes tikroji sparta priklauso ne tik nuo dažnio, bet ir nuo operacijų atlikimo algoritmų, nuo to, kiek veiksmų procesorius gali atlikti vienu metu. atitikmenys: angl. clock frequency; clock rate; clock speed; timing frequency ryšiai: dar žiūrėkprocesorius
