kungani ukushintsha umongo kukubi ekusebenzeni kwekhompyutha?
Ukushintshwa kokuqukethwe, okwenzeka lapho inqubo imiswa yi-CPU futhi enye inqubo iqala ukusebenza kungathinta ukusebenza kwezinhlelo zekhompyutha ngezizathu ezimbalwa. Isenzo sokushintsha umongo ngokwaso asidli isikhathi esiningi. Ukusebenza kwangempela kwe-hit kuvela eqinisweni lokuthi izinqubo ezahlukahlukene zinezikhala ezahlukahlukene zamakheli enkumbulo ebonakalayo ngakho-ke zonke izilondolozi kusistimu zidinga ukwenziwa zingasebenzi futhi zikhishwe. Njengoba kunomehluko omkhulu kangaka ekutheni i-cpu ingasebenza ngokushesha kangakanani uma kuqhathaniswa nokuthi imiyalo nemininingwane ingalandwa ngokushesha kangakanani kwimemori eyinhloko, lezi zinto zigcinwa eduze kwe-cpu ezindaweni zokulondoloza isikhashana. Ngisho nesikhombisi esiqondisa amakheli angokoqobo kumakheli angokoqobo sibekwe ngekheshi ukuze ukufinyelela enkumbulweni kusheshe. Lapho inqubo entsha ifakwa yi-CPU enendawo yamakheli ehlukile nokufaniswa kwamakheli abonakalayo kuya kokungokoqobo, yonke idatha esesitsheni ayivumelekile futhi idinga ukuhlanzwa. Lokhu kushiya i-cpu inezinqolobane ezingenalutho okumele zakhiwe kabusha kusuka ekuqaleni kwenqubo entsha, okusho ukuthi kuzoba nokwehla okukhulu ekutholeni imiyalo nedatha ngoba manje lezi zizovela kwimemori eyinhloko, ehamba kancane kakhulu kune-cpu's cache.
