Kuyini inkumbulo?

Abantu abaningi kungenzeka abanesifiso sokwazi lokho imemori. Ungakwazi ukukhuluma ngakho. Memory - Imemori yesimiso lapho processor has ithuba lokusingatha in umsebenzi olulodwa. It is egxile kwisitoreji sesikhashana ticondziso idatha ezidingekayo ukuze wokugaya ukwenza imisebenzi. Abaningi bangase bazibuze, yini edingekayo RAM? Inikeza ukudluliswa ngqo idatha ku-processor. Ngamunye iseli inkumbulo linekheli lalo. amakhompyutha zanamuhla zisebenzisa kumadivayisi inkumbulo, wahlela ngokuvumelana nesimiso esisha ashukumisayo okungahleliwe ukufinyelela ubuchwepheshe. Lo mqondo kusikisela ukuthi lapho wamanje inkumbulo ukufinyelela is hhayi kunakwe oda imisebenzi odlule, kanye indawo idatha kumemori. RAM zingenziwa njengoba iyunithi ehlukile noma yingxenye computer eyodwa-chip.

Ukuhlaziya umbuzo, yini inkumbulo, kuyafaneleka ethi idatha equkethwe kuwo, zitholakala kuphela uma nginomdlandla, okungukuthi, lapho ikhompyutha ivuliwe. Ukungabikho voltage ku amamojula inkumbulo kuholela ekulahlekelweni ephelele ulwazi RAM yayo noma ukuhlanekezela. Memory - lena esitolo idatha yesistimu yokusebenza kanye nezinhlelo ezisebenza ukwenza, ngakho senani incike inani imisebenzi engenziwa ngesikhathi esisodwa. Umthamo evamile RAM kuleliphuzu kusuka 1 kuya 4 gigabytes, okungase kube khona enkundleni eyodwa noma ngaphezulu komzila. Abenzi ezithandwa kakhulu ungowesilisa, Samsung, Kingston.

Ngakho, ngizitshela ukuthi inkumbulo esinjalo, kubalulekile ukuba niyikhulume dram. Lolu hlobo isetshenziswa izinhlelo eziningi zalezi zinsuku. Inzuzo yayo eyinhloko ukuthi iseli uvalwe kakhulu igcwele, okungukuthi, ngo-chip encane ibekwe eziningi izingcezu, futhi ikuvumela ukudala wememori ezinkulu. Uma uqala i-software amafayela alayishwe ku-RAM, lapho kuba inqubo ukusebenza isicelo. imiyalo CPU abathola isahlulelo, imiphumela zazo futhi elondolozwe ku-RAM. Ngo inqubo ukusebenza sombhalo kwimemori egcinwe amakhodi okhiye sicindezelwe, futhi uma uchofoza "Londoloza" okuqukethwe RAM egcinwe disk kanzima njengoba ifayela.

Khathi amaseli imemori ngokungu capacitors chip zibambe amacala. Nalokhu hlobo inkumbulo izinkinga ezihlobene eziphathelene dynamism wayo, okungukuthi ukuvuselelwa yayo njalo, njengoba kungenzeka ngenye idatha elahlekile. I ukukhishwa CPU, ngoba umjikelezo lokhu inqubo ngamunye, kuthatha imijikelezo ambalwa. amakhompyutha Old bachithe cishe 10% CPU isikhathi ukuvuselelwa, kodwa izinhlelo yesimanje usebenzisa imali engaphansi kuka-1%. kumadivayisi inkumbulo Dynamic usebenzise Transistor olulodwa ukugcina omunye kancane, Nokho zingabantu ibe banzi kunezinye izinhlobo chips.

Manje singasho mayelana okungahleliwe ukufinyelela inkumbulo. Lokhu uhlobo inkumbulo ikuvumela ukuba abhale noma ukufunda idatha nganoma isiphi isikhathi. Kungenzeka ashukumisayo noma static. RAM Static-trigger imelelwa izakhi isitoreji, evumela ukufunda ngaphandle ukulahleka kolwazi. inkumbulo Dynamic lisetshenziswa njengedivaysi umthamo inkumbulo cell, okudinga yokutakula ngesikhatsi isitoreji kanye nokusetshenziswa okwalandela. RAM Modern ashukumisayo bephethe ukuvuselelwa kanye ukuvumelanisa izindlela, kodwa bona musa ihluke static kumasiginali zangaphandle.

Ngakho, kufanele kucace ukuthi inkumbulo enjalo.
