RAM - lokho kusho ukuthini futhi kusebenza kanjani?

Ngokuthenga ikhompyutha entsha, njalo unake izici zayo, kwaba ubuso bakhe futhi izinzuzo main. Phakathi nemingcele abaningi kudingeka ukuhlangabezana nokwehla izincwadi ezintathu - RAM. Kuyini futhi kungani udinga ukuba? Kuyini lemali elilungile kwadingeka kwezinhlelo operation evamile PC? Mayelana zonke lokhu kamuva.

Incazelo nemisebenzi

RAM - Finyelela okungahleliwe Memory ukugcina idatha lapho ikhompyutha. Okungukuthi, zonke izinqubo egijima kanye nemisebenzi ku-PC yakho kule ndawo lilondolozwe sangempela, lapho kamuva kusetshenzwe yi-processor. Ungase futhi uthole ukuthi igama lesibili zale divayisi - RAM, ukuthi English imele okungahleliwe ukufinyelela inkumbulo, noma "ngohlelo kwetheminali ezingafanele." RAM enezinto eziningi imisebenzi ebalulekile, ngaphandle lapho sonke isimiso akunakwenzeka:

1. Isitoreji aggregate izibalo okwenziwa yi-processor.
2. imiyalo Isitoreji nezenzo kamuva ithunyelwa CPU ukuze kusebenziswe futhi ukudlala. Idatha angadluliselwa hhayi kuphela ngqo processor, kodwa futhi inkumbulo isilondolozi salo, esiwulwazi ngokushesha okuningi kunalokho inkumbulo RAM.
3. Ukubhala futhi ukufunda okuqukethwe kweseli

Izici ukusebenza

RAM uyakwazi ukugcina ulwazi kuphela lapho i-PC. Ngenxa yale njongo kubalulekile ukugcina yonke idatha, ngawo ukusebenza kwi-hard drive yakho. RAM - Kuyini? Ngamanye amazwi, lokhu yesitoreji, lapho imisebenzi zonke izinqubo kanye nezinhlelo. It sidlula RAM ukuhlela ulwazi ashukumisayo ukusakaza. Okungahleliwe-ukufinyelela inkumbulo (RAM) - kuyini futhi ukuthi kushiwoni lokhu? Lobu buchwepheshe likuvumela ukufunda nokubhala kunoma iyiphi indawo inkumbulo nganoma isiphi isikhathi.

Indlela okusebenza?

RAM kanjani? Kuyini, uyazi. Futhi asebenze kanjani? Kasibili iyiphi inkumbulo inamaseli, ngamunye wabo linekheli lalo. Naphezu kwakho konke lokho, ziqukethe nenani elilinganako ibhithi zilingane ngenani 8 (8 izingcezu = 1 ibhayithi). Lona iyunithi ubuncane yiluphi ulwazi. Zonke amakheli kukhona efomini izinombolo kanambambili (0 no-1) uqobo kanye idatha. Amaseli komakhelwane, ifa amakheli elandelanayo. Abaningi imiyalo abazenzi usebenzisa "izwi", ezindaweni inkumbulo, ehlanganisa 4 noma 8 amabhayithi.

zinhlobo ukwehluka

ngezigaba Jikelele uhlukanisa divayisi ezimbili izinhlobo inkumbulo: SRAM (static) kanye dram (okuguqukayo). Eyokuqala isetshenziswa njengophawu inkumbulo enqolobaneni CPU udlala indima imemori computer yesibili. Noma yimuphi yakhiwa SRAM trigger ukuthi kungaba ezimbili uthi: "ku" futhi "off". Bahlanganisa inqubo eyinkimbinkimbi yokwakha neketanga zobuchwepheshe, ngenxa okuyinto isikhala kakhulu. Intengo zedivayisi kuyoba siphezulu kunamanye dram, lapho azikho trigger, ngenxa lapho RAM etholwe compact kodwa has eyodwa Transistor nokukodwa capacitor (isb - RAM DDR2). Inani elikhulu ngaleso sikhathi asebenzayo komyalelo wokungabi 4 GB, uma endaweni yesikhulumi kwikhompyutha senzelwe imidlalo ke Kunconywa ukwandisa le nombolo by izikhathi 2. Namuhla saqonda RAM - lokho kusho ukuthini futhi kusebenza kanjani. Manje umfundi isimiso esiyisisekelo okusebenzela kule divayisi.
