I-RAM imele inkumbulo yokufinyelela okungahleliwe , iyingxenye ye-elekthronikhi ebaluleke kakhulu edingekayo ukuze ikhompuyutha isebenze, i-RAM iwuhlobo lokugcina CPU isebenzisa ukugcina idatha esebenzayo yamanje okwesikhashana. Ingatholakala kuzo zonke izinhlobo zamadivayisi ekhompyutha afana nama-Smartphones, ama-PC, amaphilisi, amaseva, njll.
Njengoba ulwazi noma idatha ifinyelelwa ngokungahleliwe, izikhathi zokufunda nokubhala zishesha kakhulu uma ziqhathaniswa nezinye izindlela zokugcina ezifana I-CD-ROM noma Ama-Hard Disk Drives lapho idatha igcinwa khona noma ibuyiswe ngokulandelana okuyinqubo ehamba kancane njengomphumela wokubuyisa ngisho nenani elincane ledatha egcinwe phakathi nokulandelana kuzodingeka sidlule kukho konke ukulandelana.
I-RAM idinga amandla ukuze isebenze, ngakho-ke ulwazi olugcinwe ku-RAM luyasulwa ngokushesha nje lapho ikhompuyutha icishiwe. Ngakho-ke, yaziwa nangokuthi Inkumbulo Eguquguqukayo noma Isitoreji Sesikhashana.
I-Motherboard ingaba nenani elihlukahlukene lezikhala zememori, i-Motherboard yomthengi emaphakathi izoba phakathi kwezi-2 nezi-4 zazo.
Ukuze Idatha noma izinhlelo zisetshenziswe kukhompyutha, idinga ukulayishwa enqameni kuqala.
Ngakho-ke idatha noma uhlelo lugcinwa kuqala ku-hard drive bese lusuka ku-hard drive, lubuyiswe futhi lulayishwe ku-RAM. Uma isilayishiwe, i-CPU manje isingakwazi ukufinyelela idatha noma iqalise uhlelo manje.
Kunolwazi oluningi noma idatha efinyelelwa kaningi kunezinye, uma inkumbulo iphansi kakhulu ingase ingakwazi ukubamba yonke idatha edingwa yi-CPU. Uma lokhu kwenzeka bese enye idatha eyeqile igcinwa ku-hard drive ukuze kunxeshezelwe inkumbulo ephansi.

Ngakho esikhundleni sokuthi idatha isuka ngqo ku-RAM iye ku-CPU, kufanele iyibuyisele ku-hard drive enesivinini sokufinyelela esihamba kancane, le nqubo inciphisa kakhulu ikhompyutha. Lokhu kungasingathwa kalula ngokwandisa inani le-RAM etholakalayo ukuze isetshenziswe ikhompuyutha.

Izinhlobo ezimbili ezahlukene ze-RAM
i) I-DRAM noma i-Dynamic RAM
I-Dram iyinkumbulo equkethe ama-capacitor, efana nebhakede elincane eligcina ugesi, futhi ikula ma-capacitor egcina ulwazi. Ngenxa yokuthi i-dram inama-capacitor adinga ukuvuselelwa ngogesi njalo, awabambi imali isikhathi eside. Ngoba ama-capacitor kufanele avuselelwe ngamandla, yilapho athola khona igama. Lolu hlobo lobuchwepheshe be-RAM alusasetshenziswa ngenxa yokuthuthukiswa kobuchwepheshe be-RAM obusebenza kahle kakhulu nobusheshayo esizoxoxa ngaso ngaphambili.
ii) I-SDRAM noma i-Synchronous DRAM
Lobu ubuchwepheshe be-RAM obusetshenziswa kakhulu kuma-electronics wethu manje. I-SDRAM futhi inama-capacitor afana ne-DRAM, noma kunjalo, i umehluko phakathi kwe-SDRAM ne-DRAM ijubane, ubuchwepheshe obudala be-DRAM buhamba kancane noma busebenza ngokulingana kune-CPU, lokhu kwenza isivinini sokudlulisa sibambezeleke ngoba amasiginali awahlangani.
I-SDRAM isebenza ngokuvumelanisa newashi lesistimu, yingakho ishesha kune-DRAM. Wonke amasignali aboshelwe ewashini lesistimu ukuze kube nesikhathi esilawulwa kangcono.
I-RAM ixhunywe ebhodini lomama ngendlela yamamojula akhishwa umsebenzisi abizwa Ama-SIMM (amamojula enkumbulo esemgqeni owodwa) kanye nama-DIMM (amamojula wenkumbulo yomugqa okabili) . Ibizwa ngokuthi ama-DIMM ngoba inemigqa emibili ezimele yala maphini eyodwa ohlangothini ngalunye kuyilapho ama-SIMM enomugqa owodwa kuphela wamaphini ohlangothini olulodwa. Uhlangothi ngalunye lwemojula lunamaphini angu-168, 184, 240 noma angu-288.
Ukusetshenziswa kwama-SIMM manje akusasebenzi njengoba umthamo wenkumbulo we-RAM uphindwe kabili ngawo Ama-DIMM .
Lawa ma-DIMM eza ngamakhono enkumbulo ahlukene, aqala noma yikuphi phakathi kuka-128 MB kuya ku-2 TB. Ama-DIMM adlulisa amabhithi edatha angu-64 ngesikhathi uma kuqhathaniswa nama-SIMM adlulisa amabhithi angu-32 edatha ngesikhathi.
I-SDRAM iphinda ikalwe ngesivinini esihlukile, kodwa ngaphambi kokuthi sijule kulokho, masiqonde ukuthi iyiphi indlela yedatha.
Isivinini se-CPU silinganiswa ngemijikelezo yewashi, ngakho emjikelezweni wewashi owodwa, amabhithi angu-32 noma angu-64 edatha adluliselwa phakathi kwe-CPU ne-RAM, lokhu kudluliselwa kwaziwa ngokuthi umzila wedatha.
Ngakho-ke lapho isivinini sewashi siphezulu se-CPU ikhompyutha izoshesha kakhulu.

Ngokufanayo, ngisho ne-SDRAM inejubane lewashi lapho ukufunda nokubhala kungenzeka khona. Ngakho-ke lapho iwashi le-RAM lishesha ngesivinini lapho imisebenzi yenzeka ngokushesha ithuthukisa ukusebenza kwephrosesa. Lokhu kukalwa ngenani lemijikelezo engayenza ibalwe nge-megahertz. Ngakho-ke, uma i-RAM ilinganiselwe ku-1600 MHz, yenza imijikelezo eyizigidi eziyizinkulungwane ezingu-1.6 ngomzuzwana.
Ngakho-ke, sithemba ukuthi lokhu kukusize uqonde ukuthi i-RAM nezinhlobo ezahlukene zobuchwepheshe be-RAM zisebenza kanjani.
