Random nkag tau nco yog ib qho ntawm lub cim xeeb hauv computer uas yog lub luag haujlwm khaws cia ib ntus ntawm cov ntaub ntawv thiab cov lus qhia tsim nyog rau kev ua haujlwm ntawm lub hauv paus thiab rau kev ua qee yam haujlwm. Nov yog ib qho ntawm cov hauv ntawv uas cuam tshuam rau kev ua tiav ntawm koj lub khoos phis tawm ntawm koj lub computer.
Cov Lus Qhia
Kauj ruam 1
RAM yog ib los yog ntau daim npav ntsia ntawm qhov system board ntawm lub khoos phis tawm. Cov ntaub ntawv muaj nyob rau hauv RAM siv tau yog tias lub computer muab qhib. Tus nqi ntawm RAM cuam tshuam cov haujlwm uas lub computer tuaj yeem ua tau tib lub sijhawm. Cov microcontrollers feem ntau muaj lawv tus kheej nkag mus siv lub cim xeeb, cov nplov uas yog ib feem ntawm lawv cov qauv.
Kauj ruam 2
Feem ntau cov khoos phis tawj siv cov heap nco modules. Hom RAM no yog tus pheej yig, tab sis muaj kev ua qis dua. Qhov zoo dua ntawm cov laug cam yog tias lawv tuaj yeem khaws cov ntaub ntawv ntau dua rau ib cheeb tsam hauv qhov sib piv nrog cov ntsuas cim zoo li qub. Feem ntau, hom tom kawg ntawm lub cim xeeb yog siv thaum tsim lub cim xeeb lub cim xeeb, uas yog lub hauv paus ntawm lub hauv paus nqa. Qhov no vim yog qhov tseeb tias hom kev nco no kim dua, tab sis muaj kev ua haujlwm siab ceev.
Kauj ruam 3
Dynamic nco yog ib qho kev lag kev luam ntawm RAM. Vim tias qee qhov kev tsim qauv rau kev tsim lub cim xeeb dynamic teeb meem, ob peb cov teeb meem tau daws tam sim. Cov ntsiab lus no tsis yog ntau heev, thiab lawv cov khoom lag luam tsis tas yuav them nuj nqis loj. Qhov tsis zoo ntawm cov qauv no suav nrog qeeb qeeb ntawm lawv txoj haujlwm, vim muaj ntau yam nyob rau hauv ib zaug.
Kauj ruam 4
Static nco muaj qhov ntau dua ua kom nrawm dua. Nws yog feem ntau siv hauv kev lag luam hauv nruab nrab. Nws lub ntim, raws li txoj cai, yog tus me, tab sis nws yog qhov tsim nyog los ua cov txheej txheem cov ntaub ntawv yuav tsum tau ntws.
Kauj ruam 5
Daim npav nco ua ke tau muab faib ua ntau hom: DIMM, DDR1, 2 thiab 3. Lawv txhua tus muaj cov channel tshwj xeeb rau kev sib txuas nrog cov motherboard, uas txwv tsis pub muaj qhov txhim kho ntawm cov tsis raug.
