Random Access Memory, lossis RAM (hais ua ramm), yog lub cev kho vajtse hauv lub computer uas khaws cov ntaub ntawv ib ntus, ua haujlwm ua lub computer "ua haujlwm" nco.
Ntxiv RAM tso cai rau lub khoos phis tawj ua haujlwm nrog cov ntaub ntawv ntau ntxiv nyob rau tib lub sijhawm, uas feem ntau cuam tshuam rau tag nrho cov haujlwm ua haujlwm.
Qee lub tuam txhab nrov ntawm RAM suav nrog Kingston, PNY, Crucial, thiab CORSAIR.
Muaj ntau hom RAM, yog li koj tuaj yeem hnov nws hu los ntawm lwm lub npe. Nws tseem hu ua lub cim xeeb tseem ceeb, lub cim xeeb sab hauv, thawj qhov chaw cia, thawj lub cim xeeb, nco "stick", thiab RAM "stick".
RAM yog dab tsi?
Muab qhov yooj yim, lub hom phiaj ntawm RAM yog muab kev nyeem nrawm thiab sau ntawv nkag mus rau lub cuab yeej cia. Koj lub khoos phis tawj siv RAM los thauj cov ntaub ntawv vim tias nws nrawm dua li khiav tib cov ntaub ntawv ncaj qha tawm ntawm lub hard drive.
Xav txog RAM zoo li lub rooj ua haujlwm. Lub rooj yog siv rau kev nkag mus ceev rau cov ntaub ntawv tseem ceeb, cov cuab yeej sau ntawv, thiab lwm yam khoom uas koj xav tau tam sim no. Yog tsis muaj lub rooj, koj yuav khaws txhua yam khaws cia hauv cov tub rau khoom thiab cov ntaub ntawv txee, txhais tau tias nws yuav siv sijhawm ntev dua los ua koj cov dej num txhua hnub txij li koj yuav tsum tau mus tas li mus rau hauv cov thawv ntim khoom kom tau txais yam koj xav tau, thiab tom qab ntawd siv sijhawm ntxiv. lawv ncaim mus.
Ib yam li ntawd, tag nrho cov ntaub ntawv uas koj nquag siv hauv koj lub computer (lossis smartphone, ntsiav tshuaj, thiab lwm yam) tau khaws cia hauv RAM ib ntus. Hom kev nco no, zoo li lub rooj hauv qhov piv txwv, muab sijhawm nyeem / sau nrawm dua li siv lub hard drive. Feem ntau cov hard drives qeeb dua li RAM vim muaj kev txwv lub cev xws li kev sib hloov ceev.
RAM Ua haujlwm nrog koj lub hard drive (Tab sis lawv txawv yam)
RAM feem ntau yog hu ua "nco" txawm tias lwm hom kev nco yuav muaj nyob hauv lub computer. RAM, uas yog qhov tseem ceeb ntawm tsab xov xwm no, tsis muaj dab tsi ua nrog rau cov ntaub ntawv khaws cia ntawm lub hard drive, txawm hais tias ob qho tib si feem ntau tsis raug cuam tshuam nrog ib leeg hauv kev sib tham. Piv txwv li, 1 GB ntawm lub cim xeeb (RAM) tsis zoo ib yam li 1 GB ntawm qhov chaw hard drive.
Tsis zoo li lub hard drive, uas tuaj yeem siv tau thiab rov qab los yam tsis tau poob nws cov ntaub ntawv, cov ntsiab lus ntawm RAM yeej ib txwm tshem tawm thaum lub khoos phis tawj kaw. Qhov no yog vim li cas tsis muaj koj cov kev pab cuam lossis cov ntaub ntawv tseem qhib thaum koj tig koj lub computer rov qab.
Ib txoj hauv kev uas cov khoos phis tawj tau nyob ib puag ncig qhov kev txwv no yog muab koj lub computer rau hauv hom hibernation. Hibernating lub khoos phis tawj tsuas yog luam cov ntsiab lus ntawm RAM mus rau lub hard drive thaum lub khoos phis tawj kaw thiab tom qab ntawd luam tag nrho nws rov qab rau RAM thaum lub zog rov qab.
Txhua lub motherboard tsuas yog txhawb nqa qee yam ntawm cov cim xeeb hauv qee qhov kev sib txuas, yog li nco ntsoov xyuas nrog koj lub chaw tsim khoom motherboard ua ntej yuav khoom.
Lub RAM hauv koj lub computer zoo li tus kav lossis 'Los'
Ib tus qauv qauv lossis lo ntawm lub cim xeeb ntawm lub desktop yog qhov ntev, nyias nyias ntawm cov khoom siv uas zoo li tus kav luv. Hauv qab ntawm lub cim xeeb module muaj ib lossis ntau qhov kev taw qhia rau kev teeb tsa kom raug thiab yog kab nrog ntau, feem ntau yog kub-plated, connectors.
Nco yog nruab rau hauv lub cim xeeb modules nyob rau ntawm lub motherboard. Cov slots no yooj yim los nrhiav- tsuas yog nrhiav cov pob khawm me me uas kaw lub RAM nyob rau hauv qhov chaw, nyob rau ntawm ob sab ntawm qhov zoo sib xws ntawm cov niam ntawv.
Qee qhov ntau thiab tsawg ntawm cov modules yuav tsum tau muab tso rau hauv qee qhov slots, yog li nco ntsoov xyuas nrog koj lub tuam txhab motherboard ua ntej yuav khoom lossis teeb tsa! Lwm qhov kev xaiv uas yuav pab tau yog siv cov cuab yeej cov ntaub ntawv los saib xyuas cov hom tshwj xeeb ntawm cov niam ntawv siv.
Memory modules tuaj hauv ntau lub peev xwm thiab kev hloov pauv. Cov niaj hnub nco modules tuaj yeem yuav hauv 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, 8 GB, thiab 16 + GB ntau thiab tsawg. Qee qhov piv txwv ntawm ntau hom kev nco modules suav nrog DIMM, RIMM, SIMM, SO-DIMM, thiab SO-RIMM.
MB thiab GB yog cov ntsuas ntsuas rau cov ntaub ntawv. Paub qhov txawv yog qhov tseem ceeb thaum yuav RAM thiab lwm yam "Duab ntawm pawg RAM sticks" id=mntl-sc-block-image_1-0-2 /> alt="
Ib yam li nrog CPU thiab hard drive, qhov nco koj xav tau rau koj lub khoos phis tawj yog nyob ntawm qhov koj siv, lossis npaj siv, koj lub computer rau.
Piv txwv li, yog tias koj tab tom yuav lub khoos phis tawj rau kev ua si hnyav, ces koj yuav xav tau RAM txaus los txhawb kev ua si zoo. Muaj tsuas yog 2 GB ntawm RAM muaj rau kev ua si uas pom zoo tsawg kawg 4 GB yuav ua rau kev ua haujlwm qeeb heev yog tias tsis muaj peev xwm ua si tag nrho (tshwj xeeb yog tias qhov kev pom zoo yog 8 GB lossis ntau dua).
Ntawm qhov kawg ntawm lub spectrum, yog tias koj siv koj lub computer rau lub teeb pom kev hauv internet thiab tsis muaj video streaming, games, nco-intensive daim ntawv thov, thiab lwm yam, koj tuaj yeem yooj yim khiav nrog lub cim xeeb tsawg.
Ib yam mus rau daim ntawv thov kev kho video, cov kev pab cuam uas hnyav ntawm 3D cov duab, thiab lwm yam. Koj tuaj yeem tshawb pom ua ntej koj yuav lub computer tsuas yog RAM ntau npaum li cas ib qho kev pab cuam lossis kev ua si xav tau, feem ntau teev nyob rau hauv "system. xav tau" cheeb tsam ntawm lub vev xaib lossis lub thawv khoom.
Nws yuav nyuaj rau nrhiav lub desktop tshiab, laptop, lossis txawm tias ntsiav tshuaj uas tuaj nrog tsawg dua 2 txog 4 GB ntawm RAM ua ntej. Tshwj tsis yog tias koj muaj lub hom phiaj tshwj xeeb rau koj lub khoos phis tawj sib nrug los ntawm kev ua yeeb yaj kiab tsis tu ncua, kev saib hauv internet, thiab kev siv ib txwm siv, tej zaum koj tsis tas yuav yuav lub khoos phis tawj uas muaj RAM ntau dua li qhov ntawd.
Kev nrawm ntawm lub cuab yeej txwv tsis yog los ntawm RAM nkaus xwb tab sis lwm cov khoom xws li processor thiab hard drive, txhais tau tias koj lub khoos phis tawj tuaj yeem muaj cov khoom siv siab kawg tab sis RAM me me, uas yuav cuam tshuam rau kev ua haujlwm tag nrho. Tib yam muaj tseeb hauv kev thim rov qab: ntau RAM yog qhov zoo tab sis yuav tsis ua rau muaj kev cuam tshuam loj heev yog tias CPU qeeb.
daws teeb meem RAM
Thawj qhov koj yuav tsum ua yog tias koj xav tias muaj teeb meem nrog ib lossis ntau dua RAM sticks yog rov ua dua lub cim xeeb modules. Yog tias ib qho ntawm RAM sticks tsis tau muab tso rau hauv nws qhov chaw ntawm lub motherboard, nws muaj peev xwm txawm tias ib lub pob me me tuaj yeem tsoo nws tawm ntawm qhov chaw thiab ua rau muaj teeb meem nco uas koj tsis muaj ua ntej.
Yog tias rov kho lub cim xeeb tsis ua kom cov tsos mob zoo dua, peb pom zoo kom siv ib qho ntawm cov kev sim ntsuas kev nco dawb no. Txij li thaum lawv ua haujlwm sab nraud, lawv ua haujlwm nrog txhua yam ntawm PC-Windows, Mac, Linux, thiab lwm yam.
Koj qhov kev xaiv zoo tshaj plaws yog los hloov lub cim xeeb hauv koj lub computer yog tias ib qho ntawm cov cuab yeej txheeb xyuas qhov teeb meem, txawm tias me npaum li cas.
Cov ntaub ntawv tshaj tawm ntawm RAM
Txawm hais tias RAM tau piav qhia raws li qhov tsis txaus ntseeg hauv lub ntsiab lus ntawm lub vev xaib no (nrog rau lub cim xeeb hauv computer), nws kuj muaj nyob rau hauv daim ntawv tsis hloov pauv, tsis hloov pauv hu ua nyeem nkaus xwb (ROM). Flash drives thiab cov khoom siv hauv xeev, piv txwv li, yog cov hloov pauv ntawm ROM uas khaws lawv cov ntaub ntawv txawm tias tsis muaj zog, tab sis tuaj yeem hloov kho.
Muaj ntau hom RAM, tab sis ob lub ntsiab yog static RAM (SRAM) thiab dynamic RAM (DRAM). Ob leeg yog volatile. SRAM sai dua tab sis kim dua los tsim dua DRAM, uas yog vim li cas tom kawg yog ntau dua hauv cov khoom siv niaj hnub no. Txawm li cas los xij, SRAM qee zaum pom hauv cov koob me me hauv ntau qhov chaw hauv lub computer, xws li nrog CPU thiab ua lub cim xeeb hard drive.
Qee software, zoo li SoftPerfect RAM Disk, tuaj yeem tsim qhov hu ua RAM disk, uas yog qhov tseem ceeb ntawm lub hard drive uas muaj nyob hauv RAM. Cov ntaub ntawv tuaj yeem khaws cia rau, thiab qhib los ntawm, lub disk tshiab no zoo li nws yog lwm yam, tab sis lub sijhawm nyeem / sau tau nrawm dua li siv lub hard disk li niaj zaus vim RAM nrawm dua.
Qee qhov kev khiav haujlwm tuaj yeem siv qhov hu ua lub cim xeeb virtual, uas yog qhov txawv ntawm RAM disk. Qhov no yog qhov tshwj xeeb uas tso tseg qhov chaw hard disk rau siv raws li RAM. Thaum ua li ntawd tuaj yeem ua kom tag nrho cov cim xeeb muaj rau cov ntawv thov thiab lwm yam kev siv, nws yuav cuam tshuam tsis zoo rau kev ua haujlwm vim qhov tseeb tias hard drives qeeb dua li RAM sticks.
