Yintoni memory (RAM)?

Baleka iinkqubo kwi computer siqu ngoku yonke schoolchild. Kodwa yintoni na ayimangalisi: ukuba ubuncinane nolwazi olusisiseko iinkqubo wenzeka ngaphakathi iiyunithi ze-elektroniki, abaninzi nje musani ingqalelo kuyimfuneko. Kodwa ke mfundi, njengoko indoda zizifundiswa, ngokuqinisekileyo ufuna ukujongana umbuzo wokuba yintoni RAM. Olu lwazi luya kuphela banzi imimango zam, kodwa ukuvumela ukuba ukhethe ukugcinwa isebenzayo ye ezizezayo computer babo.

Ngoko ke, yintoni na memory? Nasiphi na isixhobo computing, nokuba wokubala esilula, leyo ibala undoqo ngaphandle ngokuyimfuneko uthwele eziliqela iindidi kwinkumbulo. Uhlobo lokuqala - ROM (Funda kuphela Inkumbulo), kunye, ngokulandelelana, a RAM (imemori yofikelelo oluzenzekelayo) yesibini. Umsebenzisi unomdla koko RAM, kuya kubakho iingxaki eninzi xa ukhumbula basisishunqulelo IsiNgesi: ROM kunye RAM. Rom - Lo imemori yokufunda-kuphela (Funda kuphela), kunye RAM - kananjalo emazishicilelwe (Random Access). Maxa wambi ungeno kwi ROM nangoku kunokwenzeka, kodwa iindlela ezizodwa (senkqubo njl). Ukuba achaze oko RAM, ukunika umzekelo ikhaltyhuleyitha.

Emva ngokucinezela ngamandla iqhosha ukusuka ROM kufundwa kwaye luvuleke izibalo firmware, kwenziwe uphando ngobume lamaqhosha. Apha umsebenzisi ecofa iqhosha kunye nenombolo. Nokuba ukuba ubalo elula kuyimfuneko ukwenza 4: amanani amabini, iimpawu amanyathelo kunye nokulingana. Njani calculator "uyakhumbula" odlulileyo ukuya ngokucofa "lilingana" ngena? amaxabiso azo agcinwe kwinkumbulo. Computer, naliphi na, nkqu software ofisi izibalo CPU, amaxabiso iindlela zam RAM.

Le peculiarity ye RAM kukuba esebenza ngokukhawuleza (xa kuthelekiswa ne-ROM), kudla isixa esikhulu noko wamandla, kwaye idata egcinwe kuyo lugciniwe njenge gama ombane isicelo.

Xa computer RAM engineering ngokwasemzimbeni endaba samaxande textolite (ngezithandelo, iimodyuli) kunye nabo pin ikama-uhambisa, kweentambo iitreki conductive kunye iseti memory neetshiphusi. Iminqongo kufakwa kwiindawo zokubeka kwi motherboard.

RAM zavela kunye ngeekhompyutha. iintlobo zalo ayizange isetyenziswe kuphela! It Kutshanje ababhekisi phambili zange azame "uzakhe i ivili", ngokuba intliziyo uphuhliso kukho RAM DDR. Phambi ngokundwendwela Intel chipsets 845 kunye VIA KT266 inkxaso ezintsha standard DDR, esisetyenziswa ngokubanzi SDRAM memory. Yaba 'run "kunye nethekhinoloji elithembekileyo, kodwa isekelwe iminqongo baya ukuswela amandla ukuze kuyikhulula amandla iziqhubekisi ezintsha. Kungoko ke yaphakanyiswa oluphuculweyo izigqibo - DDR (Double Data Rate). Umahluko omkhulu ukusuka SDRAM ophelileyo ukuya kabini isantya theoretical component. Oku kuphunyezwe lombutho idata wafunda evela iiseli kwimemori, ngaphambili, kunye nokubola yomqondiso clock generator. Le Ukuxhaphaka akatshintshi. Enyanisweni, oko kuthwalelwa phandle ukwandisa ukusetyenziswa iimodyuli iimpawu.

Ngaphezu koko, kuye kwenziwa olunye utshintsho kangako. Omnye wabo - ixesha benkumbulo yaqala ukuxhasa uqwalaselo oluzenzekelayo. olu khetho alondolozwe kuzo zonke iintlobo yanamhlanje kwinkumbulo. Iluphawu ikloko delay imodyuli supply uphawu. Okuya kusiba phantsi kwexabiso, kokukhona kungcono ukwenziwa komsebenzi, kodwa ngaphantsi uxhathiso kwi msebenzi. Xa ngokugqithiseleyo chips ixabiso elincinane bamane nje ixesha lokulungiselela zokufunda, kunye impazamo kwenzeka.

Kwakhona, ukuba ngaphambili kwi BIOS efunekayo ngqo ukuze ukhethe cacileyo umsebenzi iimodyuli, ke ngoku kuyimfuneko iparameters echazwe SPD block (sinochuku kwimodyuli), kwaye BIOS efunda nabo ngokuzenzekelayo.
