RAM ndi chiyani? | Tanthauzo la Chikumbutso Chofikira

RAM imayimira Kukumbukira Kwachisawawa , ndichofunikira kwambiri pakompyuta chomwe chimafunikira kuti kompyuta iziyendetsa, RAM ndi njira yosungira CPU imagwiritsa ntchito kusungira zomwe zikugwira ntchito kwakanthawi. Ikhoza kupezeka pamitundu yonse yamagetsi monga ma Smartphones, ma PC, mapiritsi, maseva, ndi zina zambiri.

RAM ndi chiyani? | Tanthauzo la Chikumbutso Chofikira



Popeza kuti chidziwitso kapena chidziwitsochi chimapezeka mwachisawawa, nthawi yowerengera ndi kulemba imathamanga kwambiri poyerekeza ndi njira zina zosungira monga CD-ROM kapena ma Hard Hard Disk pomwe ma data amasungidwa kapena kupezedwa motsatana motsatizana zomwe zimachedwa pang'onopang'ono chifukwa chotsatira ngakhale zochepa zazosungidwa pakati pazotsatira zomwe tidzayenera kutsata mwatsatanetsatane.



momwe mungasinthire msakatuli wam'mbali kuti musasinthe

RAM imafuna mphamvu kuti igwire ntchito, chifukwa chake zomwe zimasungidwa mu RAM zimafufutidwa mukangotseka kompyuta. Chifukwa chake, imadziwikanso kuti Wosakhazikika Memory kapena yosakhalitsa yosungirako.

Bokosi la amayi limatha kukhala ndi malo osiyanasiyana okumbukira, owerenga mavabodi ambiri amakhala pakati pa 2 ndi 4 a iwo.



Kuti Data kapena mapulogalamu azigwiritsidwa ntchito pamakompyuta, amafunika kuti ayambe kulowetsedwa mu ram.

Chifukwa chake dongosololi kapena pulogalamuyo imasungidwa koyamba pa hard drive kenako kuchokera pa hard drive, imayendetsedwa ndikuyika RAM. Ikangodzaza, CPU imatha kulumikizana ndi pulogalamuyo kapena kuyendetsa pulogalamuyo tsopano.

Pali zambiri kapena zambiri zomwe zimafikiridwa pafupipafupi kuposa ena, ngati kukumbukira ndikotsika kwambiri sikungathe kusunga zonse zomwe CPU imafunikira. Izi zikachitika ndiye kuti zina mwazomwe zimasungidwa zimasungidwa pa hard drive kuti zibwezere kukumbukira pang'ono.



Komanso Werengani: Kodi Windows Registry & Momwe imagwirira ntchito ndi chiyani?

Chifukwa chake m'malo mwazidziwitso zomwe zimachokera ku RAM kupita ku CPU, ziyenera kuzitenga kuchokera pa hard drive zomwe zimachedwetsa kufikira, izi zimachedwetsa kompyuta. Izi zitha kuthetsedwa mosavuta powonjezera kuchuluka kwa RAM yomwe kompyuta ingagwiritse ntchito.

Mitundu iwiri ya RAM

i) DRAM kapena RAM Yamphamvu

Dram ndikukumbukira komwe kumakhala ndi ma capacitors, omwe ali ngati ndowa yaying'ono yomwe imasungira magetsi, ndipo ili m'ma capacitors amenewa imakhala ndi chidziwitso. Chifukwa dram ali ndi ma capacitors omwe amafunika kutsitsimutsidwa ndi magetsi nthawi zonse, samatha kubweza nthawi yayitali. Chifukwa ma capacitors amayenera kutsitsimutsidwa mwamphamvu, ndipomwe amapeza dzina. Mtundu wa ukadaulo wa RAM sukugwiritsidwanso ntchito chifukwa chakukula kwa ukadaulo wa RAM wogwira mtima kwambiri womwe tikambirana mtsogolo.

ii) SDRAM kapena Synchronous DRAM

Iyi ndi ukadaulo wa RAM womwe umagwiritsidwa ntchito kwambiri pamagetsi athu tsopano. SDRAM imakhalanso ndi ma capacitors ofanana ndi DRAM, komabe, kusiyana pakati pa SDRAM ndi DRAM ndilo liwiro, ukadaulo wakale wa DRAM umayenda pang'onopang'ono kapena ukugwira ntchito mosavomerezeka kuposa CPU, izi zimapangitsa kuti liwiro likusunthike chifukwa ma siginolo sanagwirizane.

SDRAM ikuyenda molumikizana ndi koloko ya nthawi, ndichifukwa chake imathamanga kuposa DRAM. Zizindikiro zonse zimalumikizidwa ndi koloko yamachitidwe kuti ziziyendetsedwa bwino.

RAM imalowetsedwa mu bolodi la amayi ngati ma module ogwiritsa ntchito omwe amatchedwa SIMMs (Ma module a mu mzere umodzi) ndi ma DIMM (ma module awiri okumbukira mu-line) . Amatchedwa DIMM chifukwa ali ndi mizere iwiri yoyimirira ya zikhomozi mbali imodzi mbali imodzi pomwe ma SIMM ali ndi mzere umodzi wa zikhomo mbali imodzi. Mbali iliyonse ya gawoli ili ndi zikhomo 168, 184, 240 kapena 288.

Kugwiritsa ntchito ma SIMM tsopano kulibenso chifukwa kukumbukira kwa RAM kudawirikiza Ma DIMM .

Ma DIMM awa amabwera mosiyanasiyana, omwe amakhala kulikonse pakati pa 128 MB mpaka 2 TB. Ma DIMM amatumiza ma bits 64 a data nthawi imodzi poyerekeza ndi ma SIMM omwe amasamutsa ma bits 32 a data nthawi imodzi.

SDRAM imawerengedwanso mothamanga mosiyanasiyana, koma tisanalowemo, tiyeni timvetsetse njira yanjira.

Kuthamanga kwa CPU kumayesedwa munthawi yamawotchi, motero munthawi imodzi, ma 32 kapena 64 ma data amasunthidwa pakati pa CPU ndi RAM, kusinthaku kumatchedwa njira ya data.

Chifukwa chake kuthamanga kwa CPU kumakhala kothamanga kwambiri pomwe kompyuta izikhala.

Momwemonso, ngakhale SDRAM ili ndi liwiro la wotchi pomwe kuwerenga ndi kulemba kumatha kuchitika. Chifukwa chake liwiro la wotchi ya RAM limathamanga mwachangu momwe ntchitoyo imathandizira kukulitsa ntchitoyo. Izi zimayeza kuchuluka kwa mayendedwe omwe amatha kuwerengera mu megahertz. Chifukwa chake, ngati RAM idavoteledwa pa 1600 MHz, imayenda maulendo mabiliyoni 1.6 pamphindikati.

Chifukwa chake, tikukhulupirira kuti izi zakuthandizani kumvetsetsa momwe RAM ndi mitundu yosiyanasiyana ya matekinoloje a RAM amagwirira ntchito.
